CE-MRA and TOF-MRA do not differ regarding the evaluation of normal intracranial vessels. CE-MRA provides the advantage of good visualization of vessels distal to occluded segments. Furthermore CE-MRA allows visualization of extracranial vessels and faster image acquisition. TOF-MRA can be equivalently used if the administration of contrast agents is not possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
