Diffusion-weighted imaging technique suppressing background body signal for improved lesion visualisation
Expansion
Diffusion-Weighted Imaging with Background Body Signal Suppression
Purpose
Enhanced sensitivity for small lesions, metastases; used in whole-body staging
Clinical Context
Diffusion-weighted imaging with background body signal suppression: inverted background signal highlights restricted diffusion lesions. Whole-body staging for cancer; detects bone, liver, lung metastases.

Key Points
- Diffusion-weighted imaging with background body signal suppression very sensitive for bone metastases and small lesions; high signal intensity indicates restricted diffusion
