Sometimes, a full-body MRI scan might miss a serious problem, making doctors think everything’s fine when it’s not — and that delay could lead to really bad health results.

Multiple Myeloma and Smoldering Myeloma: Prospective Evaluation of 3 T Whole Body MRI and 18F-FDG PET/CT and Their Impact on Clinical Management

Cross-Sectional Study
Human

This study found that whole-body MRI spots more signs of serious disease than other scans, catching problems that other tests miss — which means it helps doctors diagnose serious conditions earlier, not later.

A Case of Wallenberg Syndrome Presenting With Thunderclap Headache and Delayed Diagnosis Due to Negative Findings on Two MRI Examinations

Case Report
Human
2025 Apr

Two MRI scans missed a stroke in the brain, so the patient didn't get the right treatment right away and got sicker — this shows MRIs can sometimes miss serious problems, just like the claim says.

Prospective comparison of 18F-PSMA-1007 PET/CT, whole-body MRI and CT in primary nodal staging of unfavourable intermediate- and high-risk prostate cancer

Cross-Sectional Study
Human
2021 Aug

This study found that whole-body MRI often misses cancer spread in the lymph nodes, while a different scan (PSMA-PET) catches it much more often — meaning MRI can give false reassurance and delay treatment.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Getting a full-body MRI often finds weird little things that aren’t actually a problem, which can lead to more tests and stress — but we don’t yet know if all this causes more harm than good.

Getting a full-body MRI scan if you're not at high risk for disease might find things that aren't actually problems, leading to more tests and stress — and no one has yet measured how often this happens.

When healthy people without symptoms get a full-body MRI scan, doctors often find weird little things that aren’t actually harmful—but those findings can lead to more tests and stress that might not be needed.
