Methods: Ten mCi of 99mTcO4- solution was instilled into the upper part of rectum. Scintigrams were taken sequentially at 15-second interval by time-lapse camera and radioactivities were recorded with VTR. Results: In 4 patients without hepatic diseases and 10 cases with chronic hepatitis, the scintigrams visuahzed the portal system, liver and heart succesively. In 24 of 26 cases with hepatic cirrhosis however, the scintigrams clearly visualized the heart earlier than the liver. In chronic hepatitis, appearance-time of radioactivities at the liver sequentially followed VTR was earlier than that at the heart. But, in 24 of 26 cases with hepatic cirrhosis, appearance-time at the liver was later than that at the heart. Portal shunt index was 0% to 10% in normal subjects, 8% to 24% in chronic hepatitis. The index was more than 25% in all cases with hepatic cirrhosis. In conclusion, our per-rectal portal scintigraphy is a non-invasive, useful method for analysing the portal circulation.
