MRI用于脑梗死后出血性转变的临床应用效果分析

Clinical Application of MRI in Hemorrhagic Transformation after Cerebral Infarction

目的探讨分析对脑梗死后出血性转变进行诊断时使用MRI的临床效果。方法对2017年6月-2019年6月56例经过确诊的脑梗死后出血性转变的患者进行回顾性分析,对所有患者均行MRI和CT诊断,分析两种方法对脑梗死后出血性转变的诊断准确率,及对不同分型脑梗死后出血性转变检出率,和对不同部位的检出率。并对脑梗死后出血性转变的CT和MRI表现进行分析。结果 MRI的诊断准确率89.26%比CT高,差异有统计学意义(χ^2=16.102,P<0.05),对不同分型脑梗死后出血性转变检出率比CT高(P<0.05),对不同部位(除脑叶)的检出率比CT高(P<0.05)。结论在对脑梗死后出血性转变进行诊断时使用MRI比CT更加准确,灵敏度高,且MRI对不同分型检出率均较高,对幕下和幕上出血的检出率也较高。对出血的病灶、形态、数目等均有较高的准确率,因此具有临床应用的价值。

Objective To investigate the clinical effect of MRI in the diagnosis of hemorrhagic changes after cerebral infarction. Methods Retrospective analysis was carried out from June 2017 to June 2019. All 56 patients who had been diagnosed with hemorrhagic changes after cerebral infarction were diagnosed with MRI and CT. The diagnostic accuracy of hemorrhagic changes after cerebral infarction was analyzed, and the detection rate of hemorrhagic transition after different types of cerebral infarction, and the detection rate of different parts. The CT and MRI manifestations of hemorrhagic changes after cerebral infarction were analyzed. Results MRI 89.26%was more accurate than CT,and the difference was statistically significant(χ^2=16.102,P<0.05). The detection rate of hemorrhagic transition after different types of cerebral infarction was higher than that of CT(P<0.05), the detection rate of different sites(expect brain lobe)is higher than CT(P<0.05). Conclusion MRI is more accurate and sensitive than CT in the diagnosis of hemorrhagic changes after cerebral infarction, and MRI has higher detection rates for different types, as well as lower curtain and upper curtain hemorrhage. It has high accuracy on the lesion, morphology and number of bleeding, so it has the value of clinical application.
