Prenuvo vs Ezra: what $2,499 and $999 actually buy
As of November 2026, Ezra's cheapest full-body MRI costs $999 ($899 for Function Health members) and takes about 22 minutes, and Prenuvo's Whole Body Scan costs $2,499 and takes about 50. The price gap is mostly a coverage gap: Ezra's $999 Annual MRI leaves out the chest, heart, lungs, breasts, spine, arms and legs, while Prenuvo says its Whole Body Scan runs "head to ankle", excluding only the arms and feet.

The short answer
Worth a closer look if you want the spine, chest and legs in one scan, blood tests and a results review included, and you live near one of its 24 US sites.
Prenuvo explained →Worth a closer look if price matters most, a head-to-pelvis baseline is enough, there's a partner center near you, and you have your own doctor to go through the report with.
Ezra on our compare page →Probably skip both if what you mainly want is heart-risk information or proven cancer screening. Neither MRI shows coronary plaque, and neither replaces a mammogram or colonoscopy. A calcium score CT and guideline screening cost far less and have stronger evidence.
The closer like-for-like to Prenuvo is Ezra's MRI with Spine: $1,699 ($1,499 for Function members), 47 minutes, which still leaves out the chest and legs.
How each sells it. Prenuvo sells memberships (Core, Comprehensive, Executive), each built around one scan (the shorter Focused Scan or the Whole Body Scan) plus blood tests and a results review. Ezra sells scans one at a time (Annual MRI, MRI with Spine, MRI with Skeletal and Neurological Assessment) and two CT add-ons; Function Health, which owns Ezra, sells blood tests separately.
What our own research adds. Of 11 Reddit accounts of Ezra's scan since 2025, 2 were positive, 3 mixed and 5 negative (1 awaiting results), with the negative accounts concentrated in one complaint thread about unreadable heart CTs. A writer who had both scans eight days apart in 2026 got noticeably different reports. Prenuvo's terms cap its liability at $500,000 with no arbitration opt-out; Ezra's cap is what you paid in the last six months, with a 30-day opt-out.
What this page is. A Build My Longevity research comparison, not a hands-on review. We haven't had either scan, neither company saw or approved this page, and no provider can pay to be listed or ranked here. Not medical advice: whether a scan makes sense for you is a question for your own doctor.

What each scan covers
Price per minute isn't a useful comparison. What matters is which parts of the body are in the scan you buy.
| Body area | Prenuvo Whole Body $2,499; also in Executive | Prenuvo Focused Core, $1,199 | Ezra Annual MRI $999 | Ezra with Spine $1,699 | Ezra Skeletal and Neurological $3,999 |
|---|---|---|---|---|---|
| Brain and head | Yes | Yes | Yes | Yes | Yes plus brain analysis |
| Neck and thyroid | Yes | Yes | Yes | Yes | Yes plus head and neck MR angiogram |
| Spine | Yes | No | No | Yes | Yes |
| Chest and lungs | Yes not a breast screen or plaque test | Yes | No | No | No |
| Abdomen (liver, pancreas, kidneys) | Yes | Yes | Yes | Yes | Yes |
| Pelvis | Yes | Yes | Yes | Yes | Yes |
| Hips and thighs | Yes | To mid-thigh | No | No | Yes |
| Knees and lower legs | Yes to the ankles; not diagnostic for joints | No | No | No | Knees yes; lower legs no |
| Arms and feet | No | No | No | No | No |
| Brain aneurysm assessment | Yes | No | Not stated | Not stated | Head and neck MR angiogram |
| Abdominal aortic aneurysm | Not stated separately | Not stated | Listed | Listed | Listed |
In each company's words. Prenuvo's FAQ says the whole-body exam covers "head to ankle", can identify lung nodules, images the breasts but "does not replace dedicated breast MRI", and is "not diagnostic for evaluation of the joints"; its pricing page says arms and feet aren't included, and that the Focused Scan leaves out the arms, spine and aneurysm assessment. Ezra's pricing page lists the chest, lungs, heart, breasts, arms and legs, spine, esophagus, and small and large intestines as not covered by the Annual MRI; MRI with Spine adds the spine; Skeletal and Neurological lists only the chest, lungs, heart, breasts, arms, lower legs, esophagus and bowel as not covered.
