摘　　要：【目的】探讨16排螺旋CT仿真内窥镜(CTVE)成像对动脉病变的显示能力及临床应用价值。【方法】对40例动脉病变(包括动脉瘤18例,肺动脉栓塞6例,动脉闭塞16例)进行CTVE成像,其中手术证实12例,22例进行了DSA检查,6例肺动脉栓塞经B超及溶拴治疗得到证实,采用t检验进行统计学分析。【结果】40例动脉病变均获得了满意的CTVE图像,良好的显示了动脉内腔、内膜、附壁血栓、钙化斑块、血管狭窄及动脉夹层及动脉瘤破裂口的形态大小与正常血管的解剖关系。CTVE成像对动脉病变的显示能力对照DSA、手术、及内科证实的病例具有一致性,40例动脉病变CTVE总的显示率为80%(32/40)。【结论】CTVE成像能较好的显示血管腔内的情况,结合二、三维成像可明确诊断多种动脉疾病,对于选择治疗方法、指导临床手术、观察术后疗效及随访具有重要的应用价值。【Objective】To evaluate the display ability and the clinical application of 16-slice spiral CT virtual endoscopy(CTVE) in the diagnosis of arterial diseases.【Methods】Forty patients(include 18 patients with aneurysm,6 patients with pulmonary embolism,16 patients with arterial occlusion)were examined by CT virtual endoscopy.Twelve patients were confirmed by operation.Twenty-two patients had DSA for comparison.Six patients with pulmonary embolism were confirmed by ultrasound and treatments.【Results】Forty patients showed CT virtual endoscopy images successfully.CT virtual endoscopy images could clearly show the inner wall and inner structures of arteries,mural thrombus,calcification form,stenosis of vessels,the true and false lumina of aortic dissections,the lesion of false aneurysm,and the anatomic relationship between the lesion and surrounding structures of the normal vessels.Thirty-two patients revealled arterial diseases by CTVE in forty patients(80%).【Conclusion】16-slice spiral CT virtual endoscopy(CTVE) could provide more information of the artery by displaying the inner wall and allowing users to map the artery in a display.It is helpful in correct diagnosis and guiding surgery.
