Two-year progress reports from the seven MS Society-funded CCSVI studies on MS

As of July 2012, most of the seven research projects investigators are in the process of completing their work and expect to do so within the next year. The research teams have recruited and scanned a broad spectrum of people with MS and others to build understanding of who may be affected by CCSVI (chronic cerebrospinal venous insufficiency). In addition they are refining CCSVI imaging methods for accuracy and consistency to reliably validate the occurrence of CCSVI and understand its implications in the MS disease process. Already more than 900 people have undergone scanning with various imaging technologies being used by the studies, including the Doppler ultrasound technology used by Dr. Paolo Zamboni and his collaborators, as well as magnetic resonance studies of the veins (MR venography), catheter venography, MRI scans of the brain, and clinical measures. Even though the work continues for several of the teams, some are already presenting preliminary results at medical meetings, and all have shared technical advice so that the projects can move forward as smoothly and quickly as possible. Updates will continue as appropriate to reflect the ongoing transparency of the work being supported by the U.S and Canadian MS Societies.
