The comparison of MR images and cadaver microangiograms of the basal perforating arteries is crucial for understanding the courses and supply areas of these vessels and in turn, for diagnosing pathologies in this region. Divided into three sections- normal anatomy of brain vessels; neurovascular imaging in pathology; and anatomy and imaging of spinal vessels- Neurovascular Imaging contains a rich collection of images to teach the reader how to interpret MR images of the brain vessels and spinal vessels, and how to identify pathological signs. Written and edited by a group of highly acclaimed experts in the field, Neurovascular Imaging is an authoritative account of the interpretation of MR images of the brain vessels and spinal vessels, and is a valuable addition to the library of the diagnostic radiologist.
