[Studies of hepatobiliary function with a scintillation camera and electronic data processing)].

Abstract

The authors performed the sequential scintigraphy after intravenous application of 131I-BSP using the scintillation camera. During the first 60 minutes the pictures of the liver and of the mesogastrium were recorded in one-minute intervals on the digital magnetic tape. The following scintigrams were then recorded after 3 and 24 hours after the injection. Choosing the region of interest the authors noted the histograms above the liver and above the mesogastrium, evaluated then the proportion of impulse rate above the liver and mesogastrium in measured intervals and obtained using the digital computer the velocity coefficient of the radioactivity accumulation in the liver as liver chromoexcretive function parameter. The results were compared with the standard test of the 45-minutes retention of the BSP, with the analysis of the curve measured above the temporal region, with the clinical status as well as with the results of other auxiliary examination methods. According to the first experiences gained when examining 91 individuals the described method proves to be very useful.
