Abstract
Neuroendovascular therapy has been widely induced in the treatment of the cerebrovascular disease for the last several decades. Cerebral vessels, targets of the neuroendovascular therapy, have two aspects; the one is a pipe supplying the blood flow to the brain, and the other is a tissue growing, remodeling, and regressing itself. Thus, the assessment of neuroendovascular therapy should not only be done with an angiographic point of view, but also with changes of the blood flow and metabolism in cerebral or targeting tissue. Here, the author discusses the present and the future research of the cerebral blood flow and metabolism in the field of the neuroendovascular management.
