Surprising Findings
The 99.8% negative predictive value for no interval cancer
Most people assume MRI scans have high false negatives, but this claims near-perfect reliability in ruling out cancer within a year—far higher than most assume for any screening tool.
Practical Takeaways
If you’re at high risk for multiple cancers or have a strong family history, ask your doctor if WB-MRI might be appropriate as a supplemental tool—not a replacement—for standard screenings.

Using a full-body MRI scan might help find cancers in body parts where doctors don’t normally screen people, like without a regular test.
A full-body MRI scan can find cancer in about 1 to 2 out of every 100 people who feel fine and have no symptoms — and that’s more than what mammograms or lung CT scans find on their own, so it might be a good way to catch multiple types of cancer early.
When doctors use full-body MRI scans on people who feel fine, about two out of three cancers they find are in body parts that don’t usually get checked during routine screenings—so this scan might catch cancers other tests miss.
If a whole-body MRI scan comes back negative, there’s a 99.8% chance you don’t have any new cancer developing in the short term—especially if you didn’t need a biopsy after the scan.
Instead of choosing between whole-body MRI and regular cancer tests like mammograms, doctors should use both together — because MRI can find cancers that other tests don’t check for.
