| Abstract | 「要旨」 Tl-201心筋SPECT像より極座標を使って, 単位面積あたりのTl-201分布と平均距離を求め, Bull's-eye表示と, 立体3次元分布再構築像のシネモード回転表示を行った. 負荷と安静時再分布像より, Tl-201集積の段階評価をし, 冠動脈造影で得た所見をgold standardとして, 冠動脈狭窄に対する診断能を調べ, ROC曲線を描いた. 冠動脈造影で得られた狭窄度と, Tl-201集積評価との間の相関は, 1枝, 2枝病変については高いものの, 3枝病変については低く, 病変血管の同定はできなかった. Tl-201心筋立体像を作ることで, 歪みの少ない, より実際に近いTl-201の分布を知ることが可能になり, 心尖部心基部周囲のTl-201集積評価も容易になると考えられた. |

| Abstract | [Summary] Three dimensional images (3D Model) and Bull's-eye maps of Tl-201 stress and redistribution scintigrams were reconstructed from average distances and relative accumulations per unit area. 3D Models viewed from different angles were studied in cine mode, in conjunction with the Bull's-eye map. The accumulations of Tl-201 were classified into five different ranks. ROC curves for 3D Model were computed. The coronary artery stenoses estimated by 3D Model were found to have statistical correlations with the results of coronary angiography, in one and two coronary vessel disease, but not in three. Concerning the areas and the locations of abnormal Tl-201 distributions, 3D Model images offer more comprehensible informations than the conventional Bull's-eye method, especially around the left ventricular outlet. |
