Abstract: Objective To evaluate the feasibility of the three-dimensional brain artery vessel wall imaging technology reverse rotation angle of fast spin echo (T1 W-SPACE)in the diagnosis of ischemic cerebrovascular disease by comparing it with TOF vascular imaging in magnetic resonance. Methods Patients undergoing stroke but stable condition,including 50,patients with transient cerebral ischemia (TIA)or a history of stroke,examined by TOF-MRA and routine MRI sequence first,then followed by T1 W-SPACE.Results In 43 of 50 cases,conventional MRI sequences detectiog was positive,TOF-MRA found the vascular stenosis in 76 branches,T1 W-SPACE found the vascular stenosis in 73 branches,there was no difference between the two groups(χ2 =0.625,P >0.05);Conventional TOF-MRA cannot detect the vascular wall, T1 W-SPACE found that arterial wall thickening,plaque in 48 branches.Conclusion Compared with the TOF-MRA,T1 W-SPACE can not only detect the vessel stenosis,but also the vessel wall and plaque,and can also type on plaque from pathology angle,has im-portant clinical significance for early prevention and treatment of stroke.
