Four years ago nobody flew for a scan. In 2026 a specific audience does — HNW patients, people with family cancer histories, executives treating annual diagnostics as an insurance policy against the one thing money cannot fix. Here is what each provider delivers, what it costs, and which one actually fits you.

One thing worth sorting before you fly: if a scan flags something abroad, you want medical and evacuation cover already in place — the workup can start before you get home. SafetyWing covers exactly this for the international members of this readership.
See trip & medical cover →Neko (£299) is a multi-sensor cardiovascular and metabolic screen, not an MRI. Prenuvo ($1,199–$5,000/yr) is the best-governed whole-body MRI. Ezra ($1,350–$2,500) adds optional CT across the widest US network. HLI (~$25,000) is the single deepest one-visit baseline, combining imaging with whole-genome sequencing. They answer different questions — most readers with a genuine reason to screen want Neko annually plus a whole-body MRI every two or three years.
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, 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.
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 cases to cite. The medical establishment, as we’ll come to, is not uniformly convinced — which is exactly why matching the scan to your actual reason for screening matters more than picking the “best” one.
Not an MRI. 70+ sensors — thermal, 3D cameras, ECG, lasers, blood — capture 50 million data points, then a doctor walks you through the results live. Best-in-class for heart, metabolic and skin screening at a price you can repeat annually.
The best-governed whole-body MRI — 21 owned US clinics, 80+ board-certified radiologists, annual-membership model built around surveillance over time. The cancer-surveillance standard.
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) 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.
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 note the 1% life-saving figure comes from a self-selected, health-conscious clientele, which inflates the base rate versus 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.
London, Manchester, Birmingham and Stockholm are open as of mid-2026. The New York centre launches in 2026 subject to regulatory approval. Over 300,000 people were on the waitlist globally as of early 2026, so book well ahead. Neko’s London clinic is the flagship.
Prenuvo is the company behind the Kim Kardashian Instagram moment, 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 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:
The membership structure reflects Prenuvo’s thesis: whole-body MRI is most valuable as active surveillance over time, not a single snapshot. Facility control is the real differentiator — because Prenuvo owns its centres and hires its own technologists, image quality and patient experience are more standardised than a network model. Its published data suggests roughly 1 in 20 scans results in a potentially life-saving diagnosis, though that figure, like most in the category, comes from a self-selected clientele.
Partners with ACR-accredited centres across nine states, bringing its own AI and protocols. The Full Body Plus tier adds low-dose chest CT and coronary calcium scoring — lung and cardiac coverage MRI alone misses. Widest US footprint.
The deepest single-visit baseline: whole-body MRI, whole-genome sequencing, advanced cardiac imaging, cognitive and metabolomic assessment, hours of physician time. The only one that sequences your genome.
Ezra, founded in 2018 by Emi Gal, has scaled faster than Prenuvo 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 report templates. The tiers: Flash (30 min, from $1,350, AI-accelerated abbreviated scan); Full Body (60 min, $1,950, head-to-pelvis); and Full Body Plus ($2,350–$2,500, adds low-dose chest CT and coronary calcium scoring).
Ezra publishes data suggesting ~6% of members identify potential cancer early, and nearly 5% have a highly suspicious finding requiring follow-up. The honest criticism: Prenuvo positions against Ezra on the grounds that Ezra employs no full-time radiologists (outsourcing to third-party radiologists) and its CMO is not a radiologist. Ezra responds that each Full Body Plus scan is read by three specialists — neuro, body and CT — and the partner model gives wider geographic coverage. Both are true; pick the argument that matters more to you.
HLI, founded by J. Craig Venter in 2013, operates at a different altitude. The 100-Plus programme combines whole-body MRI, whole-genome sequencing, advanced cardiac imaging, cognitive assessment, metabolomics, microbiome analysis and a physician consultation running several hours — all in a single visit to the San Diego facility. The full annual programme starts at approximately $25,000 per visit.
Genome sequencing is the distinctive addition — BRCA status, polygenic risk scores, pharmacogenomic sensitivities, rare-variant status: data that is clinically actionable in a way a scan alone is not. The cardiac imaging (coronary CT angiography alongside MRI) is more comprehensive than anything Ezra or Prenuvo offers. The trade-off is price and the single-location constraint. Most visitors fly in, stay one or two nights, and combine the visit with a La Jolla stay.

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, warning 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 finding requiring follow-up; most turn out benign. The counter-argument, articulated by Ezra’s chief scientist Daniel Sodickson of NYU, is that active surveillance with repeat scans is already standard in higher-risk populations, and the real question is how to extend the safety net to lower-risk patients while controlling false-positive rates.
Where the debate sits: the scans are most defensible for patients with family history, known genetic risk, specific symptoms, or age-related baseline establishment, and least defensible as generic wellness spending for low-risk patients with no specific concern.
Five situations genuinely justify flying for one of these scans.
