Diffusion-weighted imaging of biliopancreatic disorders: Correlation with conventional magnetic resonance imaging

Figure 9 Gallbladder carcinoma (focal wall-thickening type) in a 77-year-old woman. A: Axial contrast-enhanced, fat-saturated, T1-weighted image shows focal wall thickening (arrowheads) in the gallbladder with a metastatic lymph node in the portocaval space (arrow); B: Fusion image of T2-weighted image and DWI at b = 800 s/mm² shows focal, asymmetric high signal intensity in the fundal portion of the gallbladder (arrowheads) with a hyperintense metastatic lymph node in the portocaval space (arrow). DWI: Diffusion-weighted magnetic resonance imaging.
