Introduction. Neurobehavioral deficits are common after cardiopulmonary bypass, but magnetic resonance imaging (MRI) seldom reveals significant abnormalities. We would be better able to evaluate new neuroprotective interventions if a sensitive quantifiable measure of acute brain injury were available. Diffusion weighted imaging (DWI) is purported to be sensitive to acute brain injury, and several clinical trials are under way using DWI to determine if off-pump coronary artery bypass grafting causes less brain injury than traditional on-pump procedures. In an effort to empirically determine . . . [Full Text of this Article]
