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

Figure 10 Xanthogranulomatous cholecystitis in a 55-year-old man. A: Axial T2-weighted rapid acquisition relaxation enhancement image shows focal wall thickening with a fundal mass (arrowheads). There is focal high signal intensity within the thickened wall of the gallbladder; a finding that is consistent with an intramural collection; B: DWI at b = 800 s/mm² shows focal high signal intensity in the fundal portion of the gallbladder (arrowheads). Xanthogranulomatous cholecystitis was confirmed by laparoscopic cholecystectomy. DWI: Diffusion-weighted magnetic resonance imaging.
