[Differential diagnostic procedures in localized liver diseases]

Liver scintigraphy by means of 99mTc-sulphur colloid (n = 430) and 67Gallium-citrate (n = 180) were carried out on selected patients, on a follow-up study. This study was undertaken to prove the possibility of early diagnosis of primary hepatic carcinomas. Only autoptically verified cases (n = 119) were used for the evaluation of the accuracy of liver scans. 99mTc-s.c. -scans predicted the presence or absence of focal liver diseases in 78% of the cases. Scan data were falsely positive in 10% and falsely negative in 28%.
