Dynamic computed tomography in various hepatic diseases. Particular reference to detection and differential diagnosis of hepatocellular carcinoma

Journal Article:

Abstract

Studied were 140 cases of hepatoma, 40 of metastatic liver tumor, 18 of hemangioma, 9 of liver cirrhosis, 10 of chronic hepatitis and 10 patients with no liver disease. The dynamic CT was obtained before, 10, 30 and 50 seconds after an intravenous bolus injection of 50 ml of 65 % meglumine diatrizoate. Normal liver parenchyma and portal vein were slightly enhanced on the arterial phase and moderately enhanced on the portal phase of the dynamic CT. There was no significant change in case of chronic hepatitis, but in case of liver cirrhosis, the liver parenchyma was less enhanced than the normal liver on the portal phase. Tumor enhancement on the arterial phase was classified into 6 patterns, namely, A : homogeneous, B : inhomogeneous, C : patchy, D : ring, E : peripheral and F : no enhancement, while time-density-change was classified into 4 types, namely, type I : the tumor was most enhanced on the arterial phase, type II : the tumor was most enhanced on the portal phase, type III : tumor enhancement increased with time, type IV : there were no significant changes with time. Hepatoma was characterized by patterns A, B and C tumor enhancement  More>>

Tumor enhancement on the arterial phase was classified into 6 patterns, namely, A : homogeneous, B : inhomogeneous, C : patchy, D : ring, E : peripheral and F : no enhancement, while time-density-change was classified into 4 types, namely, type I : the tumor was most enhanced on the arterial phase, type II : the tumor was most enhanced on the portal phase, type III : tumor enhancement increased with time, type IV : there were no significant changes with time. Hepatoma was characterized by patterns A, B and C tumor enhancement and type I time-density-change, while metastatic liver tumor featured patterns D and F tumor enhancement and hemangioma was characteristic in indicating pattern E tumor enhancement and type III time-density-change. The rate of accurate diagnosis was 92 %. Small hepatoma (less than 5 cm in diameter) could be detected by conventional CT only in 38 out of 50 cases (76 %), while dynamic CT revealed an additional 8 cases. Out of 21 cases of portal vein thrombosis, 14 cases (66.7 %) were detected by the conventional CT but dynamic CT improved the rate of detection to 92.0 %. Dynamic CT also revealed 6 cases of arterioportal shunt which could not be detected at all by conventional CT. Thus dynamic CT provides useful information and should be considered as one of the routine tests in CT examination of the liver. (J.P.N.).}
