Function Health / Ezra Review

Function Health / Ezra Review Updated March 2026

This Ezra review covers the healthcare technology company founded in 2018 by Emi Gal and acquired by Function Health in May 2025. They focus on early cancer detection through full-body MRI (magnetic resonance imaging) screening and artificial intelligence. Unlike traditional healthcare providers that use reactive diagnostic approaches, Ezra offers proactive scanning services designed to detect potential cancers and abnormalities before symptoms appear. The company positions itself at the intersection of advanced medical imaging and AI-powered analysis to make comprehensive cancer screening more accessible and affordable.

The acquisition by Function Health — a lab testing platform offering 160+ biomarker tests for $365/year — represents a significant strategic shift. Ezra now operates as a subsidiary of Function, with founder Emi Gal continuing to lead the business. Together, the combined platform aims to deliver both comprehensive imaging and blood-based lab testing under one membership, creating what the companies call “the new standard of care.”

What’s New Since Our Last Review

The biggest changes since our original review are worth calling out up front:

Function Health acquired Ezra in May 2025, integrating imaging with Function’s lab testing platform
Scan time dropped from 60 minutes to 22 minutes, enabled by FDA-cleared AI image enhancement
Entry-level scan price dropped from ~$1,500 to $899 for Function members (previously advertised as $499 at launch, currently listed at $899 with a $365/year Function membership required)
Availability expanded to nearly 100 U.S. locations, with plans to exceed 1,000
Three AI systems are now active: Ezra Flash (image enhancement), Ezra Assist (radiologist support, FDA-cleared for prostate), and Ezra Reporter (plain-English translation of radiology reports)
A 15-minute scan for ~$500 is a stated 2026 goal, with the February 2025 FDA clearance for Ezra Flash cited as a key step toward that target

Key Offerings

Function Membership + Ezra Scans

Ezra’s services are now accessed primarily through a Function Health membership, which costs $365/year and includes 160+ lab tests. Scans are billed separately, with member pricing applied automatically at checkout via Ezra’s booking portal.

Current scan options for Function members include:

MRI Scan: Full body (head, neck, abdomen, pelvis) — screens for hundreds of conditions including cancers of the brain, thyroid, liver, gallbladder, pancreas, spleen, kidneys, adrenal glands, bladder, ovaries, uterus, and prostate. Also checks for stroke signs, sinus inflammation, fatty liver disease, uterine fibroids, and abdominal aortic aneurysm. Takes as little as 22 minutes. $899 for Function members.
MRI Scan with Spine: Everything above plus targeted spine coverage — herniated discs, spinal lesions and tumors, cervical spinal stenosis, scoliosis, fractures, and degenerative changes.
MRI Scan with Spine + Neuro: Adds neurodegeneration screening, brain age analysis, and artery narrowing assessment in the head and neck.
MRI Full Body Ultimate: The most advanced tier — adds body composition (fat and muscle volume), hip evaluation (labrum, cartilage, joint health), and knee scans.
Heart CT Scan: Uses low-dose computed tomography (CT) to assess coronary calcium and lung health. $349 for Function members.

Scans are not included with the base Function membership — they are add-ons. Both the membership and imaging costs are HSA/FSA (health savings account/flexible spending account) eligible.

For those who want imaging without joining Function, direct booking through Ezra’s website remains available, though member pricing will not apply.

The Three-AI Stack

A key differentiator for Ezra post-acquisition is its layered AI approach, which Gal describes as “stacking AIs” to reduce cost and pass savings to the consumer:

Ezra Flash: An FDA-cleared Class II medical device that enhances MRI image quality acquired at faster speeds. Rather than scanning multiple times to reduce noise (as traditional MRI requires), Flash scans once and uses AI to remove noise algorithmically. This is the primary driver of the 22-minute scan time. A February 2025 FDA clearance expanded Flash’s capabilities from neuro imaging to the abdomen and pelvis — covering the full body.

Ezra Assist: AI-assisted analysis that helps radiologists identify areas of concern in MRI scans. Currently FDA-cleared for prostate MRI. All scans are still reviewed by board-certified radiologists.

Ezra Reporter: Translates radiology reports from clinical terminology into plain English, making findings accessible to members without a medical background.

Science and Validity

Ezra’s approach builds on established medical imaging technologies, with several meaningful innovations layered on top:

Strengths:

MRI is a well-validated, non-invasive imaging technology with no ionizing radiation
Board-certified radiologists review every scan
Ezra Flash AI has received FDA 510(k) clearance for both neuro and abdominal/pelvic imaging
Approximately 6% of scanned Ezra members have identified potential cancer, per company data
Annual scanning enables longitudinal comparison — catching subtle changes over time that a one-off scan would miss

Limitations:

Full-body MRI for cancer screening has not been established as a standard of care by any major medical association
False positives remain a real concern — Ezra reports roughly 5% of clients have a highly suspicious finding requiring additional follow-up
Limited long-term outcomes data on whole-body screening in asymptomatic populations
Not designed to replace age-appropriate, evidence-based cancer screenings (mammography, colonoscopy, etc.)
Some cancers are better detected by modalities other than MRI

Pricing and Value

Current pricing structure (as of early 2026):

Item	Cost
Function Health membership	$365/year
MRI Scan (Full Body, 22 min)	$899 (member price)
Heart CT Scan	$349 (member price)
MRI with Spine	Higher tier — see functionhealth.com
MRI Full Body Ultimate	Higher tier — see functionhealth.com

A note on pricing transparency: at launch in May 2025, the scan was widely advertised at $499. Current member pricing on Function’s website lists the base MRI at $899. Prices may continue to evolve as the companies integrate and expand — always check functionhealth.com/scans for current pricing.

