A two year experience with 99mTC HIDA cholescintigraphy in teaching hospital practice.

One hundred and thirty-four sequential patients who underwent 99mTC HIDA cholescintigraphy have been studied. Patients were investigated for suspected acute cholecystitis, chronic cholelithiasis, enterogastric reflux or jaundice, and in the assessment of biliary tract drainage after transplantation of the liver and other operations of the biliary tract. The technique is most valuable in the diagnosis of acute cholecystitis when its accuracy rate is 96 per cent; it is also useful in the assessment of postoperative biliary drainage. It is least helpful in the investigation of jaundice and suspected chronic cholelithiasis.
