Purpose : The purpose of this study was to evaluate the possibility of utilizing magnetic resonanceangiography(MRA) in patients with cerebral infarction by comparative analysis of magnetic resonance imaging(MRI).Materials and Methods : MRI and MRA using 3D time-of-flight(TOF) technique with magnetization transfer andramp(MTR) or 3D TOF with multiple overlapping thin slab acquisition(MOTSA) were performed in 39 patients withcerebral infarction. Vascular lesions detected on MRA were classified as “normal”, “stenosis” and“occlusion”, and the different infarction sites were named according to their vascular territory. Correlationbetween MRI and MRA findings was evaluated. Results : In 24(62%) of 39 cases, MRA showed stenosis or occlusion and19(86%) of those corresponded to their vascular territory of infarction, as visualized on MRI. In 15(62.5%) of the24 cases, MRA revealed additional diagnostic information such as visualization of unpredicted vascular lesions orthe presence of collateral circulations. Of the 15 cases diagnosed as normal according to MRA, most of themactually had small infarctions of less than 2cm in maximal dimension in the area of the perforating arteries.Conclusion : There was a strong correlation between the vascular lesion observed by MRA and the distribution ofthe infarct areas on MRI. Additional information was provided by MRA obtained together with conventional MRI.
