摘要
目的分析西门子双源螺旋CT血管成像在诊断头颈部血管疾病中的临床价值。方法选取我院2017年12月~2018年4月179例高度可疑头颈部血管性疾病患者,进行双源螺旋CT血管造影,应用MPR、CPR、MIP、VR对西门子双源螺旋CT血管造影成像,分析成像结果。结果 69例为动脉粥样硬化,其中脑动脉硬化62例,颈动脉硬化7例;血管狭窄或闭塞:颈动脉70例,椎基底动脉39例,锁骨下动脉42例,大脑前动脉18例,大脑中动脉18例,大脑后动脉24例;45例血管发育变异,33例为动脉瘤,1例为烟雾病,1例动静脉畸形,前后交通动脉开放分别为80例和55例,脑动脉正常者10例,颈动脉正常者34例。西门子双源螺旋CT可清楚显示病变的数目、大小、部位、形状以及与其周围血管和相邻颅骨的主要关系,与数字减影血管造影检查及手术所见结果大体一致。结论双源螺旋CT血管成像在头颈部血管病变中具有极大的临床应用价值,其检查安全性较高、精确性良好,而且有扫描速度快,检查过程短等优点,同时大大降低了辐射剂量和对比剂用量,所得图像能够满足诊断需求,值得临床在头颈部血管病变的筛查、诊断及治疗后随访中首选应用。
Objective To analyze the clinical value of Siemens dual-source spiral CT angiography in the diagnosis of head and neck vascular diseases.Methods A total of 179 patients with highly suspicious head and neck vascular disease from December 2017 to April 2018 were enrolled in our hospital.Double-source spiral CT angiography was performed.The angiography of Siemens dual-source spiral CT was performed using MPR,CPR,MIP and VR,and the imaging results were analyzed.Results 69 cases of atherosclerosis,including 62 cases of cerebral arteriosclerosis,7 cases of carotid atherosclerosis;stenosis or occlusion：70 cases of carotid artery,39 cases of vertebral basilar artery,42 cases of subclavian artery,18 cases of anterior cerebral artery,there were 18 cases of middle cerebral artery and 24 cases of posterior cerebral artery;45 cases of vascular developmental variation,33 cases of aneurysm,1 case of moyamoya disease,1 case of arteriovenous malformation,the anterior and posterior communicating artery arteries were 80 and 55,respectively,10 with normal cerebral arteries and 34 with normal carotid arteries.Siemens dual-source spiral CT can clearly show the number,size,location,shape of the lesions and the main relationship between the surrounding blood vessels and adjacent skulls, and the results of digital subtraction angiography and surgery are generally consistent.Conclusion Dual-source spiral CT angiography has great clinical value in the treatment of head and neck vascular lesions.It has high safety and accuracy, and it has the advantages of fast scanning speed,short inspection process and greatly reduced radiation.The dose and contrast dose,the obtained image can meet the diagnostic needs,it is worthy of clinical application in the screening,diagnosis and post-treatment follow-up of head and neck vascular lesions.
