急性期缺血性脑梗塞患者CT与MRI检查结果比较分析

Compare the Tested Results for the Patients with Acute Phase of Ischemic Cerebral Infarction by Computed Tomography and Magnetic Resonance Imaging

目的探讨急性期缺血性脑梗塞患者CT与MRI检查结果。方法对患者进行CT扫描和MRI扫描。观察患者检出病例数目、大小、时间、病灶直径大小、病理部位、征象。结果 60例患者中,CT不能够检出发病6h内的AICI,MRI检出21例;6-24h内CT检出2例,MRI检出35例,两种方法比较,差异有统计学意义(P<0.05),1-3d CT检出19例,MRI检出20例,两种方法比较,差异无统计学意义(P>0.05)。60例患者中,随着病情的进展,MRI和CT图像显示的病灶数量显著增加,但MRI检出病灶数量显著高于CT,差异有统计学意义(P<0.05)。MRI和CT对病灶的检出能力有统计学意义(P<0.05)。CT征象包括脑实质密度减低、灰白质界面模糊、脑沟裂和脑池变浅、消失等。MRI征象包括DW1序列高信号和FLAIR序列动脉线样高信号。结论采取MRI对急性期缺血性脑梗塞患者进行检测,其诊断效果比CT好,在发现病症、病灶数量、病灶的检出能力方面,效果较好,临床应用价值较高。

Objective To explore the tested results for the patients with acute phase of ischemic cerebral infarction by computed tomography and magnetic resonance imaging. Methods CT scan and MRI scans on the patients.Observe patients detected cases number. size, time, lesion diameter size, pathological parts and signs. Results 60 cases, CT will not be able to check disease within 6 h AICI, MP.I detected 21 cases, Within 6 to 24 h CT detection in 2 cases, MP.I detected in 35 cases, two methods of comparison, the difference was statistically significant （P〈0.05）, 1-3 DCT detected 19 cases. MRI detected 20 cases, two methods of comparison, there was no statistically significant difference （P〉0.05）. 60 cases of patients, with the progress of the disease, MRI and CT images show a dramatic increase in the nulnber of lesions, but there is significantly higher than CT, MRI detected lesions to tile difference was statistically significant （P〈0,05）. MRI and CT of lesion detection ability was statistically significant （P〈0.05）. CT signs include parenchymal density reducing groove, fuzzy and grey matter interface crack and brain pool becomes shallow, disappear, etc.MRI signs include DW1 sequence high signals, and high FLAIR sequence arterial line samples. Conclusion It has good diagnosis for the patients with acute phase of ischemic cerebral infarction by magnetic resonance imaging, find the condition at the, number of lesions, lesion detection ability, the effect is better, it has high values on clinical application.
