title: [Hepatic clearance of 99mTc-p-butyl HIDA in liver diseases. Correlations with routine hematochemical parameters of liver function].
abstract: The aim of the present investigation was to study the clearance of 99mTc-p-butyl IDA in some acute and chronic liver diseases, it being considered that the typical parameters obtained with this method are as indicative as any of the others put forward for the study of liver function using radioisotopes. 46 subjects were examined: 6 with acute hepatitis, 10 with chronic hepatitis, 18 with liver cirrhosis and 12 with dyspepsia but otherwise normal haematochemical tests. Two basic 99mTc-p-butyl IDA clearance parameters, Tu (semi-take up time) and Te (semi-excretion time), were determined plotting the data obtained using a Gamma-Camera on semi-logarithmic paper. Mean Tu values were as follows: 5'06'' +/- 1'24'' in dyspeptics, 12'30'' +/- 6'31'' in subjects with acute hepatitis, 6'30'' +/- 1'45'' in subjects with chronic hepatitis and 13'30'' +/- 4'30'' in subjects with cirrhosis. The values were: 34'30'' +/- 4'30'' in dyspeptics, 49'54'' +/- 2'36'' in subjects with acute hepatitis, 42'24'' +/- 12'24'' in subjects with chronic hepatitis and 65'30'' +/- 39'36'' in subjects with cirrhosis. The Tu parameter was found to be delayed more significantly in cirrhotic patients and less in subjects with acute or chronic hepatitis, compared to dyspeptics with normal haematochemical parameters. Te was significantly delayed in subjects with cirrhosis and acute hepatitis, while there was no difference for subjects with chronic hepatitis. Of the routine haematochemical tests, the albumin/gamma-globulin ratio and unconjugated bilirubin were found to correlate significantly with the Tu parameter, whereas conjugated bilirubin was found to bear a significant correlation to the Te parameter.
