Full-body MRI and preventive scan tourism: Neko vs Ezra vs Prenuvo vs Human Longevity Inc. compared

What preventive scan tourism actually is

Five years ago, "diagnostic tourism" meant flying to Bangkok for a cheap executive physical. The 2026 version is different. Four VC-backed operators have built consumer-friendly preventive imaging around MRI and, in one case, a combination of thermal cameras, lasers and ECG. Each has a different thesis about what catches disease early, at what price point, and with how much human oversight. The result is a small but growing category of travellers flying specifically for a scan — sometimes combined with a stay, sometimes as a same-day round trip from a secondary home city.

The numbers matter before the commentary. Neko Health currently charges £299 per scan in the UK, with a New York launch planned for spring 2026 at an as-yet-undisclosed US price Bloomberg reports will be higher. Ezra's scans run $1,350 to $2,500 depending on coverage. Prenuvo has restructured around annual memberships, with a $1,199 core tier, a $2,499 comprehensive tier, and an executive tier at roughly $5,000. Human Longevity Inc.'s concierge 100-Plus programme sits at a different altitude entirely — approximately $25,000 per visit, with depth to match.

None of the four is covered by standard health insurance in the US, UK, Canada, or most of Europe. All four argue they find serious conditions early; each has anecdotal cases to cite. The medical establishment, as we'll come to, is not uniformly convinced.

The four providers worth flying for

There are dozens of local imaging centres that will sell you a preventive MRI. I am covering four specifically because each has built consumer infrastructure — scheduling, standardised protocols, plain-English reporting — that makes them viable as a travel destination rather than a local appointment.

Neko Health — the £299 disruptor

Founded by Spotify co-founder Daniel Ek and Hjalmar Nilsonne, Neko has the most distinctive approach of the four. It is not a whole-body MRI at all. The Neko Body Scan uses 70-plus sensors — thermal cameras, 3D cameras, ECG, lasers and finger sensors — to capture 50 million data points in about 15 minutes, followed by an unrushed consultation with a Neko doctor who walks through the results in real time.

The price is the story. At £299 in the UK and approximately £400 (≈$500 USD) in the planned US centres, Neko costs a fraction of an MRI-based full-body scan. That has two consequences. First, it makes annual repeat scanning genuinely affordable, which Neko argues — correctly — is the real value: what you want is trends over time, not a single snapshot. Second, it means the scan catches a different set of things. Neko is designed to detect skin cancers, atrial fibrillation, aortic aneurysms, diabetes, and cardiovascular risk markers. It is not looking inside organs the way an MRI does.

What Neko catches and what it doesn't

Neko's own first-year data, covering 2,707 scans from February to December 2023, found 78.5% of guests had no significant findings, 14.1% required medical treatment, and about 1% received potentially life-saving interventions for cardiovascular, metabolic or skin conditions. Independent analyses of the same data note that the 1% life-saving figure is impressive but comes from a self-selected, health-conscious clientele, which inflates the base rate compared to a random population.

What Neko does not do is look for tumours in the liver, pancreas, kidneys, brain or spine. That is what Prenuvo, Ezra and HLI are for.

Who Neko is right for

Readers who want an annual high-signal cardiovascular and metabolic screen at a price point that supports repeat scanning — and who separately have whatever cancer screening their age and family history warrant through normal medical channels. At £299 a year it is also a good complement to a more expensive full-body MRI done every two or three years.

Where to scan

London, Manchester, Birmingham and Stockholm are open as of April 2026. The New York centre launches in spring 2026 subject to regulatory approval. Over 300,000 people were on the waitlist globally as of early 2026, so book well ahead.

Prenuvo — the whole-body MRI standard

Prenuvo is the company that put the Kim Kardashian Instagram post into the news cycle, but the operational reality is more substantive than the celebrity marketing. Prenuvo owns and operates its own imaging facilities across 21 US clinic locations, runs its own MRI protocols, and has built out a medical group of over 100 licensed providers including 80-plus board-certified radiologists.

The 2026 pricing restructure moved Prenuvo from single-scan to annual membership:

• Core ($1,199/year): focused MRI plus lab panel assessment. Head-to-mid-thigh scan; arms, spine and aneurysm assessment not included.
• Comprehensive ($2,499/year): full whole-body MRI plus detailed lab panels.
• Executive (approximately $5,000/year): whole-body MRI, brain health assessment, body composition analysis, and expanded lab panel.

The membership structure reflects Prenuvo's core thesis: whole-body MRI is most valuable as active surveillance over time, not a single snapshot. A scan now that establishes your baseline is worth more if repeated in 12 months than if treated as a one-off.

