PDFAbstract
Objective To observe the clinical application of magnetic resonance arterial spin labeling (3D-ASL) and diffusion weighted imaging (DWI) in patients with acute cerebral ischemic stroke (CIS). Methods A total of 60 cases of CIS patients in our hospital from January 2017 to February 2018 were selected, and 30 healthy volunteers were enrolled as control group, and all of them were given 3D-ASL and DWI imaging scans respectively. The application value of the two methods in CIS patients was compared. Results In 34 patients with acute ischemic stroke on the right side, the absolute value of right cerebral blood flow (CBF) was significantly lower than that of the left side, and the absolute values of CBF on both sides were lower than those in healthy control group (P<0.05). In 26 patients with acute ischemic stroke on the left side, the absolute values of bilateral cerebral blood flow (CBF) were lower than those in healthy control group (P<0.05). Conclusion 3D-ASL can clearly show the hemodynamic changes of ischemic infarct lesions in patients with CIS, and combined with CBF value was more objective in responding to the ischemic infarction perfusion of brain tissue, and can provide an important basis for the clinical diagnosis of CIS.
