title: [Evaluation of hepato-biliary functional scintigraphy with 99mTc diethyle-IDA. Findings in normal livers (author's transl)].
abstract: Hepato-biliary functional scintigraphy was performed on 51 patients with normal livers after in the injection of 99mTc diethyle-IDA. The results were analysed according the morphological criteria (demonstration of the bile duct, intra-hepatic ducts, gall bladder and renal tract) and functional criteria (T max, half-time biliary excretion values, development of activity in the bile duct, in the gall bladder and in the gut). Demonstration of the bile duct and gall bladder was successful in all cases if the examination was carried out after an appropriate interval following food. 84.3% of patients showed a gall bladder excretary pattern of the tracer and 15.7% a gall bladder storage pattern. Correspondingly, bile appeared in the duodenum at 16.5 +/- 6.5 minutes (excretion) or 79.3 +/- 49.5 minutes (storage). The left hepatic duct was shown in 58.8%, the right hepatic duct in only 58.8%. Sixty minutes after the injection no activity could be determined in the bile ducts beyond the liver parenchyma. The gall bladder could be identified after 26.6 +/- 24.4 minutes, occasionally it was much later, up to 110 minutes. The liver function curve showed a Tmax level of 6.8 +/- 2.7 minutes and half value time of 15.8 +/- 6.7 minutes. At 5 minutes after injection the renal pelvis could be identified in 19.6%, but in no case was this still present beyond 15 minutes. Duodeno-gastric reflux was not demonstrated.