Insurance does not cover these scans, as they are considered preventive rather than diagnostic. The all-in cost of membership plus a base MRI scan starts at approximately $1,264/year — significantly less than Ezra’s pre-acquisition prices, but still a meaningful out-of-pocket commitment.

Member Experience

Booking Process

Join Function Health at functionhealth.com ($365/year)
Complete lab testing at any of 2,000+ Quest Diagnostics locations (must be done before scanning)
Access your Ezra booking link from the Function dashboard — member pricing is applied automatically
Schedule your scan at a nearby partner imaging facility
Receive results via your Ezra account within 7–10 business days
Review findings in plain English via Ezra Reporter, then consult with a medical provider on next steps

Function and Ezra are actively working to consolidate results into a single Function dashboard, but as of early 2026 imaging results are still delivered through a separate Ezra account.

Availability

Ezra partners with existing imaging centers rather than operating its own facilities. At launch of the Function acquisition, scans were available at nearly 100 U.S. locations, with plans to expand to 1,000+. Availability varies significantly by region — urban areas are well covered, while rural access remains limited. Check functionhealth.com/scans for locations near you.

Strengths

Non-invasive with no radiation exposure (MRI scans)
Dramatically reduced scan time (22 minutes vs. 60 minutes pre-acquisition)
Three-layer FDA-cleared AI stack improving speed, detection, and report readability
Annual scanning enables longitudinal health tracking
Integration with Function’s 160+ lab tests creates a more complete health picture
HSA/FSA eligible
Emi Gal continues to lead Ezra, maintaining continuity of the core product vision

Limitations

Still a significant cost barrier ($365 membership + $899+ scan = $1,264+ minimum annually)
No insurance coverage
Limited rural availability
Not a replacement for standard-of-care cancer screenings
False positives can trigger anxiety and unnecessary follow-up procedures
Imaging and lab results still siloed across two platforms (integration in progress)
No major medical society endorsement for asymptomatic whole-body MRI screening

Comparison to Competitors

Compared to Prenuvo: Ezra’s key advantage post-acquisition is price — Prenuvo’s flagship scan runs ~$2,500, compared to Ezra’s $899 member-priced MRI. Prenuvo has raised significantly more capital ($120M Series B closed February 2025) and recently added blood testing to its platform, mirroring Ezra/Function’s integrated approach from the other direction. Both companies target the same affluent, health-conscious demographic.

Compared to Fountain Life: Fountain Life offers a more comprehensive assessment — cardiovascular, genomic, and advanced biomarker testing alongside imaging — but at a substantially higher price point. Ezra/Function is a more accessible entry point into preventive imaging; Fountain Life remains the more thorough (and expensive) offering.

Compared to Human Longevity: Human Longevity emphasizes genomic sequencing and personalized medicine more heavily. Ezra/Function is narrower in scope but significantly more affordable and now far more geographically accessible.

Compared to InsideTracker: Fundamentally different approaches — InsideTracker focuses on blood biomarker optimization; Ezra focuses on structural imaging for cancer and disease detection. These are complementary rather than competitive, and notably, Function’s lab testing platform now overlaps more directly with InsideTracker’s core offering.

Ideal User

Ezra/Function is most appropriate for:

Individuals with a family history of cancer seeking proactive annual monitoring
Health-conscious adults who want a baseline imaging record for future comparison
People who want integrated imaging + lab testing under one platform
Those with specific concerns about organs best visualized by MRI
Anyone who finds Prenuvo’s pricing prohibitive but still wants full-body imaging

Conclusion

The Function Health acquisition has materially changed Ezra’s value proposition. The reduction in scan time from 60 to 22 minutes — driven by genuine FDA-cleared AI innovation — removes one of the key practical barriers to annual screening. The pricing improvement is real, even if the all-in cost remains out of reach for most Americans.

The integration of imaging with Function’s lab testing is the more interesting long-term story. A platform that combines structural imaging (what’s growing where) with comprehensive biomarker data (what’s happening metabolically) is genuinely closer to a “complete health picture” than either offering alone. Whether the AI will eventually become predictive — catching disease before it appears — remains to be seen, but the longitudinal dataset they’re building has real scientific value.

The caveats remain what they’ve always been: no major medical society recommends whole-body MRI for asymptomatic screening, false positives are a real and documented phenomenon, and the service still skews toward those who can afford $1,200+ per year in out-of-pocket preventive health spending. For those who can and understand the tradeoffs, it’s one of the more credible options in a space that is, frankly, rife with overclaiming.
