The Screening Value of Magnetic Resonance 3D-ASL Perfusion Technology for Acute Ischemic Stroke
Objective This study combines magnetic resonance multimodal imaging technology to explore the screening value of 3D-ASL perfusion technology for acute ischemic stroke.Methods To prospectively analyze the imaging data of 55 patients with unilateral lesions who were examined by the Stroke Channel in the Magnetic Resonance Department of the First Affiliated Hospital of Henan University of Chinese Medicine from October 2019 to November 2022,evaluate and measure DSC-PWI and 3D-ASL imaging methods,and compare the consistency of the two methods in screening acute ischemic stroke;Compare the differences in cerebral blood flow(CBF)between 3D-ASL groups;Count the occurrence of vascular high signal(FVH sign)and arterial transit artifacts(ATA sign),and summarize the patterns of their occurrence.Results Using DSC-PWI as the gold standard,3D-ASL exhibits considerable diagnostic efficacy in evaluating the core infarct area,blood flow perfusion,and ischemic penumbra in AIS patients;The CBF values of the infarct core area,IP area,and contralateral mirror area measured by 3D-ASL showed significant statistical differences(P＜0.05);The appearance of FVH and ATA signs in the affected IP area brain tissue showed high consistency(=10.154,P＞0.05).Conclusion 3D-ASL technology can accurately evaluate the qualitative and quantitative images of AIS patients,with multiple advantages and high diagnostic value,providing a reliable imaging basis for clinical diagnosis and treatment.
