Limitations of whole body MRI?

Whole body MRI, while effective in cancer detection, has several notable limitations. Dr. Peter Attia highlights that whole body MRI has a low specificity, meaning it can often flag non-cancerous findings as suspicious, necessitating further investigation. This is particularly problematic with glandular tissue, leading to unnecessary follow-up procedures like ultrasounds for benign conditions, such as thyroid nodules, which can be stressful and costly for patients 1.
