目的探讨64层螺旋CT血管成像技术对主动脉病变的诊断及临床应用价值.方法 32例主动脉病变患者行64层螺旋CT扫描,并对原始数据采用多平面重组(MPR)、曲面成像(CPR)、最大密度投影(MIP)、容积再现(VR)、高级血管分析(AVA)处理.32例主动脉病变均经临床、手术证实.结果 32例主动脉病变中,主动脉夹层16例、假性动脉瘤7例、真性动脉瘤4例、主动脉弓缩窄3例、主动脉离断2例.MPR对内膜破口、附壁血栓显示较佳.内膜片及初始破口显示率为81%(13/16),7例假性动脉瘤周围血栓,显示率100%(7/7);CPR简单、直观显示病变全程,显示率100%(32/32);MIP对钙化及管径精确测量颇有价值,显示率84%(27/32);VR能明确病变的范围和周围血管关系,显示率100%(32/32);AVA对测量血管管径、血管横截面积具有意义,显示率44%(14/32).结论 64层螺旋CT血管成像技术对主动脉病变的诊断具有重要意义.

Objective To explore the value of the 64-slice spiral CT angiography(SCTA)in diagnosis of aortic disease.Methods 32 cases with aortic diseases confirmed by operation underwent 64-slice spiral CT enhanced scan,raw data were dealed with multiplanar reformation(MPR),curved plannar reformation(CPR),maximum intensity projection(MIP),volume rendering(VR)and advantage vessel analysis(AVA).Results The aortic disease in 32 cases included aortic dissection in 16 cases,pseudoaneurysm in 7 cases,true aneurysm in 4 cases,narrowing of the aortic arch in 3 cases and amputation of aortic arch in 2 cases.The endometrial break and mural thrombus better showed with MPR and the detecting rat of intimal flake and the initial break was 81%(13/16),while for the periphery thrombosis in 7 cases with pseudoaneurysm,the detecting rate was 100%(7/7).The showing rate for displaying the whole with CR was 100%(32/32).In showing calcification and accurate of vessels with MIP,the detecting rate was 84%(27/32).The showing rate of the extent of the disease and the relationship between peripheral vascular was 100%(32/32).AVA was of significance in the measurement of vascular diameter and vascular cross-sectional area,the showing rate was 44%(14/32).Conclusion 64-slice spiral CT angiography is of significance in diagnosing aortic diseases.
