| Abstract | 「要旨」肝シンチグラフィーを施行する際に同時に行うTc-99mコロイド肝RIアンギオグラフィーの簡便法について, 191例の肝悪性腫瘍を対象に, その臨床的意義を検討した. 肝シンチグラムの欠損部位に一致して, RIアンギオグラフィーの肝動脈相において放射活性の見られるhypervascular patternは, 肝細胞癌39例のうち74%に観察された. しかし, 転移性肝癌では126例のうちわずかに1.6%に見られたのみであった. 肝シンチ欠損像の平均径が5.5cm以上の肝細胞癌の場合には, 84%の確率でhypervascular patternを呈し, その最小平均径は3.0 cmであった. また, 肝右葉後区域の肝細胞癌は, 深部にあるために, hypovascular patternを呈する傾向がある. 以上の結果をもとに, 本法を肝細胞癌のスクリーニング検査として用いた場合の診断率を86.4%と推測した. |

| Abstract | Tc-99m phytate liver angiography was accomplished in 191 cases with focal liver disease at the same time of performing conventional liver scintigraphy from July 1978 to Feb. 1981. This simple method was considered to be useful to appreciate tumor vascularity in the liver, which was shown as dynamic radioactivity in the defect of the liver Scintigram. Hypervascular pattern was defined as a highradioactivity on the arterial phase of RI angiography, which corresponded to the filling defect on the static liver scintigram. This pattern was influenced by three factors, i. e. pathological vascularization of the tumor, size of the filling defect and position of the defect in the liver. In 29 cases(74%)of 39 hepatocellular carcinoma, hypervascular pattern was observed. When mean diameter of defect was more than 5.5 cm on liver scintigram, it was supposed that hypervascular pattern should be observed in probability of 84%. The smallest mean diameter of defect in which this pattern was seen was 3.0 cm. When a filling defect was situated at the posterior region of the right lobe of the liver, it was sometimes difficult to appreciate the vascular pattern. Tc-99m phytate liver angiography was considered to be a useful method for screening hepatocellular carcinoma. |
