Prenuvo (Whole-Body MRI)

What it is

Prenuvo offers ~1-hour whole-body MRI scans (no contrast, no radiation) marketed to consumers in major US cities and selected international markets. Cost is typically $1,000–2,500 per scan.

What it can detect

• Solid organ masses (kidney, liver, pancreas).
• Spinal disease and disk pathology.
• Aneurysms.
• Joint and soft-tissue abnormalities.
• Some brain pathology.

What it cannot detect

• Coronary artery disease (use CAC or coronary CT).
• Many lung pathologies (use low-dose CT in eligible patients).
• Microscopic disease and many early cancers.

The incidentaloma problem

Cross-sectional imaging of asymptomatic adults reveals findings of unclear significance in a substantial minority. These “incidentalomas” prompt further imaging, biopsies, and follow-up that often turn out to be benign — carrying real cost, anxiety, and procedure risk.

Trade-offs

• High informational yield in highest-risk individuals.
• Lower yield in low-risk asymptomatic individuals, where harms of follow-up may exceed benefits.
• Not covered by insurance.
• Should not replace structured guideline-recommended screening (mammography, colonoscopy, cervical screening, etc.).
