Latest issue of Radiology-Cerebral Circulation Time in MS

Study by Marcello Mancini, MD et al  in Radiology, 262, 947-955 suggest that contrast-enhanced US with CCT assessment may have a role in the evaluation of cerebral blood flow in patients with MS and that a vascular impairment could be associated with MS. The finding of a prolonged CCT at contrast-enhanced US does not result from outflow impairment. Further studies are required to verify these observations and to clarify if CCT and CCSVI have any physiologic and clinical relevance in MS.
