| Abstract | 「要旨」安静時201Tl心筋シンチグラフィ(安静時シンチ)が左室造影(LVG)より算出した左室駆出率(LVEF)の推定に供用可能かを検討した. 対象は安静時シンチとLVGを施行した54例で, 心筋梗塞例(I群: 28例), 非心筋梗塞例(II群: 26例)に分類した. 安静時シンチから得たパラメータはExtent Score(ES), Severity Score(SS), Percent Uptake(PU), Area Index(AI)である. AIはSPECTの短軸断層像における心筋像の内・外縁のトレースから得た面積の比より求めた. I群では, ES, SS, AIとLVEFは相関を認め, ES≦0.30, SS≦26.2, AI≦19.8の場合, LVEF≧60%の可能性が高かった. II群では, ES, SS, AIとLVEFは相関しなかった. PU<70%の領域が左前下行枝または回旋枝領域に存在する場合, LVEF<60%のことが多かった. 以上より, 一部の症例においては, 安静時シンチの所見からLVEFが推定可能と考えられた. |

| Abstract | To determine if resting 201Tl myocardial scintigraphy (rest-Tl) provides the information on left ventricular function, we compared preliminarily the parameters derived from rest-Tl with left ventricular ejection fraction (LVEF) derived from left ventriculography; while the parameters included Extent Score (ES), Severity Score (SS), Percent Uptake (PU), Area Index (AI). AI was derived from the averaging of {(A/B)×100} in three or four central slices of short axis view on single photon emission computed tomography (A; area surrounded by inner edge of 201Tl myocardial image, B; area surrounded by outer edge of 201Tl myocardial image). The patients were comprised of 38 males and 16 females with a mean age of 53 years old (range 15-70) and classified into two groups; patients with myocardial infarction (n=28, Group I), and patients with miscellaneous disease but without myocardial infarction (n=26, Group II). In Group I, ES, SS and AI correlated with LVEF. If ES was less than 0.30, SS was less than 26.2, or AI was less than 19.8, LVEF was suggested more than 60% with an accuracy of 92%, 85% and 85%, respectively. In Group II, these did not correlate with LVEF. If there were area with PU < 70% in the region perfused by left anterior descending artery or left circumflex artery, LVEF was less than 60% with an accuracy of 78%. In conclusion, rest-Tl images provide some informations on left ventricular function in some patients. |
