[Diagnosis of functional disorders of the gallbladder and bile ducts].

The technique of hepatobiliary function scintigraphy (HBFS) is described and the different stages of filling are analyzed. Continuous observation and registration of the flow of the administered test dose is undertaken so that any possible anomalies can be noted. After the administration of contraction agents (Biloptin stimulus), the function of the involuntary muscles of the gall bladder and bile ducts is examined. In this way irregularities of tone can be registered. The place of HBFS within the field of gall bladder and biliary tract diagnostics is defined.
