• Sommario/riassunto: he first book-length reference to thoroughly describe diagnostic and therapeutic advances in the development of vascular radiology over the last decade The last ten years has seen vascular imaging of the central nervous system (CNS) evolve from fairly crude, invasive procedures to more advanced imaging methods that are safer, faster, and more precise-with computed tomographic (CT) and magnetic resonance (MR) imaging methods playing a special role in these advances. Vascular Imaging of the Central Nervous System is the first full-length reference text that shows radiologis
