Visualization of the gallbladder after nonfractionated and fractionated administration of iopanoic acid was investigated in a blind experiment. The authors studied 168 patients; 73 were given 3 g iopanoic acid over a period of 6 hours (0.5 g/hour), and 95 received the same amount of contrast medium in a single dose. No differences in visualization were found for the two modes in both normal and pathological cases.
