CT与超声在肺周围型占位病变诊断中的协同定性价值

目的 应用CT、二维及彩色多普勒超声诊断肺部周围型肿块的性质。方法 回顾分析50例经病理证实的肺部肿块CT及超声特点。其中肺癌36例、炎性肿块14例。结果 CT上以肿块的边界、毛刺、分叶、密度、空泡征、血管集束及增强为依据，其诊断准确率为72％(36／50)；而超声则以肿块的形态，内部回声、小支气管显示率及血流改变为二者的鉴别依据，其诊断准确率为74％(37／50)，二者协同其诊断准确率为74％(44／50)。结论 CT与超声结合在肺周围型占位病变中有较高的定性价值。

The evaluation of CT combined with ultrasonography in qualitative diagnosis of the peripheral space occupying lesion in lung

Objective To evaluate CT, 2 dimensional and colored Doppler ultrasound in diagnosing peripheral space occupying lesion in lung. Methods CT and ultrasound manifestation of 50 cases with peripheral space occupying lesion (36 pulmonary carcinoma and 14 inflammatory mass), verified by pathology , were retrospectively analyzed. Results CT manifestation was characterized by boundary, spicule, lobulated appearance, density, vacuolation, predorminant vascularity and enhancement. And the rate of accuracy was 76%(36/50) in diagnosis. ultrasonographic manifestation was identified by appearance of mass, echo of the internal structures, revealed small bronchus and altered blood flow. The rate of accuracy was 74%(47/50). The rate of accuracy was 88%(44/50) when the diagnosis was made by ultrasound combined with CT. Conclusion CT combined with ultrasound is valuable in diagnosing peripheral space occupying lesions in lung.
