Whole-Body MRI Screening Costs $108,000 Per QALY as Experts Still Reject Routine Use

Summary
$108,000 per quality-adjusted life year is the report’s rough estimate for whole-body MRI screening, placing it near the usual $100,000 cost-effectiveness threshold rather than clearly favorable.
Per 1,000 asymptomatic people screened, the analysis estimates 8 benefit, gaining about 32 QALYs, but 300 trigger follow-up tests and 20 biopsies, generating $2.7 million in costs, 6,200 patient hours and about 5 QALYs of harm.
False positives, anxiety and side effects drive much of the downside: 29% of those with uncertain findings report moderate or severe distress, and repeated annual screening would likely worsen the per-scan value.
Doctors still advise against routine whole-body MRI because the estimate relies on low-quality studies, secondary endpoints and optimistic assumptions about follow-up care, overdiagnosis and patients’ ability to avoid harmful reactions.
For wealthy patients who discount money and tolerate uncertainty, the author argues screening could be mildly net positive, while saying newer whole-body ultrasound systems remain too untested to judge.
