Fig. 2From: Value of high frame rate contrast enhanced ultrasound in gallbladder wall thickening in non-acute settingUS images of xanthogranulomatous cholecystitis. (a) Thickening of gallbladder wall on B-mode US image (GB-RADS 4). (b) Vascularity in GWT on color Doppler flow imaging. (c-f) Enhancement direction of GWT is from inner to outer, with regular vascular morphology. (g) Wash-out time is 70 s. (h) Schematic diagram of the enhancement pattern of GWT mimicking malignancy on H-CEUS images.
