Abstract「要旨」虚血性心疾患21例に対し, 99mTc-methoxyisobutyl isonitrile (MIBI) 心拍同期心筋SPECTデータを用いた心機能解析を行い, その臨床的有用性につき検討を行った. MIBI投与1時間後よりPICKER/島津社製三検出器型ガンマカメラPRISM 3000を用い, 1方向70心拍, 6度ごと20方向 (×3) の360度データ収集を行い, 拡張末期 (ED) および収縮末期 (ES) 像を極座標上に展開した. 両極座標より, 左室収縮に伴う心筋count densityの上昇度として%WT (ES count-ED count/ED count × 100) を算出し, 心機能指標とした. %WTは左室カテーテル造影検査 (LVG) により算出したLVEFと良好な相関を示し (r=0.85) , 局所の%WTもLVGならびに心エコーにより得られた局所壁運動をよく反映していた. 三検出器型ガンマカメラシステムを用いることによりデータの収集および解析を短時間で行うことができ, 臨床的に有用な検査法と考える.

Abstract[Summary] Twenty-one patients with ischemic heart disease were studied by resting 99mTc-methoxyisobutyl isonitrile (MIBI) gated SPECT images using a 3 head rotating gamma camera (Picker/Shimadzu:PRISM 3000) . The data were aquired over 360°in 20 (×3) steps, each of which was 70 beats. The systolic wall thickening index (%WT) was calculated as (ES count-ED count/ED count×100) , using the circumferential profile analysis of ED and ES short axial images. The %WT was correlated well with LVEF obtained from contrast ventriculography (r=0.85, n=17) . By using high speed (3 head) rotating gamma camera, we have shortened the time of collecting MIBI gated SPECT data, and this method can provide useful information on ventricular function.
