Magnetic Resonance Whole Body Diffusion-Weighted Imaging

**Semantic type:** Diagnostic Procedure

**Definition:** A non-ionizing radiation imaging modality for quantitative assessment of disease burden and therapy response. WB-DWI uses the apparent diffusion coefficient (ADC) measurement to detect and quantify disease. ADC is influenced by tissue microarchitecture and may be altered in a disease state.
