 note = {Recent advances of various body imaging apparatus and development of sensitive assay system for AFP enable us to make early detection of small hepatocellular carcinoma. (sHCC). To establish more logical screening method of sHCC, diagnostic accuracy and reliability of each imaging system in 29 sHCCs (Hepatocellular carcinoma under 3 cm in diameter) was evaluated in comparison with clinico-pathological features. Sensitivities of each imaging apparatus in detection of sHCC were 57% by radionucleotide scanning (RI), 76% by ultrasonography (US), 83% by computed tomography (CT), and 85% by celiac angiography (CA), respectively. Image finding characteristic to sHCC was solid and low echoic lesion by US, serial disapperance of visualized lesion by dynamic CT, and faint diffuse staining of the lesion by CA. Small lesions around 2cm in diameter could be detected by collaborative assessment by US, CT and CA. There existed no specific risk factor to develop SHCC. Serum AFP level of 17% of sHCC remained within normal range. These data suggests the importance of periodical screening, in high risk group for liver cancer, by integrated body imaging systern in early diagnosis of sHCC. Author emphasizes the benefit of US for sHCC screening because of noninvasive and easy available method.},
