| Abstract | 「要旨」 肥大型心筋症の運動負荷201Tl心筋SPECTにおいて, 時に認められる逆再分布現象について検討した. 運動負荷201Tl心筋SPECTにおいて, 視覚的に逆再分布現象の認められた冠動脈狭窄を有さない, 肥大型心筋症10例を対象とした. 運動負荷201Tl心筋SPECTの初期像および遅延像より, 逆再分布現象を視覚的に判定した. 断層心エコー図および心MRIより判定した肥大および非肥大部位と逆再分布現象の発現部位とを対比し, さらに, Washout rateのBull's eye表示を参考としてその発現機序を検討した. 逆再分布現象は, 非肥大部位に認められ, Washout rateは逆再分布現象を示した部位で正常, 肥大部位で低下した. 肥大型心筋症の運動負荷201Tl心筋SPECTにおける逆再分布所見は肥大部位を念頭におき, Washout rateを参考に解釈することが必要と考えられる. |

| Abstract | [Summary] Reverse redistribution is revealed on exercise 201Tl myocardial SPECT in some cases with hypertrophic cardiomyopathy. Ten patients with hypertrophic cardiomyopathy without coronary artery disease who showed reverse redistribution visually were studied. Reverse redistribution was evaluated by the early and delayed images of exercise 201Tl myocardial SPECT. Relation between reverse redistribution and distribution of left ventricular hypertrophy estimated by echocardiography and magnetic resonance imaging was investigated, and the mechanism of reverse redistribution was analyzed by referring to Bull's eye display of washout rate. Reverse redistribution was displayed in non-hypertrophic region and washout rate was normal in that region and low in hypertrophic region. In conclusion, in order to interpret reverse redistribution it is necessary to recognize hypertrophic region and to refer to washout rate. |
