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.
