| 摘 要： | 目的探讨直接数字化X线摄影（DDR）诊断肺内孤立性结节的假阳性原因。方法回顾性分析32例DDR正侧位胸片诊断或可疑诊断肺内孤立性结节、MSCT对照均证实为假阳性的影像学资料。结果32例常规DDR胸片提示肺结节性病变，MSCT上与之对应为胸腔包裹积液2例，片状炎性病变1例，血管影6例，支气管内异物（钡剂）1例，局部胸膜肥厚4例，胸膜钙化2例，肺门淋巴结钙化2例，肺纤维索条重叠勾画3例，CT扫描正常结合透视为乳头影9例，结合体检为胸、背部软组织结节2例。结论加强DDR胸片诊断肺内孤立性结节假阳性原因的认识，可提高胸部影像学诊断肺内孤立性结节的准确性。

| Abstract: | Objective To evaluate the causes for false positive of solitary pulmonary nodules (SPN) diagnosed by direct digital radiography (DDR). Methods The imaging data of 32 cases of SPN misdiagnosed by DDR, and then MSCT identified as false positive SPNs were analyzed retrospectively. Results MSCT demonstrated that,32 SPNs suggested by routine DDR chest imaging were really 2 cases of thoracic encapsulated effusion, 1 case of patchy inflammatory affection, 6 cases of vascular shadow, 1 case of corpus alienum (baric... |