Situations where you are probably wasting money: generic wellness spending, someone on Instagram said so, or no specific concern and no family history. In those cases the money is better spent on a proper executive physical with a physician who knows you.
Neko is waitlist-driven; budget two to four months for a first scan, longer for New York at launch. Prenuvo and Ezra usually accommodate within two to four weeks. HLI books two to four months ahead given the programme length.
For Neko, a UK or Stockholm trip doubles as a city weekend. For HLI, a La Jolla stay is the natural companion — and for visitors who want a private home over a resort room for a one-or-two-night recovery stay, Plum Guide’s vetted La Jolla and San Diego homes suit the quiet post-scan window better than most hotels.
The scan itself is almost never insurance-reimbursable — but that is not the cover that matters here. If a scan flags something requiring immediate follow-up in a country other than your own, medical and evacuation cover becomes meaningful in a way it wasn’t the week before. For the international members of this readership, that layer is the genuinely worthwhile spend around a scan trip.
For US readers, Ezra’s 60-plus locations mean you rarely need to fly. For a tight scan window with same-day result turnaround — or a transatlantic Neko-plus-London weekend — private charter occasionally earns its place on schedule flexibility; our guide to longevity clinic and private-jet logistics covers when it’s justified. Pre-scan fasting and post-scan fatigue argue for a pre-booked transfer over a ride-share.
If you have family history, genetic risk, or a specific concern, one of these four scans is worth doing. Match the provider to your situation: Neko for affordable, repeatable annual cardiovascular and metabolic screening; Prenuvo for the best-governed whole-body MRI; Ezra for MRI plus optional CT and geographic convenience; HLI for the single deepest one-visit baseline with genome sequencing.
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 — and the readers who get the most out of these providers are the ones combining them with that relationship, not replacing it.
Neko uses external sensors — thermal imaging, 3D cameras, ECG, lasers, blood tests — to build a cardiovascular, metabolic and skin-cancer screen in about 15 minutes. It does not look inside your organs. Prenuvo and Ezra use magnetic resonance imaging to capture internal structures — brain, spine, liver, pancreas, kidneys, pelvis — and are designed to catch tumours and internal abnormalities MRI is good at finding. They answer different questions. The best pairing for many readers is an annual Neko scan plus a two- or three-yearly whole-body MRI.
Almost never, for preventive use. Whole-body MRI and preventive scanning are not currently recommended by most professional medical organisations for asymptomatic patients, so health insurance does not cover them outside of specific high-risk indications. FSA/HSA accounts can be used to pay in the US. A few extended health plans in the UK and Canada will reimburse specific components. Assume you are paying out of pocket and treat any reimbursement as a pleasant surprise.
Honestly, there is no single winner for all cancer types. Whole-body MRI (Prenuvo, Ezra, HLI) is best for soft-tissue tumours in the brain, spine, liver, kidneys, pancreas and pelvis. Low-dose chest CT — which Ezra Full Body Plus and HLI include but Prenuvo and Neko do not — is the gold standard for lung cancer screening. For certain cancers like colon cancer, endoscopy is still the reference standard and no whole-body scan replaces it. The best approach is to match the scan to your specific risk profile rather than assuming any single scan covers everything.
Ezra has publicly reported that approximately 5% of scans produce a finding highly suspicious for cancer that requires follow-up. Most of those turn out to be benign on workup. Prenuvo does not publish a directly comparable figure. The broader radiology literature suggests any whole-body scan will flag indeterminate findings in 10–40% of asymptomatic patients depending on age and body habitus — most resolve without intervention but the downstream tests, costs and anxiety are real. Patients who deal poorly with medical uncertainty may find the whole category psychologically counterproductive.
Depends on what you're trying to catch. If the concern is cardiovascular disease or you want an annual screen you can actually afford to repeat, Neko. If it's cancer surveillance and you want the best-governed MRI, Prenuvo Comprehensive. If you want imaging plus genome sequencing in a single deep baseline visit, HLI. If convenience and MRI-plus-CT together matter most, Ezra Full Body Plus. For a typical reader with no specific family history or genetic risk, Neko annually plus an every-two-years whole-body MRI at Prenuvo is a defensible long-term plan and the most cost-efficient.
For Neko, yes — there are only a handful of centres and the brand, protocols and doctor consultation quality are consistent in a way local scanning is not. For HLI, yes — the integrated programme does not exist elsewhere. For Prenuvo and Ezra, it depends on what is available locally. A Prenuvo-owned facility will generally deliver a more standardised experience than a local imaging centre doing ad-hoc full-body MRIs, but if you have a nearby Ezra partner facility with a strong radiology group the experience can be excellent. The travel cost is rarely the primary expense in this category, so the decision usually comes down to brand confidence rather than logistics.
The scan isn’t reimbursable, but the trip cover is the smart spend — medical and evacuation protection so that if a finding needs immediate follow-up abroad, the workup can start before you’re home.
