Fig. 1From: Increased enhancement of the liver adjacent to the gallbladder seen with contrast ultrasound: comparison between acute cholecystitis and non-cholecystitisTime-intensity curves. a, Time-intensity curve of the non-cholecystitis group. The intensity ratio was defined as follows: the peak intensity of segment 5 (arrow A) divided by the simultaneous value of segment 8 (arrow B). Red line, segment 5; blue line, segment 8. b, Time-intensity curve of the acute cholecystitis group. The intensity ratio was defined as follows: the peak intensity of segment 5 (arrow A) divided by the simultaneous value of segment 8 (arrow B). Red line, segment 5; blue line, segment 8Back to article page
