Technetium-99m HIDA hepatic lobar distribution and retention ratios in detection of intrahepatic lithiasis.

Technetium-99m HIDA hepatic lobar distribution and retention ratios were developed to evaluate patients with intrahepatic lithiasis. The data of 57 cases were analyzed. Results reveal a highly significant difference in these ratios between the patients and normal individuals. They are simple, objective, and easily obtainable. Thus, the determination of these ratios may replace [99mTc]HIDA sequential scintiphotography, which is qualitative and time consuming, for screening intrahepatic lithiasis.