Aneurysms. Prenuvo doesn't define its "aneurysm assessment"; its FAQ says MR angiography can find aneurysms, with high sensitivity "for larger aneurysms". We read it as the brain check because Prenuvo drops it from the Focused Scan alongside the spine. Ezra lists abdominal aortic aneurysm. The two rows are not the same test.
Neither company publishes its full list of MRI sequences. Prenuvo publishes a comparison claiming its scan collects more image data than Ezra's; it is a company-made comparison of one scan each, from early 2025 (before Ezra's 22-minute scan), and image data isn't the same thing as accuracy. No study we found compares the two scans' accuracy directly.
Top tiers and add-ons
- Prenuvo Executive ($3,999) is the Whole Body Scan plus an Advanced Brain Health Scan (brain volumes measured with NeuroQuant, FDA-cleared software), an Advanced Heart Health Scan (heart-muscle function with MyoStrain, which Prenuvo says doesn't diagnose heart disease or blocked arteries; select markets) and Body Composition Analysis. Prenuvo also sells these as stand-alone add-ons.
- Ezra Skeletal and Neurological ($3,999) adds the spine, hip and knee assessment, a head and neck MR angiogram, brain analysis including "brain age", and body composition, over two sessions. Against Prenuvo Executive at the same price, it covers the hips, thighs and knees but not the chest or lower legs.
- Ezra's CT add-ons are the one thing Prenuvo doesn't offer. A Heart CT gives a coronary calcium score (ages 35–85; not for people with stents, a pacemaker, prior bypass or known heart disease), and a Lung CT looks for nodules (Ezra doesn't recommend it under 40). Both use a low dose of radiation. A calcium score is a guideline-recognized heart test, and many local hospitals and imaging centers offer one, often for less.
Who reads it, and what happens after
| Step | Prenuvo | Ezra |
|---|---|---|
| Where | Its own clinics, its own staff, identical machines (Prenuvo's description) | Partner centers (RadNet, Lenox Hill Radiology, RAYUS and SimonMed are named in customer accounts); "mostly closed wide-bore MRI", one open MRI in the network |
| Reads the images | Prenuvo Medical Group radiologists; Prenuvo says its medical group has "200+ healthcare professionals" (clinical mission) | A board-certified radiologist specializing in the body region |
| Report | Organized by body system, findings ranked by urgency | Ezra Report with a 1-to-5 risk score per finding; AI turns the radiology report into plain language |
| Results conversation | A 20-minute phone call with a nurse practitioner or physician (40-minute video for Executive); Comprehensive and Executive add a second review after 6-month labs | Not mentioned on Ezra's site. Ezra offered a video consultation in 2024 (GeekWire); a 2026 reviewer couldn't reach a person |
| Urgent findings | A provider calls you | "Your Ezra Medical Provider directly contacts you" |
| Follow-up tests and referrals | Not ordered by Prenuvo; your doctor's job | "We don't directly connect or refer our patients to further imaging or tests" |
| Comparing scans over time | Later Prenuvo scans compared with earlier ones | Recommends a scan every 12 months to compare; one customer's report referenced their earlier scans at the same partner center |
What that means for you. With either company, anything the scan flags becomes your own doctor's job, and usually your insurer's bill. Have a doctor lined up before you book.
About Ezra's AI. Ezra Flash is FDA-cleared (510(k) K230264 in April 2023 and K242334 in January 2025, for head, abdomen and pelvis MRI) to reduce image noise, which is what lets a faster scan stay readable. The clearance is for image enhancement, not for detecting cancer. A radiologist still reads the scan, per Ezra's FAQ.
