目的：探讨双源 CT 锁骨下动脉成像在临床诊断中的应用。方法收集2012年7月～2014年5月我院双源CT 锁骨下动脉成像检查的27例患者数据资料，采用多种后处理技术：最大密度投影（MIP）、容积再现（VR）、多平面重组（M PR）及曲面重建（CPR）等处理。观察锁骨下动脉的走行，管腔病变情况。结果锁骨下动脉正常2例；检出粥样斑块14例，其中混合斑块7例、非钙化斑块4例、钙化斑块3例，斑块位于开口处9例，近段5例；管腔闭塞5例，均位于开口处；夹层病变3例，均为开口处，受累于主动脉夹层；血管走行异常2例，均为右侧，绕行于胸骨上窝；粥样斑块行支架术后1例。结论双源 CT 血管成像技术无创、便捷、经济，联合多种后处理技术能充分显示锁骨下动脉的走行、明确诊断管腔有无病变、了解管腔外血管周围的情况，对临床制定下一步诊疗方案有重要的价值。

Objective To discuss the application of double‐source CT in arteriae subclavia imaging in clinical diagnosis . Methods We collected the data of 27 patients who had received the dual‐source CT arteriae subclavia imaging in our hospi‐tal from July 2012 to May 2014 .Various kinds of settling techniques such of MIP ,VR ,MPR and CPR were observed . The line of arteriae subclavia and pathological changes of lumen were ebserved .Results The arteriae subclavia of two ca‐ses were normal ;14 cases were diagnosed with atheromatous plaque ,including 7 cases with mixed plaque ,4 cases with non‐calcified plaques ,3 cases with calcified plaque ,9 cases with plaque on the opening part ,5 cases with plaque on the closing part ,5 cases with lumen blocking on the opening part ,3 cases with mezzanine lesion on the opening part suffering from aortic dissection ,2 cases with abnormal vessel line on the right sides rounding the suprasternal fossa ,1 case with atheromatous plaque after stenting operation .Conclusion Dual‐source CT in arteriae subclavia imaging technique is nonin‐vasive ,convenient and economic .After combining with various settling techniques ,it can fully display the lining of arteri‐ae subclavia ,clarify a diagnosis if there is lesion in the lumen ,and indicate the condition around the lumen perivascular ar‐ea .It has great value on making further clinical diagnosis plan .
