肺内炎性肿块与周围型肺癌的CT及X线鉴别诊断

目的探讨肺内炎性肿块与周围型肺癌的CT及X线影像学表现特征及鉴别要点。方法对手术病理确诊的56例肺内炎性肿块和96例周围型肺癌病例的临床和CT及X线影像学资料进行回顾性分析。根据病灶形态分为典型肿块和不典型肿块。结合临床病史及影像学检查特征,对两者进行鉴别诊断。结果以形态分类为标准,诊断炎性肿块的敏感度、特异度、准确度分别为69.6%(39/56)、67.7%(65/96)、68.4%(104/152)。结合临床病史及影像学特征修正诊断的敏感度、特异度、准确度分别为80.4%(45/56)、74.0%(71/96)、76.3%(116/152)。结论以病灶形态为基础,结合临床病史,对影像学特征进行分析可明显提高诊断的敏感度、特异度及准确度。

The Differential Diagnosis of Pulmonary Inflammatory Mass and Peripheral Lung Cancer by CT and X-ray

Objective To investigate the imaging feature and essential spoints of differential diagnosis of pulmonary inflammatory mass and peripheral lung cancer by computed tomography and X-ray. Methods 56 patients of pulmonary inflammatory masses and 96 patients of peripheral lung cancers were included in the study,all patients conformed by pathology .The lesions were divided into typical and atypical masses according to morphology. Observing the signs of lesions and combining with clinical data. Results According to the standard of morphology,the diagnosis sensitivity,specificity and accuracy of inflammatory mass are 69.6%(39/56),67.7%(65/96)and 68.4%(104/152) respectively. The ameliorated sensitivity,specificity and accuracy are 80.4%(45/56),74.0%(71/96) and 76.3%(116/152) respectively. Conclusion The method of making morphology as basement and imaging feature as supplement can improve the sensitivity,specificity and accuracy of diagnosis.
