| Abstract | 「要旨」MAAによる肺血流シンチグラフィーにおいて, 1側肺全体のactivityの低下した状態をunilateral hypoperfusion lung(UHL)と呼び, 59例につき臨床的意義を検討した. 肺癌, 気管支異物, 肺および肺動脈形成異常, Swyer-James症候群などでこの状態が見られた. X線写真から容易にUHLを想像し得ることもあるが, X線写真ではあまり所見のない肺野のlucent〜hyperlucentの例でもこの状態を示すことがあった. 肺動脈造影像とUHLとはよく一致した. 気管支造影や133Xeガスによる換気シンチグラフィーも行い, 特に133Xeを加えることにより, 換気を含めた病態がよく把握された. 一方, X線写真上ある一つの所見を示す場合, 原因となる疾患や状態をすべて取りあげて整理し, リストを作って検討することは, Gamutといわれ, 鑑別診断や医師の教育に役立つとされている. 核医学でもシンチグラムに適用されており, この点からも検討した. |

| Abstract | [Summary]The term unilateral hypoperfusion lung (UHL) is here used to indicate decreased unilateral activity of the lung as determined in the lung perfusion scintigram. The same condition has been referred to by other authors as absent perfusion of one lung, unilateral absence of pulmonary artery perfusion, total lack of pulmomary artery perfusion of one lung, bloodless lung, decreased unilateral perfusion of the lung, unilateral pulmonary hypoperfusion, nonperfusion of one lung and absence of radioactivity over one lung. We studied 59 cases of UHL, including pulmonary carcinoma, bronchial foreign body, hypo- or a-plasia of the lung or pulmonary artery, unilateral pleural effusion, post-operative and Swyer-James syndrome. Using scintigram, UHL was found even where slight or no abnormalities showed up on plain x-ray film, and the finding of UHL was especially useful to evaluate blood flow in the lucent or hyperlucent lung. Scintigraphic and pulmonary arteriogram findings corresponded. Bronchography or ventilation scintigraphy with 133Xe gas was also performed in some cases, and this additional ventilation study was effective in advanced diagnosis of chest diseases. On the other hand, "Gamut" which indicates a complete list of causes of a particular x-ray finding is available in the differential diagnosis or resident training. In a field of nuclear medicine, a gamut approach had also begun to be applied recently, so UHL was evaluated at this point of view. |
