[2025-09-25T11:34:59.995878] [PI reasoning] **Considering diffusion-weighted MRI**

I’m thinking about whether diffusion-weighted MRI is useful in detecting cancer during nonenhanced MR imaging. It seems likely yes. I recall a PubMed article from around 2006 that examined this topic, focusing on uterine endometrial cancer. The study found that adding diffusion-weighted imaging to T2-weighted imaging improved cancer detection. So, my answer is yes, but I need to support this with proper evidence. A quick search might help solidify that.
