| Abstract | 「要旨」心筋炎急性期の2症例に対し[99mTc]-pyrophosphate, [201Tl]-chloride dual isotope SPECTを施行し, これを重ね合わせカラー表示したところ炎症の部位と広がりを明確に表示し得たので報告する. 「I. はじめに」心筋炎の急性期において[99mTc]-pyrophosphate (PYP)による心筋イメージングがその診断に有用であるが, planar像では炎症の部位や範囲を同定し, 重症度を診断することは困難な場合もあった. 近年[99mTc]PYPと[201Tl]Clによる2核種同時収集法([99mTc]PYP, [201Tl]Cl, dual isotope SPECT-以下dual SPECT)が開発され, また廣江らにより[99mTc]PYPイメージと[201Tl]Clイメージを重ね合わせてカラー表示する方法が考案され, 心筋梗塞における梗塞部位や範囲の同定, 心内膜下梗塞や梗塞部周囲の虚血領域の診断により有力な情報を提供することが可能になってきた. |

| Abstract | [Summary] [99mTc]-pyrophosphate (PYP) and [201Tl]-chloride dual isotope single photon emission computed tomography (SPECT) is now available to detect the site and extent of acute myocardial infarction. In inflammatory myocardial disease, [99mTc]PYP makes hot image on damaged area. We performed dual isotope SPECT of [99mTc]PYP and [201Tl]Cl in two patients with acute myocarditis and severe rhythm disturbance to evaluate the severity of inflammation. Myocardial damage was estimated by [201Tl] perfusion coloring blue and myocardial inflammation was estimated by [99mTc]PYP uptake coloring red. The overlap display of both images made it clear to detect spatial extent of myocardial inflammation. Using this technique, we expect to estimate the severity of myocarditis and to make a decision of therapeutic plan. |
