Abstract
The clinical, echographic, radionuclide and CT [computed tomographic] studies of 19 patients with tissue-proved hepatoma were reviewed retrospectively. All patients had ultrasound examination; 18 also had 99mTc-sulfur colloid studies and 11 had Ga scans. Ultrasonically, the lesions were classified as discrete, sonodense (6 cases), discrete sonolucent (5 cases), disorganized hepatic parenchyma (6 cases) and normal parenchyma (2 cases). All sulfur colloid studies showed areas of decreased uptake, while all Ga scans showed relative increased uptake in the area of decreased sulfur colloid activity. Radionuclide imaging is more accurate than ultrasound in the diagnosis of hepatoma.
