Liver Color Scan에 대(對)한 고찰(考察)

Observation of Liver Color Scan

In the past few years, scintigraphy has become increasingly important in clinical practice, and the use of a color-printing technique has permited a more accurate interpretation of the scan image. Our liver color scintigrams consist of 51 hepatomas, 35 liver cirrhosis, 22 liver abscessis, 10 hepatitis and other 13 cases of the liver diseases which were clinically arid pathologically diagnosed at Sevarance Hospital, Yonsei Univ., since Feb. 1969 through Sept. 1969. These scintigrams have been analized in terms of various pathologic morphology, such as size, shape, margin of the liver, distribution of radioactivity, and shape of the space occupying lesions. The results are as follows: 1. Enlargement of the liver was the most common finding in the diseased livers. The Rt. lobe enlargement was particularly prominent in the liver abscess. 2. Irregular distribution of radioactivity in the liver (so called mottling) was present in 78% of hepatoma, while it was seen only in 31% of liver abscesses. 3. Liver cirrhosis tends to show perihilar accumulation of the isotope (57%). 4. The deformity of the lower most angle of the Rt. lobe, and the Lt. lateral margin of the Lt. lobe was also impressive throughout the cases ($74{\sim}95%$ of all diseased livers). 5. The frequency of visualization of the spleen was influenced by the size of space occupying lesions and the amount of functioning liver. 6. Differentiation between the liver abscess and hepatoma seems to be possible on scintigram, when shape and margin of defect and patterns of distribution of radioactivity in the remaining liver are clearly demonstrated.
