Neko vs Prenuvo vs Ezra vs Human Longevity: which full-body scan is rational?

Full-body scans sell peace of mind. Sometimes they deliver it. Sometimes they start a cascade of incidental findings, follow-up imaging and anxiety. The rational buyer prices both outcomes before booking.

Answer-first

Neko is the best-priced low-radiation baseline, Prenuvo is the dedicated MRI brand, Ezra/Function is the aggressive value challenger, and Human Longevity is the executive-health package for buyers who want genomics, imaging and physician review in one day.

Agewell verdict

Worth considering for high-risk, high-agency buyers with a follow-up doctor. Weak for healthy low-risk buyers expecting proof of longer life.

The shortlist

Low-cost baseline

Neko Health

£299 / 2,750 SEK

Sensor, skin, cardiovascular and blood-marker baseline with doctor consult. Not a whole-body MRI.

MRI specialist

Prenuvo

from $1,199; whole body $2,499

The dedicated whole-body MRI brand with new membership positioning. Better if MRI is the product you actually want.

Value challenger

Ezra / Function Scans

$899-999 current pages; $499 launch claims

Fast AI-enhanced MRI with pricing that has moved publicly. Confirm live price before writing the recommendation.

Executive package

Human Longevity

$8,000+

Whole-body MRI, genome sequencing, 120+ biomarkers and physician review. Expensive, but coherent for the executive-health buyer.

The evidence caveat

The American College of Radiology does not believe there is enough evidence to recommend total-body screening for people with no symptoms, risk factors or family history suggesting serious disease. That does not make every scan irrational. It means the scan is not a proven population-health intervention.

A full-body scan can find something important. It can also find something vague, benign or not clinically useful. The scan is the start of the decision tree, not the end.

How to choose

Choose Neko if you want a fast baseline and doctor conversation without MRI-level cost. Choose Prenuvo if the core desire is MRI and you accept the price. Choose Ezra/Function only after confirming the current price and scan scope. Choose Human Longevity if you want a high-touch executive day with genomics and physician review.

The best question before booking is: who owns the follow-up if something is abnormal? If the answer is "my already-overloaded GP", count that burden as part of the price.

Who should skip

Skip if you are healthy, low-risk, prone to health anxiety and have no clinician ready to interpret ambiguous findings. Also skip if the marketing makes you think a normal scan means you are safe. False negatives are part of screening too.

FAQ

Are full-body MRI scans proven to extend life?

No. They may find important disease in some people, but there is no documented evidence that total-body screening is cost-efficient or effective in prolonging life for asymptomatic average-risk people.

Is Neko Health the same as Prenuvo?

No. Neko is a sensor, skin, cardiovascular and blood-marker visit with a doctor consult. Prenuvo is a whole-body MRI provider.
