| Abstract | 「要旨」201Tl心筋シンチグラフィーにおける肺集積は, 本剤が肺血管通過時に肺の組織拡散スペースへの滲み出し現象と考えられ, 肺の間質性浮腫の評価の可能性が示唆される. 今回328例の安静時心筋シンチグラムの肺集積度を検討した. 正常人ではわずか1例 (5%) , 心筋梗塞117例 (78%) , 狭心症32例 (37%) , 高血圧性心疾患6例 (27%) , 肥大型心筋症7例 (30%) , うつ血型心筋症6例全例, 弁膜疾患11例全例, 先天性心疾患7例 (71%) に肺集積の増加を認めた. 特にLVEFの低下した虚血性心疾患やうつ血型心筋症, 弁膜疾患など肺うっ血を伴いやすい疾患群に高率にみられた. 胸部レ線の肺うっ血所見と比較すると, 肺うっ血の程度の増加するほど肺集積度も増す傾向があり, 本所見が肺の間質性浮腫の程度を反映するものと考えられた. 201Tl心筋シンチグラフィーは, 虚血部位の診断だけでなく, 同じ写真から同時に肺うっ血の程度の評価も可能であり, さらに有用な検査法となりうると考えられた. |

| Abstract | [Summary] We have noted increased lung uptake of thallium-201 on resting myocardial images in patients with congestive heart failure. To evaluate this phenomenon, lung uptake of thallium on resting myocardial imaging was examined in 328 patients with various cardiovascular diseases. Increased lung uptake was observed in 117 cases (78%) with myocardial infarction, 32 (37%) with angina pectoris, 6 (27%) with hypertensive heart disease, 7 (30%) with hypertrophic cardiomyopathy, 6 (100%) with congestive cardiomyopathy, 11 (100%) with valvular heart disease, and 7 (71%) with congenital heart disease, however, only one (50%) of normal subjects revealed increased uptake. Left ventricular ejection fraction was evaluated in 32 cases with ischemic heart disease on the same day and it was significantly decreased as the lung uptake of thallium increased. Increased thallium activity in the lung seemed to be another noninvasive marker of lift heart failure in ischemic heart disease. Lung uptake of thallium was compared with pulmonary congestive signs on chest X-ray in 29 cases. The uptake was well correlated with the degree of pulmonary edema, and thallium myocardial image revealed remarkably increased lung uptake in all the patients accompanied with pulmonary interstitial edema on chest X-ray. Therefore, this phenomenon will demonstrate pulmonary edema, since thallium may be extracted to the increased interstitial distribution space of the lung as well as the myocardium in a patient with pulmonary edema. We conclude that thallium myocardial scintigraphy is useful not only in identification and localization of myocardial ischemia or infarction, but also in evaluation of pulmonary edema at the same time. |
