Abstract
Abstract In an endeavour to improve the diagnostic specificity of the hepatoscan, blood clearance rates using a subcritical dose of colloidal 198Au have been used to help the scan interpretation in various liver diseases. The liver diseases, divided into those with (1) diffuse abnormalities and (2) cold areas, according to the scan appearances, are correlated with the clearance rate, which has been classified as either delayed, unaltered or accelerated following all-contrast statistical judgment. The blood clearance rates differed significantly in diseases of the same scan appearance providing a quantitative aid to scan interpretation. Thus, the clearance rate was delayed in cirrhosis, chronic hepatitis (1) and primary hepatoma (2), whereas it remained unaltered in cirrhosis complicated by secondary hypersplenism, fatty liver, acute hepatitis, biliary cirrhosis (1) and pyogenic abscess (2). In contradistinction, the clearance rate was accelerated in typhoid liver especially in the early phase (1), amoebic...
