Localization of acute myocardial infarcts can be done directly by imaging 99mTc pyrophosphate in the infarcted myocardium, or indirectly by analysis of wall motion abnormalities. Combining these modalities improves the sensitivity and specificity of the study. Forth-nine consecutive abnormal studies were analyzed in which both wall motion and static images were obtained with a single injection of pyrophosphate. At least 50% of the acute infarcts were better localized (or additional information obtained) by combining the modalities.
急性心肌梗死的定位可通过对梗死心肌中的99mTc焦磷酸盐进行成像直接完成，或通过分析室壁运动异常间接完成。将这些方法结合起来可提高研究的敏感性和特异性。对连续49项异常研究进行了分析，这些研究中通过单次注射焦磷酸盐同时获得了室壁运动和静态图像。通过结合这些方法，至少50%的急性梗死得到了更好的定位（或获得了额外信息）。
