| Abstract | 「要旨」 運動負荷時, 負荷3時間後, Tl 2回分注法による心筋シンチグラフィを施行し, 梗塞部心筋のviabilityの評価法としての有用性について検討した. 陳旧性心筋梗塞症37例中, 運動負荷3時間後像で, 不完全もしくは部分的再分布を認めたのは15例 (41%) , 認めなかったのは22例 (59%) であった. Reinjectionにより, 再分布を認めた15例中7例 (19%) , 再分布を認めなかった22例中3例 (8%) , 合計10例 (27%) の梗塞部にTlの取り込み増加を認めた. また, 全37例中13例で行ったReinjection像と安静時像の比較では, 梗塞部のTl取り込みの程度はほぼ同等であった. 本法は, 運動負荷後再分布像による梗塞部心筋のviabilityの過小評価を補う有用な方法であると考えられた. 「I. はじめに」 梗塞部心筋のviabilityを評価する1つの方法として, 運動負荷Tl心筋シンチグラムが広く用いられており, その有用性は周知のごとくである. |

| Abstract | [Summary] To assess viability of the infarcted myocardium, we performed stress Tl-201 myocardial scintigraphy using reinjection method in 37 patients with old myocardial infarction, and in 13 patients of them, Tl myocardial imagings were performed in resting state on the other day within 4 weeks after this examination. In this method, 111 MBq (3mCi) of thallium was injected at the peak of exercise and initial and delayed images were acquired, then additionally 37 MBq (1mCi) of thallium was injected after delayed scanning (reinjection) and we obtained post-reinjection images. Delayed images showed redistribution in 15 patients (41%) , and no redistribution in 22 patients (59%) . In post-reinjection images, 7 (19%) of 15 patients with redistribution and 3 (8%) of 22 patients without redistribution showed improvement of thallium uptake, in total 10 patients (27%) had additional thallium uptake in infarcted regions. And the degree of thallium uptake in post-reinjection images were almost equal to that in resting images. In conclusion, myocardial imaging using thallium reinjection method may be useful for the assessment of viability of the infarcted myocardium. |
