Summary

Magnetic resonance imaging (MRI) is the diagnostic cornerstone for precisely identifying acute ischaemic strokes and locating vascular occlusions. It was observed that a post-contrast three-dimensional turbo-spin-echo T1weighted sequence showed striking post-contrast vascular hyperintensities (PCVH) in ischaemic territories. The aim is to evaluate the prevalence and the meaning of this finding. This study included 130 consecutive patients admitted for acute ischaemic stroke with a 3-T MRI performed in the first 12 h of symptom onset from September 2014 through September 2016. Two neuroradiologists blinded to clinical data analysed the first MRI assessments.
