| Abstract | 「I. はじめに」 急性心筋梗塞に対する99mTc-PYPシンチと201TlClシンチの診断的意義は高く, 現在, 広く用いられている. しかし, SPECTを行っても, Tc-PYPの集積部位が解剖学的に心臓のどの部位にあるのか, 判断に困る場合も多い. 著者らは急性心筋梗塞に対してTc-PYPとTlClを投与し, 二核種同時収集プログラムを用いることにより, 同時に二つのSPECT像すなわちDual energy SPECT像 (以下D-SPECT像) を得ている. 今回, その診断的意義について検討したので報告する. 「II. 装置」 GE社製Maxi star systemを使用し, 二核種同時収集プログラムを利用した. 本プログラムを用いると, 異なるエネルギーピークをもった二核種の放射性医薬品のデータを同時に収集することが可能である. 収集されたデータは別々の記憶装置上 ($1, $2) に保存され, これらのデータから, 異なる二核種のSPECT像を構成することも可能である. |

| Abstract | [Summary] Myocardial scintigraphy with Tc-99m PYP is useful for detection of acute myocardial infarction. But sometimes it is difficult to analyse the infarcted site even in the SPECT images. In such cases, Tl-201 scintigraphy has been performed later on the realize the site. We used new method to take Tc-PYP and TlClSPECT images simultaneously in 16 patients with acute myocardial infarction. Tc-PYP (20 mCi) and TlCl (2-3 mCi) were administered intravenously 3 hours and 5 minutes each before the dual energy myocardial SPECT. Acquisitions were made over 30 angular projections (180) at 30 sec to 40 per projection. Using dual energy technique of Maxi star system, positive Tc-PYP images, negative TlCl images and both added images were obtained simultaneously on the one film. Fourteen of 16 AMI cases, successful data were obtained. Especially in one case, we could detect acute and old infarcted sites very easily with this dual energy SPECT method. The advantages of this method are : (1) no movement of positioning (2) shortage of examination time in the severely ill patients (3) easily differentiate between acute and old infarcted sites. |
