目的:分析应用多序列联合的检查方式对超早期脑梗死患者的临床诊断意义。方法:对应用多序列磁共振检查(包括T1W成像、T2W成像、DW成像、FLAIR成像及MRA成像)的超早期脑梗死患者共30例进行回顾性分析,分析成像对超早期脑梗死患者检出的敏感性及MRA分级与梗死面积的关系。结果:DW检出率明显高于其他3种成像的检出率(P<0.05),而T1W成像、T2W成像及FLAIR成像检出率比较差异无统计学意义(P>0.05)。MRA动脉显像分级与梗死面积呈正向直线相关,MRA动脉显像分级越高,出现大面积脑梗死越多。结论:多序列联合的检查对超早期脑梗死患者的检出率高,且可对梗死面积进行初步的预测。
OBJECTIVE: To analyze the clinical diagnostic value of multi-sequence combined examination in patients with ultra-early cerebral infarction. Methods: A total of 30 patients with ultra-early cerebral infarction who underwent multi-sequence magnetic resonance imaging (including T1W imaging, T2W imaging, DW imaging, FLAIR imaging and MRA imaging) were retrospectively analyzed. Imaging analysis was performed on patients with ultra-early cerebral infarction Sensitivity and the relationship between MRA classification and infarct size. Results: The detection rate of DW was significantly higher than that of the other three kinds of imaging (P <0.05). There was no significant difference between T1W imaging, T2W imaging and FLAIR imaging (P> 0.05). MRA arterial imaging grading and infarction area was a positive linear correlation, MRA arterial imaging grading higher, more large area cerebral infarction. CONCLUSIONS: The detection of multiple sequences combined with high early detection of cerebral infarction patients, and preliminary prediction of infarct size.
