| Abstract | 「I. 緒言」 99mTc-Pyrophosphate (以下PYP) による急性心筋梗塞スキャンは, 急性心筋梗塞における心筋壊死の存在と広がり, 大きさの評価が可能であり陳旧性心筋梗塞においても, 心筋梗塞の再発の早期発見や心室瘤の診断に有用とされていた. しかし, 従来はその集積が急性心筋梗塞に特異的であると考えられたが, 最近PYPスキャンのnon-specificな集積が多く報告されるようになり, 特に心プールに一致するdiffuseな集積に対しては, 診断基準の見直しがせまられている. 今回われわれは, single photon emission computed tomography (以下ECT) を用い, γ-カメラでdiffuseな集積を示す急性心筋梗塞に対して, ECTによる局在診断の可能性を検討した. 「II. 対象および方法」 対象は昭和55年4月より56年3月までに, 市立敦賀病院内科に急性心筋梗塞として入院し, 発症1週間以内に99mTc-PYPスキャンをγ-カメラとECTで同時に行った7例である. |

| Abstract | [Summary] Scintigraphic visualization of an acute myocardial infarction (AMI) with technetium 99m-labeled pyrophosphate (Tc-PYP) has became a common diagnostic procedure in nuclear medicine and a valuable aid in workup for suspected myocardial infarction. However, this procedure is frequently hampered by the diffuse uptake of the tracer, which are a potential source of an erroneous diagnosis. We have performed single photon emission computed tomography (SPECT) to investigate the diffuse uptake of the heart on gamma camera images. Seven patients with AMI were studied. Two of them showed diffuse uptake of the heart on conventional gamma camera images, one was posterolateral infarction, other was right ventricle and left inferoposterior infarction. SPECT was performed soon after gamma camera study, all of them ovbious abnormal uptake in the myocardial lesions were identified. Two patients, who showed diffuse uptake on gamma camera images, revealed focal uptake without cardiac blood pool activity. From our result utilization of SPECT certainly makes it posible to separate myocardial abnormal activity from cardiac blood pool activity, which cause diffuse uptake on gamma camera images, and increased the specificity of the Tc-PYP myocardial scintigraphy in patients suspecious of AMI. |
