| Abstract | 「要旨」シンチカメラ-ミニコンピュータシステムを用いて原発性肺癌26例などの呼吸器疾患を対象に99mTcO4-のRI-アンジオグラフィーを実施し, 気管支動脈血流の描画につき検討した. 原発性肺癌では高率に, また, 肺結核, 肺化膿症, 気管支拡張症などでも描画された. 大動脈相での時相の異なる2画像間のサブトラクション法により気管支動脈血流の描出が容易となった. 本法に腫瘍シンチグラフィーや肺血流シンチグラフィーを併用し, これらの画像をRI-アンジオグラムに重ね合せることにより, 情報量が多くなり, その意味づけも容易となった. RI-アンジオグラムにおける気管支動脈血流の描出度および気管支動脈造影像での血管増生度と197Hg Cl2の集積度との間にはおのおの同様な相関が認められ, 前二者の間にも密接な関連が推定された. |

| Abstract | [Summary] Nuclear angiocardiography with 99mTcO4- was performed for the purpose of the delineation of the systemic perfusion in various lung diseases, using a scintillation camera with a digital mini-computer system. The images of the bronchial blood flow were obtained in cases with primary lung cancer, pulmonary tuberculosis, lung abscss, bronchiectasis and chronic bronchitis. The fair images of the bronchial blood flow were taken in cases of peripheral type, adenocarcinoma and primary foci of atelectatic type in primary lung cancer. The grade of delineation of the bronchial blood flow and vascularity of bronchial artery in foci of primary lung cancer were correlative to the grade of accumulation of 197HgCl2, respectively. The joint use of nuclear angiocardiography and other imagings such as tumor or perfusion one was useful for evaluation of the pulmonary and systemic circulation, and that made isotope diagnosis of primary lung cancer more reliable too. The image as a isocount map extracted out of the image of 197HgCl2 or 99mTc-MAA, was super-imposed to the brightness image of the nuclear angiocardiogram (aortic phase). This image superimposition methods were valuable to improve anatomic orientation of the nuclear angiocardiogram. The delineation of the bronchial blood flow on the subtraction image, which obtained from the two time-different images in aortic phase of the nuclear angiocardiogram, was better than that of the original images. |
