RI-angiography with 99mTcO4- was carried out using a scintillation camera with a digital minicomputer for the purpose of imaging of bronchial blood flow in various lung diseases, and as application of dual radioisotope techniques, other imagings such as tumor imaging with 197HgCl2 or 67Ga-citrate and/or perfusion imaging with 99mTc-MAA, were performed simultaneously in patients remaining the same position, too. The image as a iso-count map extracted out of the image of 197HgCl2, 67Ga-citrate or 99mTc-MAA, was superimposed to the brightness image of RI-anigogram (aortic phase). By these procedures, the image of bronchial blood flow were obtained in some patients with lung cancer, pulmonary tuberculosis, lung abscess, and chronic bronchitis. The dual radioisotope techniques using RI-angiography and the other imaging were useful to make isotope diagnosis of lung diseases more reliable, and the image superimposition methods using RI-angiogram and the image of tumor or perfusion, were useful to improve anatomic orientation of the former.
使用带有数字小型计算机的闪烁照相机进行99mTcO4-放射性核素血管造影，以对各种肺部疾病的支气管血流进行成像。作为双放射性核素技术的应用，在患者保持相同体位的情况下，还同时进行了其他成像，如用197HgCl2或枸橼酸镓67Ga进行肿瘤成像和/或用99mTc-MAA进行灌注成像。从197HgCl2、枸橼酸镓67Ga或99mTc-MAA的图像中提取的等计数图图像，被叠加到放射性核素血管造影（主动脉期）的亮度图像上。通过这些步骤，在一些肺癌、肺结核、肺脓肿和慢性支气管炎患者中获得了支气管血流图像。使用放射性核素血管造影和其他成像的双放射性核素技术有助于使肺部疾病的同位素诊断更可靠，而使用放射性核素血管造影与肿瘤或灌注图像的图像叠加方法有助于改善前者的解剖定位。
