| Abstract | 「要旨」201TlCl, 99mTc-MIBIの2核種を用いることにより運動負荷心筋シンチグラフィの所要時間の短縮を試みた. 以下に述べる4通りの検査プロトコールで各1例ずつ施行した. (A)法は安静時にTlを投与した後に運動負荷時にMIBIを投与して2核種同時収集を行うもの, (B)法は安静時にMIBIを投与後, 負荷を行いTlを投与して2核種同時収集を行うもの, (C)法は負荷時にMIBIを投与し, 1時間経過後に安静状態でTlを投与して2核種同時収集を行うもの, (D)法は安静時にTlを投与してTl像を撮像後, 運動負荷時にMIBIを投与してMIBI像を撮像するものである. 2核種同時収集の際にはTEW法によるクロストーク, 散乱線の除去を行った. 2核種の使用により検査時間は1-2時間程度に短縮された. また散乱線, クロストークの除去が正確な診断をするうえでは必要であると考えられた. |

| Abstract | [Summary] We carried out dual 201Tl/99mTc-MIBI imaging, to reduce the time required for exercise myocardial scintigraphy. We investigated 4 different protocols. In protocol (A), Tl was injected at rest followed by the injection of MIBI at peak exercise. Dual SPECT images were obtained by 201Tl/99mTc simultaneous acquisition. Protocol (B) means reverse either, in which MIBI was injected at rest followed by the administration of Tl at peak exercise. In protocol (C), exercise was performed first with MIBI-injection, and then Tl was injected at rest after one hour later. Simultaneous acquisition was also performed. In protocol (D), after the rest Tl-imaging, MIBI was injected at peak exercise, and then the MIBI-imaging was done. In protocol (A), (B) and (C), simultaneous acquisition was performed using TEW (Triple-Energy Window) scatter correction. Thanks to using dual isotopes, all procedures could be completed within 1-2 hours, which was much shorter than the conventional myocardial perfusion imaging. Scatter correction was useful for accurate diagnoses, when the simultaneous imaging is performed. |
