Fifty-five patients with old (9 days to 10 yr) transmural infarcts but with no evidence of recent infarction, were imaged with Tc-99m pyrophosphate. Discrete uptake was rare in the setting of an old infarct. Diffuse uptake was neither sensitive to, nor specific for, acute infarction. Prior infarction will rarely cause diagnostic error if the discrete pattern is required for a positive diagnosis.
55例有陈旧性（9天至10年）透壁性梗死但无近期梗死证据的患者，接受了锝-99m焦磷酸盐显像。在陈旧性梗死情况下，离散性摄取很少见。弥漫性摄取对急性梗死既不敏感也无特异性。如果阳性诊断需要离散模式，既往梗死很少会导致诊断错误。
