Abstract「要旨」Tl-201心筋シンチグラフィ, 心電図同期心プールシンチグラフィにsingle photon emission computed tomography(SPECT)を用い, Tl-201心筋摂取量, 心筋からのwashout, 心室壁運動, 位相の心機能マップを作製する方法を考案した. 各パラメータは極座標を用いて同一の形式で表示した. 正常対照患者(n=16)において心筋血流, washoutの正常値を検討したところ, 血流分布は下壁中隔で低いが男の方がより低く, 性差を認めた. またwashoutは男では下壁と中隔が, 女では下壁が, 前側壁より遅いパターンを示した. 断層心プール法については, 長さの変化およびカウント変化に基づくフーリエ解析法を応用して心表面の収縮と位相の分布を作製した. 両者はほぼ一致するが, その範囲には差が認められた. 位相マップは壁運動異常の位相遅延だけでなく, 伝導異常の評価にも有用な方法であった. 本法は心室各セグメントの種種の情報を3次元的に総合的に理解する方法として優れた表示法である.

AbstractA method for three-dimensional functional mapping of Tl-201 myocardial uptake, washout, wall motion and phase was developed using SPECT. Each parameter was mapped using polar display in the same format. Normal values were determined in Tl-201 exercise study in 16 patients. Myocardial counts were lower in the septum and inferior wall and the difference of counts between anterior and inferior walls were greater in man compared with the perfusion pattern in woman. Washout was slower at septum and inferior wall in man, and slightly slower at inferior wall in woman. In gated blood-pool tomography, length-based and count-based Fourier analyses were applied to calculate the parameters of contraction and phase. The results of both Fourier analyses generally agreed ; however, the area of abnormality was slightly different. Phase maps were useful for the assessment of asynergy as well as in patients with conduction disorders. These cardiac functional maps using SPECT were considered to be effective for the understanding of three-dimensional informations of cardiac function.
