False-Positive Radionuclide Hepatobiliary Imaging Following Cystic Duct Stone RemovalZAGORIA, RONALD J., M.D.; COWAN, ROBERT J., M.D.; DYER, RAYMOND B., M.D.; HERRERA, MARCOS, M.D.Clinical Nuclear Medicine: March 1989 - Volume 14 - Issue 3 - p 153–155 article: PDF Only Buy Abstract Author InformationAuthors The authors report a case in which a radionuclide hepatobiliary image was falsely indicative of cystic duct obstruction in a patient with an Indwelling cholecystostomy tube and an externalized gallbladder-duodenal stent. Cystic duct patency was demonstrated radiographlcally shortiy before and after the radlonuclide study. The authors recommend that cystic duct obstruction indicated by a radionuclide hepaloblliary image be confirmed by another means if a cholecystostomy tube is present, or If the patient recently has undergone percutaneous gallbladder or cystic duct manipulations.
