目的探讨64层CT血管成像诊断下肢动脉硬化闭塞症的方法和临床价值。方法对30例临床诊断为下肢动脉硬化闭塞症的患者行64排螺旋CT血管成像检查,对所有扫描原始数据行积再现,最大密度投影,冠状、矢状面多平面重组以及曲面重建。结果 30例患者CT血管成像检查均能清晰显示动脉血管影像,可以准确显示下肢动脉硬化病变血管情况。结论 64层CT血管成像能清晰地显示下肢动脉及其病变,对术前诊断及术后评价具有很高的临床价值。
Objective To explore the method and clinical value of 64-slice CT angiography in the diagnosis of arteriosclerosis obliterans in lower extremities. Methods Thirty patients diagnosed as arteriosclerotic lower extremity arteriosclerosis were examined by 64-slice spiral CT angiography, and all the original data were plotted and plotted. The maximum density projection, coronal and sagittal plane reconstruction and surface reconstruction were performed. Results 30 cases of CT angiography examination can clearly show the arterial image, can accurately show the lower extremity arteriosclerosis vascular lesions. Conclusion 64-slice CT angiography can clearly show the lower extremity arteries and their pathological changes. It has high clinical value in preoperative diagnosis and postoperative evaluation.
