| Abstract | 「要旨」123I-BMIPPシンチ(BMIPP)による急性心筋梗塞(AMI)のarea at riskの検出の可能性について検討した. AMI完全閉塞例13例に99mTc-tetrofosmin(TF)を投与し, 再灌流成功後7日以内のBMIPPと比較検討した. 欠損度は0〜3の4段階とし, SPECTは短軸断面16区画と長軸心尖部2区画の計18区画に分割した. 集積低下を呈した区画数の合計をextent score(ES)とし, 各区画の欠損度の総和をseverity score(SS)とした. ESはBMIPPで6.5±2.4, TFで7.5±2.4とTFが大で(P<0.01), BMIPP/TFは0.86±0.18であった. SSはBMIPPで16.2±6.0, TFで19.2±5.6と, TFが大きく(P<0.01), BMIPP/TFは0.83±0.18であった. 各区画におけるTFとBMIPPの完全一致率は85%で良好であった. 再灌流後早期に施行したBMIPPによる集積異常領域は, 再灌流前のTFと比較し, 範囲, 程度は若干少なく表示されることを念頭におけば, area at riskを推定できると考えられた. |

| Abstract | [Summary]The purpose of this study was to investigate the detection of area at risk of acute myocardial infarction (AMI) by 123I-BMIPP(BMIPP). 99mTc-tetrofosmin(TF) scintigraphy was performed on 13 patients with AMI with total coronary occlusion. BMIPP scintigraphy was done on the same patients within 1 week after successful reperfusion by direct PTCA. Activity of both tracers was scored in 8 basal, 8 midventricular and 2 apical segments, using a four-point grading system as defect score : 3=defect, 2=severely low uptake, 1=slightly low uptake, 0=normal. Extent score(ES) was defined as a total number of segment which deteriorated of uptake, and severity score(SS) was defined as a total score of defect score. ES of BMIPP was 6.5+2.4 and that of TF was 7.5+-2.4. ES of BMIPP was smaller than that of TF. A ratio of BMIPP/TF was 0.86+-0.18. SS of BMIPP was 16.2+-6.0 and that of TF was 19.2+-5.6. SS of TF was larger than that of BMIPP. A ratio of BMIPP/TF was 0.83+-0.18. A correlation of ES and SS between TF and BMIPP was excellent. BMIPP showed ischemic area by culprit lesion and infarct area clearly. We concluded that BMIPP could indicate area at risk. |
