Diffusion-weighted imaging technology detects pancreatic tumors

Adding diffusion-weighted MRI (DWI) to conventional imaging improves differentiation between recurrent tumor and fibrosis after cancer resection surgery, a new study said.

According to the American Journal of Genetics, these findings point to a potential role for diffusion-weighted imaging in post-tumour surveillance protocols.

The study was conducted at the Samsung Medical Center in Seoul, South Korea, and showed that the DWI technology improves the sensitivity of magnetic resonance imaging by twice as much, and that it facilitates early detection of recurring cases of cancerous tumor growth, and thus faster treatment decisions.
