Abstract「I. はじめに」[99mTc]pyrophosphate(PYP)心筋イメージングは急性心筋梗塞症や急性心筋炎の診断に有用な手段である. さらにsingle photon emission computed tomography(SPECT)の導入後には梗塞巣の正確な部位診断や定量的評価が可能となってきている. しかしこのSPECT像によっても部位診断が困難な症例や再構成のさい心臓軸の決定がしにくい症例がみられる. 最近[99mTc]PYPと[201Tl]Clによる2核種同時収集法(dual isotope SPECT)が開発され, 本症の確定診断に応用がなされている. 本研究ではこのdual isotope SPECT像による梗塞巣をより容易, 確実に同定する目的で, カラー表示による梗塞機能図の作製を試みたので報告する. 「II. 方法」「1)SPECT法」装置には低エネルギー型高分解能コリメータを装着した東芝社製デジタルガンマカメラとデータ処理コンピュータ(GCA-90B)を使用した.

AbstractIn 12 patients with acute myocardial infarction, a dual isotope SPECT was applied to describe a myocardial infarct map for detecting the site and the extent of the infarct. Threshold cut-off level was determined as 55% for [99mTc] and 35% for [201Tl] according to cardiac phantom studies. Multiple cardiac tomograms showed two different uptakes of the isotopes in indentical slices and regions. Then, color tomograms were described on the red and green image for [99mTc] and for [201Tl], respectively, and Bulls eye map was drawn in the two colored fashion as the myocardial infarct map. In all patients, the infarct map was successful to determine the exact site of the infarct and the overlapped area by the viable myocardium. In conclusion, this functional map of acute myocardial infarction may be useful for understanding three dimensional area of the infarct and the viable myocardium easily and exactly.
