Authors analyzed ultrasonographic findings and compared the detectability of ultrasonography and RI scintigraphy of the 140 hepatic focal lesion, provened histologically or clinically. The results were as follows: 1. Hepato ma cases were 69 cases. 2. Metastatic Ca cases were 42 cases most frequently originated from stomach and pancreas. Small multiple lesions with hyperechoic or mixed echo pattern was predominant finding with relatively even distribution in the both lobe. 3. There was no apparent association between sonographical echogenecity and angiographic vascularity. 4. Sensitivity of the sonography for the detection of focal lesions was 90%, while RI scintigraphy was 82%. False negative lesions in the ultrasonography were frequently located in right lobe lateral and peripheral aspect. While in the RI scintigraphy, those lesions were frequently in the right lobe central aspect wity close correlation with size of the lesion.
