摘要
目的：９９ｍＴｃ－ＮＯＥＴ再分布显像评价心活力的作用。材料和方法：６７例冠心病（ＣＡＤ）患者进行９９ｍＴｃ－ＮＯＥＴ运动及２ｈ再分布心肌灌注显像，其中１２例行４～６ｈ再分布显像，３例ＰＴＣＡ术后１个月静息显像。结果：９９ｍＴｃ－ＮＯＥＴ ２ｈ再分布显像示 ６８３％（８４／１２３）心肌节段有明显的再分布，其中７７．４％（６５／８４）心肌节段完全充填。４～６ｈ再分布显像示２ｈ时部分充填的心肌节段３７．５％（３／８）完全充填，无充填的４个节段仍无变化。 ＰＴＣＡ术后显像示术前所有异常的节段（６个有再分布和 １个无再分布节段）均大致上常。结论：９９ｍＴｃ－ＮＯＥＴ有明显的再分布特征，可用于心肌活力的研究，方法简便。
To study the value of 99mTc-NOET redistribution imaging in evaluating myocardial viability. Materials and Methods: 67 patients with CAD underwent exercises and 2h redistribution 99mTc-NOET imaging, 12 patients also underwent 4-6h imaging, 3 patients underwent rest imaging I month post -PTCA. Results: Redistribution imaging in 2h showed that 68.3% (84/123) segments had obvious radioactive fillsin, of those, 77.4% (65/84) fully fills-in. Redistribution imaging in 4-6h showed that 37.8% (3/8) segments became fully filling-in (partly filling-in in 2h redistribution) and 4 segments with monredistribution did not change any more. Rest imaging post -PTCA showed that all abnormal segments (6 reversible defect and 1 permanent defect) became almost normal uptake. Conclusion: 99mTc-NOET had obvious redistrbution properties. It seemed that it was an easy way to use for evaluating myocardial viability.
