Time-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 8
