Computed tomography in hepatobiliary diseases

Computed Tomography (CT) was introduced to detect lesions in 48 cases with various hepatobiliary disease. In 8 out of 11 cases with liver cell cancer, diagnosis were made by CT. A case was detected in early stage, the low density area was so small that it can be resected segmentally. In 7 out of 9 cases with metastatic liver cancer, multiple low densities were detected by C.T. Gallbladder cancers, which is known as diagnostic difficulty, were detected in five cases as low density in gallbladder area. CT has superiority to liver scintiscan, 1) CT can determine the tumor more exactly except for the diffuse type. 2) CT can be performed repeatedly without any risk and use of isotopic substances. 3) CT observes the transverse configuration of the organ, which could not be done in any conventional method.
