64层螺旋CT三维重建技术对下肢动脉粥样硬化病变的显示

目的探讨64层螺旋CT三维重建技术对下肢动脉病变的显示。方法103例下肢动脉粥样硬化的患者行64层螺旋CT血管造影检查资料在工作站进行多种三维重建,分析其影像表现。结果103例患者均获得了成功的造影图像,2459根下肢动脉血管得到了显示。其中845根(34.4%)下肢动脉血管正常;672根(27.3%)轻度狭窄;327根(13.3%)中度狭窄;292根(11.9%)重度狭窄,323根(13.1%)下肢动脉血管闭塞。结论64层螺旋CT三维重建是又一种无创性的、可靠的、简便的检查下肢动脉粥样硬化的方法,具有较高的临床价值。

64 Multi-slice Spiral CT 3D Reconstruction in Lower-extremity Arteriosclerosis Obliterans

Objective To evaluate 64 Multi-slice spiral CT 3D reconstruction in displaying lower-extremity arteriosclerosis obliterans.Methods 64 Multi-slice spiral CT scanning was performed in 103 patients with lower-ex- tremity arteriosclerosis obliterans.3D image reconstruction was carried out.Results Excellent 3D reconstructed images were obtained in 103 cases,2459 vessel segments were evaluated.845 of them were normal (34.4%),672 of them were mild stenosis(13.3%),327 of them were moderate stenosis(11.9%),292 of them were severe stenosis,323 of them were occluded.Conclusion 64 slice spiral CT 3D reconstruction is another accurate and non-invasive diagnostic method for lower-extremity arteriosclerosis obliterans,thus,it is of high value in clinical practice.
