目的探讨16层CT血管造影(CTA)对下肢动脉硬化闭塞诊断价值。方法回顾性分析30例16层CTA检查资料,应用容积重建(VR)和最大密度投影(MIP)重建,曲平面重建(CPR)对下肢血管显示情况进行评价。结果 30例16层CTA的VR、MIP、CPR图像对下肢血管主干及其主要分支显示率100%,清晰显示了下肢血管狭窄程度、血管钙化。结论 16层CTA安全、快捷、简便且重建图像质量高,能为临床治疗提供详实的影像学资料,可以作为下肢动脉硬化闭塞患者的首选筛查方法。
Objective To investigate the value of 16-slice CT angiography (CTA) in the diagnosis of arteriosclerosis obliteration in the lower extremities. Methods A retrospective analysis of 30 cases of 16-slice CTA examination data was performed by using volume reconstruction (VR), maximum density projection (MIP) reconstruction and curve plane reconstruction (CPR). Results The VR, MIP and CPR images of 30 cases of 16-layer CTA displayed 100% of the lower extremity vascular trunk and its main branches, clearly showing the degree of lower extremity vascular stenosis and vascular calcification. Conclusion The 16-slice CTA is safe, fast and easy to reconstruct, which can provide detailed imaging information for clinical treatment. It can be used as the screening method of choice for patients with lower extremity arterial occlusive disease.
