What is the impact of multimodal MRI on patient outcomes in stroke patients?
A systematic review in 2012 found no evidence that multimodal MRI when used purely for diagnostic purposes improves outcomes, although there was limited evidence that it can change management. The use of MRI for in-hospital stroke evaluation grew dramatically from 1999 to 2008, varying widely. The growth was likely related to widespread appreciation of the diagnostic yield of follow-up brain imaging with MRI within 1 to 2 days.
