| Abstract | 「要旨」 運動負荷Thallium-201 (Tl-201) 心筋Single Photon Emission Computed Tomography (SPECT) を用いて右室壁の定量評価を正常例において試みた. 正常者12例に坐位エルゴメータによる多段階運動負荷を行い, 心筋SPECTを施行した. 短軸像のなかで右室壁が描出されているスライスを選出し, ROI法にて右室壁・左室壁を分離し, 心筋円周プロファイル (circumferential profile) 法にて右室・左室の10°ごとの相対的摂取率カーブ (RV-LV curve) 法を作成した. 正常者12例より求めた正常域 (平均±2標準偏差) は, 右室自由壁が左室最大値の30.1〜38.6%で偏差も小さく, 右室の定量評価に有用性が示された. |

| Abstract | [Summary] Although many studies of quantitative analysis of left ventricular myocardial wall (LVMW) have been reported using stress thallium-201 (Tl-201) , few reports of right ventricular myocardial wall (RVMW) have been estimated. In this study we determined whether single photon emission computed tomography (SPECT) with Tl-201 could accurately define normal range of RVMW in normal subjects. Twelve persons who have no valvular disease, nor coronary artery disease were included in this study. Stress SPECT study was reconstructed to make a short axial images of ventricles. RVMW and LVMW were flagged by mamual. Each ventricle was divided into 36 parts at every 10 degree. Relative activity counts in each ventricle were calculated as a percent counts of maximum counts in left ventricle. The normal range of RVMW with stress SPECT was as follows : anterior wall (33.2+-11.4%, mean +-2 standard deviation, -62.7+-18.4%) , free wall (30.1+-12.4% -38.5+-8.8%) , inferior wall (40.4+-7.8% -60.0+-21.4%) , septal wall (65.2+-17.2% -71.1+-14.2%) . Above the results, SPECT with Tl-201 can accurately define the normal range of RVMW, and this method is usefull to quantify the degree of ischemia and hypertrophy in RVMW. |
