Transient ischemic attack (TIA) is defined as focal neurological deficit caused by ischemia resolving within 24 hrs. In a secondary analysis of a large monocentric cohort of 446 TIA patients, we explored the frequency and determinants of DWI lesions on high-resolution MRI. Overall, 240 (54%) of all TIA patients presented with DWI lesions. These patients had higher NIHSS and ABCD2 scores and presented more frequently with vessel occlusion and perfusion deficits, but had similar functional outcome at 3 months. Taken together high-resolution DWI provides evidence of ischemic brain injury in the majority of TIA patients. This article is protected by copyright. All rights reserved.
