CT血管造影与磁共振诊断颈内动脉颅内段血管狭窄的价值(1)
【摘要】 目的:观察CT血管造影与磁共振诊断颈内动脉颅内段血管狭窄的价值,对于临床科学有效的诊断颈内动脉颅内段血管狭窄疾病做出重要的指导,提供给患者最佳的治疗时机。方法:本次研究对象为于笔者所在医院实施治疗的82例颈内动脉短暂性脑缺血发作或缺血性脑卒中患者,所有患者均进行CT血管造影、磁共振和数字减影血管造影检测,将数字减影血管造影的检查结果作为金标准,对CT血管造影和磁共振诊斷准确率进行分析。结果:82例患者涉及到380段,C1~C3段、C4段、C5段分别是132段、126段及122段。相较于磁共振,实施CT血管造影诊断C4段及C5段的准确率更高,差异有统计学意义(P<0.05)。CT血管造影诊断敏感度及特异性分别为89.25%(181/194)、93.30%(166/186),磁共振诊断敏感度及特异性分别为87.63%(170/194)、80.65%(150/186),两组比较差异有统计学意义(P<0.05)。结论:对颈内动脉颅内段血管狭窄患者展开诊断期间,落实CT血管造影与磁共振诊断时应用CT血管造影诊断效果更好,准确率更高。

[Abstract] Objective: To observe the value of CT angiography and MRI in the diagnosis of intracranial stenosis of internal carotid artery, and to provide important guidance for the clinical scientific and effective diagnosis of intracranial stenosis of internal carotid artery, and to provide the patients with the best opportunity for treatment. Method: The subjects of this study were 82 patients with transient ischemic attack or ischaemic stroke who were treated in our hospital. All the patients were examined by CT angiography, MRI and DSA. The results of DSA were used as the gold standard. The accuracy of CT angiography and MRI was analyzed. Result: A total of 82 patients involved 380 segments, C1-C3 segment, C4 segment and C5 segment were 132 segment, 126 segment and 122 segment respectively. Compared with MRI, the accuracy of CT angiography in the diagnosis of C4 and C5 segments was higher, the difference was statistically significant (P<0.05). The sensitivity and specificity of CT angiography were 89.25% (181/194) and 93.30% (166/186), respectively. The sensitivity and specificity of MRI were 87.63% (170/194) and 80.65% (150/186), respectively, the difference between the two groups was statistically significant (P<0.05). Conclusion: During the diagnosis of intracranial stenosis of internal carotid artery, CT angiography is more effective and accurate in the implementation of CT angiography and MRI.
颈内动脉狭窄属于缺血性脑血管病的独立性危险因素,这是临床研究普遍认可的一项结果,同时根据相关的数据调查显示,有50%以上的脑卒中患者产生于颈内动脉供血区。进行颈内动脉颅内段血管狭窄诊断的方式较多,其中较常应用的就是CT血管造影及磁共振等方式,诊断颈内动脉颅内段血管狭窄中,数字减影血管造影处在“金标准”位置上[1-3]。为了分析诊断颈内动脉颅内段血管狭窄的最优成效,此次研究选取82例颈内动脉短暂性脑缺血发作或缺血性脑卒中患者作为研究对象,进行CT血管造影与磁共振诊断的模式,观察两种影像技术的诊断精准度,提供给临床诊断工作有价值的指导,现报告如下。
1 资料与方法
1.1 一般资料
此次研究对象均为笔者所在医院进行治疗的82例拟诊为颈内动脉短暂性脑缺血发作或缺血性脑卒中患者,选取时间为2017年1月-2019年5月。患者具有颈内动脉供血区功能障碍情况,存在偏盲、失语或者偏瘫等临床症状,82例患者中,男42例,女40例;年龄最大84岁,年龄最小40岁,平均(60.2±1.6)岁。患者对此研究具备知情权,并签署知情同意书。
1.2 方法
82例患者都实施相同的检查方案,即CT血管造影、磁共振、数字减影血管造影检查。首先,CT血管造影方法为:实施飞利浦西门子SOMATOM Definition AS 64排螺旋CT机仪器设备,定位扫描头颈部位,以Medrad CT型双筒,高压静脉注射非离子对比剂碘伏醇60~80 ml,按照4.0~4.5 ml/s的速率。之后严格的扫描主动脉弓下缘到颅顶的位置,设置电压120 kV。然后在EBW4.5工作站传送图像,实施图像后处理操作;其次,磁共振检查方法为:实施西门子1.5T Avanto 扫描机,以头部正交线圈实施横断面扫描,然后落实血管成像检查操作;另外,数字减影血管造影检查方法为:实施仪器为西门子 Artiszee IZZ血管造影机,采取碘伏醇320为对比剂,如果观察到血管病变,尽快地调整好方位、角度,得到相应血管病变方位图像。, http://www.100md.com(徐敬轩 杨岩 张勖 买买提依里江·木合塔尔 栾新平)
