DWI bei akuter Cholezystitis

Diffusion-weighted

MRI: findings and role in acute cholecystitis. High (800) b-value diffusion-weighted images (d,e) showed visually hyperintense signal in the gallbladder wall (arrows) indicating acute inflammation, and pancreatic gland (*) gradually progressive hypersignal consistent with oedematous acute pancreatitis from tail to head.

Diffusion-weighted

MRI: findings and role in acute cholecystitis. Apparent diffusion coefficient map showed hypointensity indicating restricted diffusion in gallbladder wall (arrow, 1.45-1.6x10-3 mm2/s) and pancreas (*, progressively increasing from 0.8 at head to 1.1x10-3 mm2/s in tail).