The evidence, briefly
The research is about whole-body MRI in general, not about either company's scan. Our Prenuvo deep dive covers it in full; in short:
- Cancers found: about 1 to 2 per 100 people scanned without symptoms. An independent 2025 meta-analysis of 10 studies and 9,024 people found confirmed cancer in 1.57% and concluded that the evidence doesn't support routine whole-body MRI for people without symptoms (European Radiology, 2025; Diagnostic Imaging report).
- Other findings: almost everyone has some finding, and about 30% of people in published studies need further evaluation (Zugni et al., 2020).
- Living longer: not shown. No trial has tested it, and the American College of Radiology doesn't recommend total-body screening for people without symptoms, risk factors or family history (ACR, 2023).
- Shorter vs longer scans: we found no study comparing a 22-minute protocol with a 50-minute one, or comparing Prenuvo's and Ezra's accuracy.
The companies' own numbers
| Claim | What it counts | Independent? |
|---|---|---|
| Prenuvo: "1 in 20 scans result in a potentially life-saving diagnosis" (homepage) | 5% of scans, "based on our internal data analysis", mainly radiologist-suspected cancer or pre-cancer findings and brain aneurysms | No |
| Ezra: "Ezra has helped 6% of our members identify potential cancer" (homepage) | No time period, total or definition given | No |
| Pooled research: 1.57% | Confirmed cancers in 9,024 people without symptoms, across 10 studies | Yes |
"Potentially life-saving" and "potential cancer" aren't the same as a confirmed cancer, and neither company publishes how many of its flagged findings turned out to be cancer. Prenuvo's own study (Polaris, 1,011 people at one clinic) reported 2.2% with biopsy-confirmed cancer; it was presented at a conference, and we found no full journal paper. We found no published study of Ezra's results.
What each costs over five years
Paying every year at today's prices, five years of Prenuvo's Comprehensive membership costs $12,495, and five years of Ezra's MRI with Spine plus a Function membership costs $9,320. Figures are US dollars before any follow-up tests, assuming prices don't change.

The fairest pairing
Prenuvo Comprehensive against Ezra MRI with Spine plus a Function membership. Both include the spine, a broad blood panel and a repeat blood draw within the year.
Whole Body Scan (head to ankle, including the chest), a Comprehensive blood panel, follow-up labs at 6 months, and two results reviews with a clinician.
The 47-minute scan (no chest or legs), Function's 100+ test annual draw plus its 60+ test retest, and Function's written clinician summary. No results conversation is mentioned for the scan.
The $635 a year gap ($3,175 over five years) buys more of the body scanned and two clinician conversations with Prenuvo. The Ezra route buys the larger published blood panel (see our Function Health deep dive) and Ezra's wider choice of locations.

Not in the table
- Follow-up imaging, specialist visits and biopsies, through your own doctor and insurance
- Prenuvo's Executive price may be higher in New York City ($4,499 when we checked on Nov 5; not shown on Nov 9)
- Travel: Prenuvo has 24 US sites; Ezra's partner centers are in many more cities
- Guideline screening neither scan replaces
Price history. Ezra launched its 22-minute scan in May 2025 at $499, marketed through Function; that was a launch price, and the scan is now $999 ($899 for members). Before the Function deal, Ezra's full-body scans cost $1,350 to $2,500 (GeekWire, Aug 2024). Prenuvo's full-body scan has cost about $2,500 since at least 2023; its strike-through figures beside today's prices ($1,329, $3,099, $5,897) are Prenuvo's own comparisons, not previous prices we verified.

Who's behind each company
- Prenuvo was founded in 2018 and is independent. Its homepage says it is "trusted by more than 200,000 patients" (Prenuvo, Nov 2026). It is sponsoring Project Hercules, a 10-year study of up to 100,000 people near Boston; its Boston clinic scans only study participants.
- Ezra was founded in New York in 2018 by Emi Gal (still CEO) and Diego Cantor. It raised about $43 million from investors including FirstMark, Accomplice and Credo Ventures (AlleyWatch) before Function Health bought it in May 2025, for an undisclosed sum. It launched prostate MRI screening in 2019, received an FDA clearance for prostate-analysis AI in 2020 (Ezra release), and has worked with RadNet from the start. At the acquisition it had "nearly 100" US locations; it now lists 170+.
