Various morphologic criteria have been proposed to distinguish pleural from pulmonary parenchymal processes using CT. Although these criteria are helpful in most instances, they are not infallible. In a retrospective review of chest CT over a 1 1/2 year period, previously described signs were not sufficient to distinguish pleural from parenchymal disease in five patients who underwent routine contrast-enhanced CT. This was true in cases of large, localized areas of air-space disease and in cases of combined pleural and parenchymal disease. In these patients bolus intravenous contrast medium administration at the plane of major abnormality proved extremely useful for diagnosis by directly demonstrating pulmonary blood vessels and/or contrast enhancement in parenchymal processes.
已经提出了各种形态学标准，用于通过CT区分胸膜病变和肺实质病变。尽管这些标准在大多数情况下是有用的，但并非绝对可靠。在一项对1年半期间胸部CT的回顾性研究中，在5例接受常规增强CT检查的患者中，先前描述的征象不足以区分胸膜病变和实质病变。在大片局限性气腔病变以及胸膜和实质合并病变的病例中都是如此。在这些患者中，在主要异常层面进行静脉团注造影剂，通过直接显示肺血管和/或实质病变中的造影剂增强，对诊断非常有用。
