[Brain imaging patterns after stroke].
The advent of new imaging techniques, such as diffusion-weighted sequences, has a great impact on the diagnostic imaging in stroke. The aim of the present paper is to review the brain imaging patterns after stroke, highlight the usefulness of imaging technique for the diagnosis and etiological work-up after stroke. Three causes of ischemic stroke (cerebral venous thrombosis, aortic arch atheroma, patent foramen ovale) are detailed.
