| Abstract | 「要旨」SPECT(Single Photon Emission Computed Tomography)を用いた201TlClによる心筋シンチグラムの定量解析について, 視覚的診断と対比しながら臨床的検討を行った. 定量解析法に関しては基礎的検討ですでに述べたとおりであるが, 今回さらに側壁梗塞の再標準化プログラムを追加した. この再標準化は特に左回旋枝領域の病変の検出に有用であった. 心筋梗塞の診断精度は, 心筋SPECT定量診断・SPECT視覚的診断・Planar視覚的診断の順に優れていた. 梗塞部位別の検討では, 前壁梗塞はSPECT視覚的診断も定量的診断に匹敵する良好なsensitivityを示したが, 下後壁梗塞は定量的診断の方が優れたsensitivityを示した. 一方正常正診率(specificity)に関しては, 定量的診断は視覚的診断よりやや低かった. また定量解析を用いた梗塞マップは, 梗塞の部位・範囲・拡がり・程度を耐本的に把握できるため, 梗塞の責任冠動脈病変の推定がより正確かつ容易となった. |

| Abstract | [Summary]Clinical evaluation of the quantitative analysis of Tl-201 myocardial tomography by SPECT (Single Photon Emission Computed Tomography) was performed in comparison with visual evaluation. The method of quantitative analysis has been already reported in our previous paper. In this study, the program of re-standardization in the case of lateral myocardial infarction was added. This program was useful mainly for the evaluation of lesions in the left circumflex coronary artery. Regarding the degree of diagnostic accuracy of myocardial infarction in general, quantitative evaluation of myocardial SPECT images was highest followed by visual evaluation of myocardial SPECT images, and visual evaluation of myocardial planar images. However, in the case of anterior myocardial infarction, visual evaluation of myocardial SPECT images has almost the same detectability as quantitative evaluation of myocardial SPECT images. In the case of infero-posterior myocardial infarction, quantitative evaluation was superior to visual evaluation. As for specificity, quantitative evaluation of SPECT images was slightly inferior to visual evaluation of SPECT images. An infarction map was made by quantitative analysis and this enabled us to determine the infarction site, extent and degree according to easily recognizable patterns. As a result, the responsible coronary artery lesion could be inferred correctly and the calculated infarction score could be correlated with the residual left ventricular function after myocardial infarction. |