- The rivalry. Prenuvo publishes a page called "Setting the record straight about Ezra", which says Ezra employs no full-time radiologists, owns no facilities and has published no efficacy study. Those are a competitor's claims. The facility point matches Ezra's own FAQ (partner centers); we couldn't check the staffing claim.
Hands-on reviewers
| Source | Scan | Who paid | What they found |
|---|---|---|---|
| Paul von Zielbauer, AGING with STRENGTH Aug 2026 | Both, 8 days apart in May 2026: Ezra with spine ($1,649, at a RadNet center; Ezra lists $1,699 today, and he doesn't say why he paid less) and Prenuvo ($2,099 after a $400 holiday discount) | Funded, not free from either company: an entrepreneur outside health care, whom he doesn't name, paid for both scans and for his time. He says the funder set no conditions and never contacted him | The two reports differed: Prenuvo found six disc herniations Ezra didn't report; Ezra flagged pituitary and prostate findings Prenuvo didn't; both found kidney cysts of different sizes. Ezra's report had a dictation error that stood for 12 days, and he couldn't reach a person. Prenuvo gave a 45-minute nurse practitioner consultation. His view: neither is truly full-body, Prenuvo's experience and follow-up were better, and a healthy person probably doesn't need either |
| Taylor Soper, GeekWire Aug 2024 | Ezra, the older 60-minute scan | Ezra (disclosed) | One "3" (non-urgent follow-up) finding, which his own doctor decided needed nothing more. Ezra offered a video consultation then. His view: likely not needed for healthy adults, and "too much uncertainty" for yearly scans for everyone |

What customers say
Trustpilot: Prenuvo 2.4 from 13 reviews (Nov 5, 2026); Ezra's profile has no reviews and is unclaimed (Nov 9, 2026). Too few to rely on either way.
Reddit: we counted every person who said they'd had an Ezra scan, in 7 threads from 2023 to 2026 (6 had Ezra customers). For Prenuvo we use the 18 accounts coded for our Prenuvo deep dive. These are small, self-selected samples, not satisfaction rates.

Three things skew the Ezra sample
- Two threads are on r/Function_Health, which is moderated by official Function accounts, so members are well represented.
- One thread, "Terrible Ezra Experience", drew 5 people with the same complaint. That tells you the problem happened, not how often.
- Two of the positive accounts describe Ezra's older 45–60 minute scan from 2021 to 2024. Of the 11 accounts of Ezra since 2025, 2 were positive, 3 mixed, 5 negative and 1 had no results yet.
| Theme | Prenuvo | Ezra |
|---|---|---|
| Pleasant visit, comfortable scanner | Several | Several, including branded pajamas and a mirror headset |
| Results time | Next day to five weeks across sources | 7 to 12 days in accounts; one over three weeks |
| A report that missed or misdescribed something already known | 3 in our sample (a torn tendon and a recent shoulder repair; a thyroid finding a later CT showed) | 2 (a removed gallbladder reported as "normal"; spine findings another MRI had shown) |
| A finding later ruled out, after more tests | 3 | 1, secondhand (a prostate spot; follow-up MRI clear) |
| Heart CT couldn't be scored; refund took repeated emails | Not applicable | 5, all in one complaint thread (late 2025) |
| Booking or scheduling problems | Cancellations and rescheduling (Trustpilot) | A CT booked at a center with no CT technologist; one center closed on arrival (no scan) |
| A results conversation | Reported as included | Before 2025, an Ezra doctor called. Since: not reported |
| Had both | 1 Reddit user: Prenuvo "great ... night and day compared to Ezra" | |
Accounts are self-reported and unverified. Some "missed" findings may be outside what the scan covers (the Ezra Annual MRI doesn't include the spine, and whole-body sequences aren't designed to assess joints and tendons) rather than reading errors; we can't tell which.

