Abstract「要旨」 14例の急性心筋梗塞 (発症2〜10日) に, 通常の2次元の99mTc-ピロリン酸心筋シンチグラムを施行後, 回転型ガンマカメラによるエミッションCT (ECT) を施行し, その有用性を検討した. ECTは全収集時間が12分以内で, 再構成像は, 横断面のほか, LAOよりみた心臓の前額面, RAOよりみた心臓の矢状面のおのおのに多層の断層像を得た. いずれも心筋異常集積部と骨との分離が可能であり, 14例全例に心筋に限局した集積が明らかであった. 特に2次元シンチグラムでびまん性集積を示した6例 (43%), およびドーナツ状を呈した1例 (7%) では, ECTのおのおのの断面からの評価により病巣の局在診断が明らかとなった. 99mTc-ピロリン酸心筋ECTは, 急性心筋梗塞の診断精度を上げるとともに, 病巣の位置や広がりを立体的に知る上できわめて有用な検査法と考えられた.

Abstract[Summary] 99mTc-pyrophosphate (PYP) myocardial emission computed tomography (ECT) was performed following the conventional planar imaging in 14 cases with acute myocardial infarction. Cardiac short axis planes (LAO view) and long axis planes (RAO view) were also reconstructed from a series of transaxial planes for three-dimensional evaluation of 99mTc-PYP accumulation. While the planar imaging reveals diffuse pattern of myocardial uptake in 6 cases (43%) and doughnut pattern of uptake in 1 case (7%), ECT imaging shows focal pattern of myocardial uptake in each of 14 cases. In ECT imaging, myocardial uptake was more delineated by the separation from the bone activity. We conclude that ECT imaging can provide topographical informations of 99mTc-PYP myocardial accumulation accurately, especially in case of diffuse pattern uptake by the planar imaging.
