This
study aims at implementation and evaluation of vessel size imaging (VSI) in
patients with ischemic stroke. Stable values of vessel diameter have been
observed in healthy volunteers in a good agreement with anatomic knowledge.
VSI measurement is shown to be feasible for the clinical examination in
stroke patients. Given the limitations of small number of patients,
hypointensities on VSI maps in acute and chronic stage have been observed in
areas of the final infarction. The recovered tissue showed normal VSI in the
acute phase.