FAQ
Is Ezra cheaper than Prenuvo?
Yes, but for less of the body. As of November 2026, Ezra's $999 Annual MRI leaves out the spine, chest, arms and legs. With the spine, Ezra costs $1,699 ($1,499 for Function members), against $2,499 for Prenuvo's Whole Body Scan.
Is Ezra as good as Prenuvo?
No study compares them. In November 2026 Prenuvo's Whole Body Scan covers more of the body (about 50 minutes, head to ankle) than any Ezra scan, and Prenuvo includes a results call; Ezra costs less and has many more locations. Which matters more depends on what you want scanned and whether you have a doctor to review the report.
Is Ezra owned by Function Health?
Yes. Function Health bought Ezra in May 2025, for an undisclosed sum. Ezra still sells scans under its own name to anyone, and Function members pay $100 to $200 less.
What's the cheapest full-body MRI from Prenuvo or Ezra?
Ezra's Annual MRI at $999 ($899 for Function members), as of November 2026. It isn't head to toe: it covers the head, neck, abdomen and pelvis. Prenuvo's cheapest is the Core membership at $1,199, with a 25-minute Focused Scan from head to mid-thigh.
What does Reddit say about Prenuvo vs Ezra?
In the threads BML read in November 2026, 13 people said they'd had an Ezra scan: 4 positive, 3 mixed, 5 negative and 1 still waiting for results. Of 18 Prenuvo customers BML coded earlier, 9 were positive, 2 mixed and 5 negative. Both are small, self-selected samples; the one Reddit user who'd had both preferred Prenuvo.
Is a 22-minute MRI as good as a 50-minute one?
No study we found compares them. Ezra's faster scan relies on FDA-cleared software that reduces image noise; Prenuvo says longer scans collect more image data. Neither company has published a head-to-head of accuracy.
Which finds more cancers?
Unknown. Prenuvo says 5% of its scans find something "potentially life-saving" and Ezra says 6% of members found "potential cancer", but both are the companies' own figures with their own definitions. Independent research finds confirmed cancer in about 1.6% of people scanned.
Do Prenuvo or Ezra use contrast dye?
Prenuvo says its screening scans are done "completely without IV-contrast". Ezra's FAQ doesn't say for its standard scans, and customers and a 2024 GeekWire review describe no injection.
Who can't have a Prenuvo or Ezra scan?
Both are for adults 18 and over and don't scan during pregnancy. Prenuvo can't scan people with pacemakers and reviews other implants by device model; Ezra reviews implants and non-removable metal case by case. Prenuvo uses 70 cm wide-bore scanners; Ezra's partners use mostly closed, wide-bore machines, with one open MRI.
How soon can I book?
Prenuvo says it can usually book flexible patients within 1 to 2 weeks. Ezra doesn't say; one customer in 2025 waited about a month.
Can I get a calcium score with either?
Only Ezra sells one, as a $349 CT add-on. Prenuvo's heart add-on measures heart-muscle function, not plaque. A calcium score is also widely available from hospitals and imaging centers.
Are they covered by insurance or HSA/FSA?
Neither is covered by insurance. Both say HSA/FSA may apply; check with your plan administrator.
What happens if something is found?
Neither company orders follow-up tests or refers you to specialists. You take the report to your own doctor.
Method, sources and updates
Method. We read each company's pricing, FAQ, locations and terms pages on November 9, 2026, in a browser where pages load content with scripts, and both companies' privacy policies. FDA clearances were checked in the FDA's 510(k) database. The evidence comes from the same independent sources as our Prenuvo deep dive, plus searches for any study of Ezra's results (none found). For Reddit, we read 7 threads about Ezra or Prenuvo from 2023 to 2026 and counted each person who said they'd had an Ezra scan once, recording their overall view as positive, mixed, negative or no view; we left out staff, clinicians, people who hadn't had a scan and secondhand stories, and we don't publish usernames. We didn't have either scan and didn't contact either company. This page was drafted with Claude, an AI tool, and its figures were checked against the sources below on the dates shown.
