The Claim
Whole-body MRI has a negative predictive value of 97.4% in adults with Li-Fraumeni syndrome, indicating that a normal scan result strongly suggests the absence of cancer at the time of scanning, but does not guarantee that cancer will not develop prior to the next scheduled scan.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
If you have Li-Fraumeni syndrome and get a whole-body MRI that shows no cancer, there’s a 97.4% chance you really don’t have any right now — but it doesn’t mean you won’t get cancer before your next scan.
See the scientific wording
Whole-body MRI has a high negative predictive value (97.4%) in adults with Li-Fraumeni syndrome, meaning a normal scan strongly suggests the absence of cancer at that time, but this does not guarantee cancer will not develop before the next scan.
What the research says
1 studyStudy: Evaluation of whole-body MRI for cancer early detection in Li-Fraumeni syndrome
This study found that when a whole-body MRI scan comes back normal in people with Li-Fraumeni syndrome, there’s a 97.4% chance they really don’t have cancer right now — but it doesn’t mean they won’t get cancer later, before their next scan.
