Abstract
Intralesional venous lumen shrinking detectable by MRI was suggested as an in vivo marker of inflammation in multiple sclerosis MS In our study mean diameters of pre post and intralesional venous sections were determined in 49 patients with MS or clinically isolated syndrome CIS using a pixelwise analysis on susceptibilityweighted fluidattenuated inversion recovery sFLAIR images and T2weighted T2w imaging at 7 Tesla T We observed posttointralesional venous lumen shrinking on T2w images p = 0036 in an analysis of 338 venous sections Pretointralesional venous lumen reduction was only detectable in less than 50 of lesions and failed statistical significance when analysing T2w p = 0325 and sFLAIR images p = 0258 In conclusion thinning of intralesional veins in MS is—if detectable at all—probably less severe than previously reported and affects only a minority of MS lesionsThis work was supported by the German Research Foundation DFG Exc 257 We like to thank Alexander Brandt for statistical support and our technicians and study nurses Antje Els Susan Pikol Cynthia Kraut and Gritt Stoffels for technical support and other assistance This work was supported by the German Research Foundation DFG Exc 257 and by a restricted research grant from TEVA Pharma GermanyKM has nothing to disclose JK has nothing to disclose JD receives research grants from Novartis and Bayer and has received travel support from Novartis and Bayer Honoraria for consultancy from Bayer Genzyme and Teva and speaker honoraria from Bayer Teva Genzyme and Novartis CFP has received travel grants from Teva LH has received speaker honoraria from Biogen Idec Bayer Novartis and MerckSerono He serves on the advisory board for Biogen Idec Novartis Genzyme and TEVA and has received travel support from TEVA MerckSerono and Biogen Idec KR received research support from Novartis as well as speaking fees and travel grants from Bayer Healthcare Biogen Idec Merck Serono Sanofi/Genzyme Teva and Novartis and is supported by the German ministry of education and research BMBF/KKNMS Competence Network Multiple Sclerosis TN is founder of MRITOOLS GmbH Berlin Germany and received speaker honoraria from Siemens Healthcare Erlangen Germany FP has received speaker honoraria travel grants and research grants from Teva/Sanofi Bayer MerckSerono Biogen Idec and Novartis FP is supported by the German Research Foundation Exc 257 and by the German ministry of science BMBF/KKNMS and has received travel reimbursement from the Guthy Jackson Charitable Foundation TS received a travel grant from Bayer Genzyme—a Sanofi company and Novartis JW served for Novartis and BiogenIdec advisory boards received a Novartis research grant and speaker honoraria from Bayer Novartis and BiogenIdec He is supported by the German ministry of science BMBF/KKNMS On behalf of all authors the corresponding author states that there is no conflict of interest
