Introduction For acute ischemic stroke (AIS) patients, collateral flow helps to maintain the blood supply to the brain region when the main artery supplying the region is occluded (1). Collateral flow after cerebral occlusion plays an important role in preventing ischemic tissue from progressing to infarction and can be a marker of the ischemic penumbra (salvageable brain tissue) (2).

Neuroradiologists provide quality-assured neuroimaging ­reports. We developed the use of a neuroimaging team meeting to provide second-opinion reporting by neuroradiologists on neuroimaging that had previously been reported by general ­radiologists. Neuroimaging from selected patients was reviewed at the meeting.
