Abstract「要旨」単検出器型ガンマカメラを用いた心電図同期99mTc-MIBI SPECTを施行し, 同法の壁運動評価の妥当性, 有用性について検討した. 陳旧性心筋梗塞16例, 正常17例を対象とした. 一心拍を8等分する動画像表示による定性的壁運動評価と心エコー検査の評価とを比較した. 定量的評価法として壁のカウント増加(%count increase, およびrelative count increase)を算出し同心円表示した. 正常例の検討では前壁, 下壁, 側壁のカウント増加はほぼ等しく, 心尖部は3区域より有意に高く, 中隔は低かった. 動画像による壁運動評価は心エコー検査の評価とよく一致した(一致率97%, 完全一致率60%). 心エコー検査による壁肥厚率と壁のカウント増加は弱い正の相関を認め, 心エコー検査上壁運動が低下するにつれ壁のカウント増加も低下する傾向を認めた. 本法による壁運動評価はほぼ妥当なものであり, 心筋血流と心機能の同時解析が可能と思われた.

Abstract[Summary] ECG-gated 99mTc-MIBI SPECT was performed in 33 patients, including 17 normal subjects and 16 patients with old myocardial infarction. To compare the findings by echocardiography (UCG), regional wall motion was qualitatively assessed by cine-mode display and quantitatively measured as an increase in regional count from end-diastole to end-systole. The percent count increase and relative count increase was measured to display on the Bull's eye polar map. In the study of normal subjects, the count increase was greater in apical regions and smaller in septal regions. Regional wall motion by this method correlated well with UCG findings (agreement: 97%, complete agreement: 60%). A mild but significant correlation was observed between the count increase by this method and the percent wall thickening by UCG. We conclude that regional wall motion can be accurately evaluated with ECG-gated 99mTc-MIBI SPECT, which thus permits simultaneous assessment of regional wall motion and myocardial perfusion.
