Abstract:
Objective To analyze the clinical value of 1.5T MRI DWI and SWI sequence in the diagnosis of cerebral infarction and cerebral hemorrhage.Methods A total of 28 patients with cerebral infarction were selected as control group,and 28 patients with cerebral hemorrhage were selected as observation group.The PHILPS 1.5T magnetic resonance imaging system was applied.The patients were examined by T1WI and T2WI sequence scanning,and DWI and SWI sequence images were obtained.In the two groups,lesions around the center and different characteristics of SWI and DWI were observed and compared,and the measurement of peripheral lesions were measured for calculating the central area of the PV and ADC.Results There was no significant difference between T1WI and T2WI in patients with cerebral hemorrhage and cerebral infarction,but there was significant difference between DWI sequence and DWI sequence.MRI routine examination showed that there were no significant differences in detection rates of T1WI sequence and T2WI sequence between two groups,but the detection rate of DWI sequence in the observation group was significantly lower than the control group,while detection rate of DWI sequence was significantly higher than the control group(P<0.05).The central area of ADC in the observation group was significantly better than that in the control group,and the PV value of the hematoma area was significantly lower than that of the control group(P<0.05).Conclusion Collections of DWI and SWI images of cerebral infarction and cerebral hemorrhage by magnetic resonance prove that there are significant differences between characteristics of two images.