What Prenuvo catches

Prenuvo publicly claims the scan can potentially detect more than 500 conditions including early-stage tumours, aneurysms, muscle tears, appendicitis and fatty liver. The company's published data suggests roughly 1 in 20 scans result in a potentially life-saving diagnosis, though this figure, like most in the category, comes from a self-selected health-conscious clientele.

Where Prenuvo is strongest

Facility control is the real differentiator. Because Prenuvo owns its imaging centres and hires its own technologists, image quality and patient experience are more standardised across locations than they are with a network model. The medical governance — physician leadership trained at Johns Hopkins, Stanford, Medical College of Georgia — is deeper than any of the four providers except HLI.

Ezra — the AI-accelerated network

Ezra, founded in 2018 by Emi Gal, has scaled faster than Prenuvo but through a different model. Rather than owning facilities, Ezra partners with ACR-accredited imaging centres across 60-plus US clinic locations in nine states, bringing its own protocols, AIs and radiology report templates to those facilities.

The pricing tiers are simpler than Prenuvo's:

• Ezra Flash (30 min, from $1,350): AI-accelerated abbreviated scan. The AI, called Ezra Flash, removes noise from single-capture MRI so a scan that used to take 60 minutes finishes in half the time.
• Ezra Full Body (60 min, $1,950): the standard scan covering head, neck, spine, abdomen and pelvis.
• Ezra Full Body Plus ($2,350–$2,500): adds low-dose chest CT and coronary calcium scoring, which picks up lung cancer risk and cardiovascular calcification that MRI does not cover well.

What Ezra catches

Ezra publishes data suggesting approximately 6% of its members identify potential cancer early through the scan, and that nearly 5% have a highly suspicious finding for cancer requiring additional follow-up. The AI stack is genuinely useful on the reporting side: Ezra Reporter translates radiology jargon into plain English, and the findings are ranked 1–5 for severity with colour coding.

The honest criticism

Prenuvo has aggressively positioned against Ezra on the grounds that Ezra does not employ any full-time radiologists (outsourcing to third-party radiologists across partner imaging centres) and that Ezra's chief medical officer is not a radiologist. Ezra responds that each Full Body Plus scan is analysed by three specialist radiologists — neuro, body and CT — and that the network-partner model gives wider geographic coverage than Prenuvo's owned-facility model. Both are true. Pick the argument that matters more to you.

Human Longevity Inc. — the concierge option

Human Longevity Inc. (HLI), founded by J. Craig Venter in 2013, operates at a different altitude entirely. The 100-Plus programme combines whole-body MRI, whole genome sequencing, advanced cardiac imaging, cognitive assessment, metabolomics, microbiome analysis and a physician consultation that runs several hours — all in a single visit to the San Diego facility.

The price reflects that depth. The full annual 100-Plus programme starts at approximately $25,000 per visit, with more comprehensive tiers extending beyond that. Memberships for ongoing monitoring layer on top.

What HLI catches that the others don't

Genome sequencing is the distinctive addition. HLI will tell you your BRCA status, polygenic risk scores for common diseases, pharmacogenomic sensitivities, and rare variant status — data that is clinically actionable in a way a scan alone is not. The cardiac imaging, including coronary CT angiography alongside the MRI, is more comprehensive than anything Ezra or Prenuvo offers. The trade-off is the price and the single-location constraint.

Who flies for HLI

Readers with serious family history of cancer or cardiac disease, executives whose companies cover executive physicals at this tier, and patients who want the one-visit comprehensive baseline rather than the annual-membership approach. The facility is in San Diego; the majority of visitors fly in specifically, stay one or two nights, and combine the visit with a La Jolla hotel stay.

Side-by-side comparison

The medical community's honest objections — and what they're missing

Any honest guide has to name the criticism. The American College of Radiology has a longstanding position that whole-body MRI screening is not cost-efficient or effective at prolonging life for asymptomatic patients, and that such procedures will "lead to the identification of numerous nonspecific findings that will not ultimately improve patients' health but will result in unnecessary follow-up testing and procedures, as well as significant expense." The American College of Preventive Medicine makes a similar case.

The objection boils down to false positives. A scan that flags something suspicious in an otherwise healthy patient kicks off biopsies, repeat imaging, anxiety, and occasionally surgery — all for a finding that was never going to become clinically significant. Ezra itself reports roughly 5% of scans produce a highly suspicious cancer finding requiring follow-up. Most of those turn out to be benign. The psychological cost and downstream medical cost of the workup is not zero.

