High-resolution MRI combined arterial spin labeling may distinguish between transient ischemic attack and stroke in intracranial stenosis

In order to prevent TIA patients from further developing into irreversible stroke, it is important to predict the occurrence of stroke in TIA patients. In this study, high-resolution magnetic resonance imaging (HRMRI) and arterial spin labeling (ASL) were used to investigate the differences of middle cerebral artery (MCA) plaque and hemodynamics in patients with ischemic stroke and TIA, and to establish a predictive model for ischemic stroke. The results showed that positive remodeling, enhancement ratio and 2.5s ATA present could be used to predict the occurrence of stroke in patients with TIA, and the prediction model had excellent diagnostic performance.
