| Abstract | 「要旨」虚血性心疾患患者19例を対象に, 13N-NH3および18F-FDGを用いたPositron Emission Tomography(PET)を施行し, 体軸断層像から心臓短軸, 長軸面垂直断層像および同心円表示を再構成し, 異常の有無を判定し, 判定の容易さを再構成画像間で比較検討した. 体軸断層像において, スライス面と平行になるため評価が困難であった前壁および下壁は, 短軸および長軸面垂直断層像を用いることにより, 病変の有無および範囲の評価が容易となった. さらに短軸像から, 血流と糖代謝それぞれの同心円表示を作成比較すると, "mismatch"の判定が容易となり, 虚血心筋, 梗塞心筋の定量的評価の可能性も示唆された. PETによる心筋血流, 糖代謝の三次元的評価は, 虚血性心疾患の診断および重症度の判定に有用であると考えられた. |

| Abstract | [Summary]To evaluate clinical value of three-dimensional assessment of cardiac PET image, oblique-angle tomograms and polar map displays were reconstructed from transaxial PET images using 18F-2-fluoro-2-deoxyglucose and 13N-ammonia in 19 patients with coronary artery disease. Short-axis and vertical long-axis images enabled to evaluate extent and severity of perfusion abnormality easily in the anterior and inferior regions which were tangental in the transaxial images. Using polar map displays, perfusion/metabolism mismatch may be more easily assessed. Thus, semiquantitative analysis of ischemic and infarcted myocardium may be permitted with PET studies. |
