摘要
目的 研究将磁共振成像(MRI)、电子计算机断层扫描(CT)应用于缺血性脑卒中患者中的作用与效果。方法 2019年4月—2020年12月濮阳市油田总医院接收并对其进行诊断的缺血性脑卒中患者18例,对其进行MRI检测[其中,包括Bravo T1加权成像(T1WI)、T2加权成像(T2WI)、扩散加权成像(DWI)、液体衰减反转恢复序列(FLAIR)、高分辨CUBE T1WI、三维时间飞跃法磁共振血管成像(3D-TOF-MRA)、CT血管成像(CTA)、多延迟伪连续动脉自旋标记(pCASL)、CT灌注(CTP)],鉴于CUBE T1WI、3D-TOF-MRA、CTA,判断患者是否存在责任血管,并对其管腔狭窄程度进行评估,应用多延迟pCASL灌注,得到患者的脑血流量(CBF)、动脉通过时间(ATT),应用CT灌注获取患者的CBF、平均通过时间(MTT),比较最终的结果。结果 应用CUBE T1WI、3D-TOF-MRA、CTA,提示共16例患者出现脑动脉狭窄,两两间对比狭窄程度差异有统计学意义(P<0.05);鉴于体素水平,提示磁共振动脉自旋标记技术(ASL)-CBF、CTP-CBF处于白质、灰质、全脑体现出中强度正向的关系,P<0.05,ASL-ATT、CTP-MTT处于白质、灰质、全脑体现出明显正向的关系,P<0.05。结论 缺血性脑卒中患者的诊断中,应用3D-TOF-MRA、高分辨CUBE T1WI、CTA,能够尽早发现患者的病变血管,以评估患者是否存在责任血管并对其处理;CUBE T1WI可以由多个平面对动脉狭窄、血管壁形态进行评估;多延迟pCASL灌注十分安全,且具有无创性。
Objective To study the effects of magnetic resonance imaging(MRI) and computer tomography(CT) in patients with ischemic stroke.Methods A total of 18 patients with ischemic stroke admitted and diagnosed in our hospital from April 2019 to December 2020 were selected for MRI detection [among them, Including Bravo T1-weighted imaging(T1WI), T2-weighted imaging(T2WI), diffusion-weighted imaging(DWI), liquid attenuated inversion recovery sequence(FLAIR) and high-resolution CUBE T1WI, 3D time-leap magnetic resonance angiography(3D-TOF-MRA), CT angiography(CTA), multi-delay pseudo-continuous arterial spin labeling(pCASL), CT perfusion(CTP)], and in view of CUBE T1WI, 3D-TOF-MRA, AND CTA, the presence of responsible vessels can be determined. The degree of lumen stenosis was evaluated, cerebral blood flow(CBF) and arterial passage time(ATT) were obtained by multi-delay pCASL perfusion, and CBF and mean passage time(MTT) were obtained by CT perfusion, and the final results were compared.Results Using CUBE T1WI, 3D-TOF-MRA and CTA, a total of 16 patients showed cerebral artery stenosis, and the degree of stenosis was different in pairs(P<0.05). In view of the voxel level, it was suggested that magnetic resonance arterial spin labeling technology(ASL)-CBF and CTP-CBF were positively correlated with the intensity of white matter, gray matter and whole brain, P<0.05, while ASL-ATT and CTP-MTT were significantly positively correlated with the intensity of white matter, gray matter and whole brain, P<0.05.Conclusion In the diagnosis of ischemic stroke patients, the application of 3D-TOF-MRA, high-resolution CUBE T1WI and CTA can detect the diseased blood vessels of patients as early as possible, so as to evaluate the presence of responsible blood vessels and manage them. CUBE T1WI can be used to evaluate arterial stenosis and vascular wall morphology by multiple planes. Multidelay pCASL perfusion is safe and noninvasive.
