These are rather interesting MRI images sent to me by a friend Philip Chao, his website www.3t-mri.net . Dr Philip W Chao has worked in Delaware to produce the best MRIs possible since 1990. He has monitored hundreds of thousands of MRIs over his career at the University of Pennsylvania and working for the people of Delaware. He is a board certified neuroradiologist and recently passed his maintenance of certification examination in 2006. He is also trained in body MRI and was the body MRI fellow at the University of Pensylvania from 1988 through 1990.
These images show a rather unusual bullseye in the proximal right IJ vein, which could represent recanalized old thrombosis. Patient had MRI brain findings which may possibly indicate MS. And it is a image which makes one think about the coincidence of venous outflow obstruction and MS.

According to this paper-CDMS is strongly associated with CCSVI, a scenario that has not previously been described, characterised by abnormal venous haemodynamics determined by extracranial multiple venous strictures of unknown origin. The location of venous obstructions plays a key role in determining the clinical course of the disease.