The counter-argument, articulated well by Ezra's chief scientist Daniel Sodickson of NYU, is that active surveillance with repeat scans is already standard in higher-risk populations — prostate cancer, breast cancer, patients with known genetic risk — and the real question is how to extend the safety net to lower-risk patients while controlling false-positive rates. The providers are investing heavily in AI-driven false-positive reduction and in plain-English reporting that helps patients distinguish "watch and wait" from "act now."

Where the debate currently sits: the scans are most defensible for patients with family history, known genetic risk, specific symptoms, or age-related baseline establishment. They are least defensible as generic wellness spending for low-risk patients with no specific concern.

When is a scan worth flying for?

Five situations genuinely justify flying for one of these scans.

One, family history of cancer. If a first-degree relative had pancreatic, ovarian, or early-onset colon or breast cancer, the economics of early detection shift. Whole-body MRI is defensible as a surveillance layer alongside whatever screening your family-history-specific protocol already involves.

Two, known genetic risk. BRCA1/2, Lynch syndrome, Li-Fraumeni, and other high-penetrance mutations warrant enhanced surveillance. HLI in particular combines genome sequencing with imaging in a way that suits this reader profile.

Three, establishing a baseline at 40 or 50. A scan now, establishing what your organs look like before any disease develops, makes every subsequent scan — whether at the same provider or elsewhere — more informative. Prenuvo's membership model is built around this thesis.

Four, executive physical as an annual discipline. Readers whose companies cover this tier of screening tend to book HLI or Prenuvo Executive annually. The value is as much in the forcing function of an annual baseline as it is in any specific finding.

Five, a specific unresolved concern. Vague symptoms that your GP has not been able to explain, a suspicious family pattern, or a personal history that warrants a broader look than standard screening provides. This is the category where the scan most often returns genuinely actionable information.

Situations where you are probably wasting money: generic wellness spending, someone on Instagram said so, you saw Kim Kardashian post about it, or you have no specific concern and no family history. In those cases the money is probably better spent on a proper executive physical with a physician who knows you.

Logistics — booking, flights, what to bring

Booking lead time

Neko is waitlist-driven; budget two to four months for a first-time scan in London or Stockholm, longer for New York at launch. Prenuvo and Ezra can usually accommodate within two to four weeks. HLI books two to four months ahead given the programme length and physician availability.

Flights and accommodation

For US-based readers, Ezra's 60-plus locations mean you rarely need to fly for it; a direct drive from a neighbouring city is often simpler. Prenuvo's 21 locations require more selection — its Manhattan, LA, San Francisco, Miami and Toronto sites are the best-organised for out-of-town visitors. For Neko, a UK or Stockholm trip doubles as a city weekend; for HLI, a La Jolla stay (the Lodge at Torrey Pines, Park Hyatt Aviara, or a short list of private rentals in the area) is the natural companion.

For transatlantic visitors combining a Neko scan with a London weekend, or for a US-based reader flying to San Diego for HLI, private charter is disproportionately worthwhile given the time compression around the scan windows and the occasional same-day turnaround on results. The schedule flexibility matters more than the price.

Medical records

Bring recent bloods, GP notes, any specialist records relevant to what prompted the scan, and a list of current medications. Prenuvo and HLI will ask for these at intake; Ezra's short medical questionnaire is less comprehensive but your results interpretation improves if the radiologist has the clinical context.

Insurance and evacuation

The scan itself is almost never insurance-reimbursable. Travel health cover for the trip is a separate and useful layer; SafetyWing is the default for the international members of this readership. If a scan flags something requiring immediate follow-up in a country other than your own, medical evacuation cover becomes meaningful in a way it was not the week before.

Ground transfer

Most of these centres sit in city locations where a standard car service is fine, but the pre-scan fast and post-scan fatigue argue for a pre-booked transfer rather than a ride-share. GetTransfer runs luxury-tier service across London, New York, LA, Miami and San Diego.

The bottom line

If you have family history, genetic risk, or a specific concern, one of these four scans is worth doing. Pick the provider whose model suits your situation:

• Neko Health if you want annual cardiovascular and metabolic screening at a price that supports repeat scanning.
• Prenuvo if you want the best-governed whole-body MRI with owned facilities and institutional radiology.
• Ezra if you want MRI with optional CT and coronary calcium scoring, and geographic convenience matters.
• HLI if you want the single deepest one-visit baseline that combines imaging with genome sequencing and physician depth.

If you are in the "generic wellness spending" bucket, the most honest answer is to spend the money on an executive physical with a physician who knows you. A scan is a snapshot. A relationship with a doctor who will still be there next year is what actually catches problems. The readers who get the most out of these providers are the ones combining them with that relationship — not replacing it.
