The whole-body MRI alternative to Prenuvo - now part of Function Health, with an entry scan from $499 in as little as 22 minutes via Ezra Flash AI.
Ezra is one of the two best-known names (alongside Prenuvo) in the consumer whole-body MRI market. As of the acquisition announced May 5, 2025, Ezra is part of Function Health and is sold through Function Health rather than as a standalone company. Same general protocol - full-body imaging, no contrast required, looking for incidental findings traditional preventive care misses.
The headline shift is price and speed. The entry full-body MRI now starts at $499, with the scan taking as little as 22 minutes using Ezra's Flash AI, and broader scans ranging up to roughly $3,999. That is a meaningfully lower entry point than Prenuvo's typical pricing, and it folds into the Function Health membership and lab ecosystem rather than a separate Ezra checkout.
The controversy that applies to both Ezra and Prenuvo: high false-positive rate. Catching incidental findings often generates worry that outweighs the actual clinical utility. Major medical societies don't endorse whole-body MRI as routine preventive screening. For buyers with personal or family cancer history, the math may favor it; for everyone else, it's a buyer-preference decision.
For longevity-focused buyers wanting whole-body imaging in their stack, Ezra (via Function Health) and Prenuvo are roughly comparable on protocol. The decision often comes down to price, scan speed, and which has scanners closer to your location.
Longevity-focused buyers wanting whole-body imaging at the lowest entry price ($499) and fastest scan. Function Health members folding imaging into their existing membership. People with family cancer history wanting comprehensive screening.
You're skeptical of the whole-body-MRI value proposition (high false-positive rate is real), or your insurance covers targeted imaging that addresses your specific risks.

Ezra (Function Health) Full Body MRI - buyer FAQ
Ezra vs Prenuvo - is there a meaningful difference?
Both are whole-body MRI scans, no contrast required, designed to surface incidental findings traditional preventive care misses. Ezra is now part of Function Health (acquired in an announcement dated May 5, 2025) and is sold through Function Health, with an entry full-body MRI from $499 and broader scans ranging up to roughly $3,999. Prenuvo typically runs higher for similar coverage. Ezra also leans on AI: its Flash AI can complete a scan in as little as 22 minutes, and AI-augmented radiologist reading is part of the workflow. Practical decision usually comes down to price, scan speed, and which has scanners closer to your location.
Should I actually do whole-body MRI screening?
Honest answer: depends on your risk profile. The published evidence on whole-body MRI as routine preventive screening is mixed - high false-positive rate (~15-30%) means many buyers end up doing follow-up imaging or biopsies on findings that turn out benign. For buyers with significant personal or family cancer history, the cost-benefit may favor scanning. For buyers without strong risk factors, the worry generated by incidental findings often outweighs the catch rate of clinically actionable disease.
How often should I repeat the scan?
Most longevity practitioners recommending whole-body MRI suggest annual or biannual cadence. The trend-tracking value (comparing this year's scan against last) often exceeds the single point-in-time finding value. Ezra (now via Function Health) and Prenuvo both offer membership / subscription options for buyers committing to annual cadence.
