Abstract
This exhibit was prepared to show how the hepatic photoscan using rose bengal I 131 may supply precise and unique data in the differential diagnosis of jaundice. The hepatic photoscan localizes discrete lesions causing jaundice, such as abscess, hepatoma, and metastases.1The technique pictorially indicates the size, number, and location of lesions by anterior and lateral views. The pattern of the scan indicates the parenchymal cells as the site of the abnormality in acute hepatitis and may suggest it in cirrhosis. Good uptake of the tagged material by the liver of jaundiced patients indicates good parenchymal function. If the standard cholecystogram and the cholangiogram after intravenous administration of radiopaque substance fail to demonstrate the gallbladder and the common duct in patients with jaundice due to extrahepatic obstruction, the photoscan may delineate the dilated gallbladder or duct system. Demonstration of the isotope in the gallbladder without its concomitant or later
