螺旋CT血管造影诊断主动脉瘤的临床应用价值

目的探讨多层螺旋CT血管造影在诊断腹主动脉瘤中的应用价值。方法收集我院腹主动脉瘤患者44例，均行多层螺旋CT扫描检查后，采用不同重建方式进行图像后处理，观察病变部位影像学特征。结果44例患者均能够显示清晰瘤体以及周围血管与瘤体的位置关系，且可观察附壁血栓并能准确测量动脉瘤的三维数据。本组44例腹主动脉瘤患者螺旋CT血管造影资料显示，均存在附壁血栓症状，其中，合并髂动脉瘤4例，有动脉瘤破裂迹象4例。多平面重建可清晰显示动脉瘤局限部位及其与周围组织、血管解剖关系，而最大密度投影法、容积再现技术能进一步对管腔各段较精确测量。结论螺旋CT血管造影扫描检查腹主动脉瘤具有操作简便、快速、直观及诊断准确等特点．县一种腹丰动脉瘤有效的榆杏方法．

Clinical application value of spiral CT angiography in diagnosis of aortic aneurysm

Objective To explore the application value of multislice spiral CT angiography in the diagnosis of abdominal aortic aneurysm.Methods 44 patients with abdominal aortic aneurysm in our hospital were selected to receive multislice spiral CT scanning,after which different reconstruction methods were used for image post-processing and the imaging characteristics of lesions were observed.Results All the 44 patients showed clear aneurysm and the location relationship between surrounding vessels and aneurysm.The mural thrombus could be observed and the three-dimensional data of aneurysm could be accurately measured.The spiral CT angiography data of 44 patients with abdominal aortic aneurysm showed that mural thrombus symptoms were found in all the patients.Among them,4 patients had combined iliac aneurysm and 4 patients had aneurysm rupture signs.Multi-planar reconstruction could clearly show the location of aneurysm and its relationship with surrounding tissue and vessels.And the maximum intensity projection method and volume rendering technique could further measure the segments of lumen more accurately.Conclusion Spiral CT angiography is easily operative,fast,clear and accurate in the examination of abdominal aortic aneurysm,thereby is an effective examination method in the diagnosis of abdominal aortic aneurysm.
