目的:分析在急性脑梗死诊断中,采用磁共振弥散加权成像(MR-DWI)对疾病检出率提升的价值.方法:回顾性分析2020年1月~2022年9月于本院行常规磁共振成像(MRI)检查的疑似急性脑梗死患者42例纳入对照组;选取同时段在本院行MR-DWI检查的疑似为急性脑梗死的患者42例纳入观察组.以数字减影血管造影检查结果为金标准,比较两组诊断结果、诊断效能及患侧与健侧脑组织表观弥散系数值水平.结果:最终金标准结果显示,对照组患者共确诊阳性31例,阴性11例;观察组患者共确诊阳性31例,阴性11例.观察组诊断效能中的灵敏度、特异度及准确率水平均显著高于对照组(P<0.05).在MR-DWI检查方式下,不同b值时,急性脑梗死患者患侧脑组织表观弥散系数值均较健侧脑组织低(P<0.05).结论:采用联影uMR588 1.5T MRI中的DWI模式检查,对急性脑梗死的诊断灵敏度、特异度及准确率均处于较高水平,临床诊断价值较高.
Clinical Value of Magnetic Resonance DWI in the Diagnosis of Acute Cerebral Infarction
Objective:To analyze the value of using diffusion weighted imaging(MR-DWI)in the diagnosis of acute cerebral infarction in improving disease detection rate.Methods:A retrospective analysis was conducted on 42 suspected acute cerebral infarction patients who underwent routine MRI examination in our hospital from January 2021 to September 2022,and they were included in the control group;42 patients suspected of acute cerebral infarction who underwent magnetic resonance MR-DWI examination in our hospital during the same period were selected and included in the study group.Using the results of digital subtraction angiography(DSA)as the gold standard,compare the diagnostic results,diagnostic efficacy,and ADC levels of the affected and healthy brain tissues between the two groups.Results:The final gold standard results showed that a total of 31 patients in the control group were confirmed positive and 11 were negative;A total of 31 patients in the study group were confirmed positive and 11 were negative.The sensitivity,specificity,and accuracy levels in the diagnostic efficacy of the study group were significantly higher than those of the control group(P<0.05).Under the MR-DWI examination method,the ADC value of the affected brain tissue in patients with acute cerebral infarction was lower than that of the healthy brain tissue at different b values(P<0.05).Conclusion:The DWI mode examination in the 1.5T MRI of combined imaging uMR588 has high diagnostic sensitivity,specificity,and accuracy for acute cerebral infarction,and has high clinical diagnostic value.
