This study aimed to investigate the application value of DWI combined with ASL and MRA in the evaluation of ischemic penumbra in cerebral infarction. A prospective study was conducted on 60 patients with diagnosed cerebral infarction and ischemic penumbra, and DWI, ASL, and MRA were performed for image analysis. The results showed that the combined use of DWI, ASL, and MRA can effectively evaluate the severity of the disease, lesion range, and vascular state in patients with ischemic penumbra. Among them, DWI can accurately diagnose cerebral infarction, ASL can detect perfusion abnormalities, and MRA can display vascular states and blood flow dynamics. Therefore, the comprehensive application of DWI combined with ASL and MRA can provide clinicians with comprehensive and accurate diagnosis and treatment decision support for cerebral infarction with ischemic penumbra, and improve the treatment effect and quality of life of patients.Keywords: ischemic penumbra;...
