摘　　要：目的:观察64排螺旋CT多期增强扫描联合血管成像对肺内肿块的影像学特征,探讨其在临床确诊时的意义。方法:收治肺内肿块患者48例,平均分为肺癌组和良性病变组。对所有患者采用64排螺旋CT胸部平扫,Ⅲ期增强。对供血动脉进行三维重建,了解支气管动脉与肿块的空间毗邻关系,评价肿瘤血管血供情况。结果:肺癌组主要供血来源于供血支气管动脉,部分来源于体动脉供血,且CT显示率显著高于良性病变组(P<0.01)。肺癌组CT增强峰值显著大于结核球组、炎性假瘤组及错构瘤组(P<0.05)。肺癌组与良性病变各组间的增强动态曲线不同,各组达到峰值和回落的时间有特异性。结论:肺内肿块的CT多期增强扫描联合血管成像技术,可以准确提供肺内肿块在各增强扫描时相中的特点,客观显示肿块中血管形态、数量及血供的改变情况。Objective:To observe the imaging features of 64 slice spiral CT multiple phase enhanced scanning combined with vascular imaging for pulmonary mass and explore its significance in clinical diagnosis.Method:48 patients with pulmonary mass were selected.They were randomly divided into the lung cancer group and the benign lesion group.All the patients received 64 slice spiral CT chest plain scan,and the Phase Ⅲ enhanced.We made three-dimensional reconstruction for feeding artery,understood the spatial adjacency relationship between the bronchial artery and the tumor,and evaluated the blood supply of tumor.Results:The main blood supply of the lung cancer group was supplied from the blood supply of the bronchial artery, and partly from the body blood supply.The CT display rate was significantly higher than that in the benign lesion group(P<0.01).The CT enhanced peak value of the lung cancer group was significantly greater than that of the tuberculoma group,the inflammatory pseudotumor group and the hamartoma group(P<0.05).The enhanced dynamic curve of the lung cancer group and the benign lesion group were different;the time of peak and fall of each group were specific.Conclusion:The technology of CT multiple phase enhanced scanning combined with vascular imaging for pulmonary mass can accurately provide the characteristics of pulmonary mass in the enhanced scanning phase,objectively display the changes of blood vessel shape,quantity and blood supply in the pulmonary mass.
