Imaging continues to be a mainstay of stroke diagnosis, management, and investigation, and this was fully evident again in 2007. Stroke continues to command a substantial amount of attention from investigators from a wide variety of disciplines. A broad range of insights and innovations in imaging have occurred in the past year, and the space allotted here remains too small to capture the range of efforts. In this survey we will discuss the ongoing advances in optimal imaging of the acute stroke patient, the role of imaging as a biomarker or surrogate end point, as well as efforts to use imaging to assess the risk of hemorrhage after chemical thrombolysis. Important data about the frequency of incidental stroke have been published. And, in a special focus, we will describe the role imaging has played this past year in building understanding of recovery from stroke.

One ongoing area of investigation regards the manner in which to optimally image the acute stroke patient. Guidelines issued this year¹ provide an excellent summary: x-ray computed tomography (CT) guides most treatment decisions, and therapy should not be delayed to obtain multimodal imaging studies. However, multimodal imaging with CT and with MRI may provide additional information that will improve the diagnosis of acute ischemic stroke. Indeed, recent data suggest that CT angiography and perfusion assessment with CT is both feasible and in the specific setting of hemispheric stroke can provide assessment of vessel status such as site of occlusion, tissue damaged and potentially at risk, and . . .
