摘要
目的评价16排螺旋CT血管造影在下肢动脉血管疾病诊断中的临床应用,并在动脉清晰度、敏感性、特征型、准确性等方面与DSA做对比分析。方法回顾性分析42例下肢动脉疾病患者的影像资料并结合临床治疗,所得薄层图像传入后处理工作站,进行多种形式重建,结果42例患者中,由于动脉硬化引起的腹主动脉及下肢动脉闭塞及狭窄32例,血栓闭塞性脉管炎10例。在动脉清晰度方面,CTA较DSA显示清晰,但两者相比无明显差异(P≥0.05)。CTA的敏感性、特征性和准确性随着病变血管的变细而降低,有差别但无明显差异(P≥0.05)。结论 16排螺旋CT血管造影可应用于筛选和发现病变,对严重下肢动脉狭窄及闭塞患者的术前评价有很大帮助。
Objective To evaluate the clinical application of 16 Slices Spiral CT in the diagnosis of lower extremity arterial disease and two methods were compared in the definition,sensitivity,specificity,accuracy.Methods 42 confirmed patients of lower extremityarterial disease received CTA(Computed tomography angiography) examinations and clinical treatment.We used workstation for 3D reconstruction.Results VR and MIP findings on 16-MSCT angiography were as follows,32 abdominal aortic and lower extremity arterial stenosis or occlusion due to mural calcification,10 due to thromboangiitis obliterans.Conclusion CTA might be used in primarily detecting lower extremity arterial stenosis or occlusion,it should have great help to serious lower extremity arterial stenosis or occlusion.
