磁共振成像技术在急性缺血性脑卒中患者中的应用效果分析

Effect Analysis of Magnetic Resonance Imaging in Patients with Acute Ischemic Stroke

目的对比分析磁共振成像技术在急性缺血性脑卒中患者中的应用效果。方法选择2017年4月至2018年5月时间段内我院收治的急性缺血性脑卒中患者63例为研究样本,其中,预后良好患者26例、预后一般患者20例、预后较差患者17例。对所有患者均进行磁共振成像技术扫描,比较所有患者病灶范围内的容积比各向异性、平均扩散系数、衰减指数和部分各向异性等指标值与对侧检测值之间的差异。结果磁共振成像技术影像结果表示,三组患者在病灶范围内所采集到的容积比各向异性、平均扩散系数和部分各向异性检测值,相较于对侧指标值而言,均较低,差异显著,具有统计学意义(P<0.05)。而在衰减指数方面,三组患者的检测值显著高于对侧数据,差异具有统计学意义(P<0.05)。同时,病灶范围内的部分各向异性和容积比各向异性的检测值随着预后效果的变化而变化,预后效果逐渐变差,患者的检测值也呈现逐渐降低的趋势。预后良好患者的部分各向异性和容积比各向异性检测值显著高于预后较差的患者,差异具有统计学意义(P<0.05)。结论对急性缺血性脑卒中患者实施磁共振成像技术扫描,其成像的影像学结果可清晰显示患者的病灶特点,可为医师鉴别疾病和制定治疗方案提供有力参考依据,值得临床上应用和推广。

Objective To compare the application of magnetic resonance imaging in patients with acute ischemic stroke.Methods 63 patients with acute ischemic stroke from April 2017 to May 2018 were selected as the study samples,including 26 patients with good prognosis,20 patients with average prognosis and 17 patients with poor prognosis.Magnetic resonance imaging(MRI)scans were performed on all patients to compare the differences between the volumetric Anisotropy,mean diffusion coefficient,attenuation index and partial Anisotropy in all patients.Results MRI imaging showed that the volumetric ratio,mean diffusion coeffi cient and partial Anisotropy measured in three groups of patients within the scope of the lesion were all lower than the opposite side index values,and the difference was signifi cant.Statistical signifi cance(P<0.05).In terms of attenuation index,the detection value of the three groups of patients was signifi cantly higher than that of the opposite side data,and the difference was statistically signifi cant(P<0.05).At the same time,some Anisotropy and volumetric Anisotropy within the scope of the lesion vary with the prognosis effect,the prognosis effect gradually deteriorates,and the patient's detection value also shows a decreasing trend.Some Anisotropy and volumetric Anisotropy of patients with a good prognosis were signifi cantly higher than those with a poor prognosis,and the difference was statistically signifi cant(P<0.05).Conclusion The imaging results of magnetic resonance imaging for acute ischemic stroke patients can clearly show the characteristics of the patients,which can provide a powerful reference for doctors to identify diseases and formulate treatment plans.It is worthy of clinical application and promotion.
