摘 要: | 目的探讨多层螺旋CT血管成像技术诊断头颈部血管狭窄性的临床意义。方法随机抽取临床怀疑发生头颈部血管狭窄性病变而行头颈部CTA检查的我院患者50例为研究对象,采用多层螺旋CT减影去骨血管成像技术后处理,判断血管是否狭窄,并对狭窄程度进行评估。结果本研究最终共检测644段血管,发现狭窄146段(检出率为22.67%):轻度狭窄48段、中度狭窄47段、重度狭窄42段、闭塞9段,分别占32.88%、32.19%、28.78%、6.16%。颈部各类型血管之间的各狭窄程度的检出率据有统计学差异(X2=23.435,P=0.001);头部各类型血管之间的各狭窄程度的检出率据无统计学差异(X2=11.159,P=0.265)。结论CT血管减影成像可早期发现和诊断颈部动脉狭窄性病变,并对血管的狭窄程度等作出客观评估与判断,为临床及时治疗提供可靠的影像学资料。

Abstract: | Objective To investigate the clinical significance of multi-slice spiral CT subtraction angiography boneless vascular imaging technology in the diagnosis of head and neck vascular stenosis. Methods 50 patients suspected with lesions of the head and neck vascular stenosis and received head and neck CTA examination were selected in the study and multi-slice spiral CT angiography was used for redevelopment by a variety of reconstruction methods to determine whether vascular stenosis, and to assess the degree of stenosis, results 644 arteries were detected eventually and 146 were found to be narrow (22.67%): nfild stenosis 4g, moderate stenosis 47, severe stenosis 42, paragraph 9 occlusion, accounting for 32.88%, 32.19%, 28.78%, 6.16%. There was a statistically significant difference (X2=23.435, P=0.001) between the various types of vascular stenosis, according to.Conclusions CT subtraction angiography imaging allows early detection and diagnosis of carotid artery stenosis lesions and vascular stenosis and can make an objective assessment of the degree and judgment, which provide reliable clinical imaging data for timely treatment. |
