Diagnostic performance of central vein sign and paramagnetic rim lesion integration for multiple sclerosis.
The central vein sign (CVS) and the paramagnetic rim lesion (PRL) are neuroimaging biomarkers of multiple sclerosis (MS).
To determine the diagnostic performance of CVS and PRL integration in people presenting for initial diagnostic evaluation of MS.
Adults with clinical/radiological suspicion of MS, aged 18-65, with CVS and PRL assessment from the CentrAl Vein Sign in MS (CAVS-MS) pilot were included. Diagnostic performance of CVS and PRL combinations was evaluated, with 2017 McDonald criteria as the reference standard.
Seventy-eight participants were included (71% female, 86% white, 37 with MS). The combination of ⩾1 CVS and ⩾1 PRL demonstrated sensitivity/specificity of 0.76 (95% CI, 0.59, 0.88) and 0.93 (95% CI, 0.80, 0.98). The combination of ⩾6 CVS and ⩾1 PRL demonstrated sensitivity/specificity of 0.57 (95% CI, 0.39, 0.73) and 1.00 (95% CI, 0.91, 1.00). In those with cerebrospinal fluid testing (n = 46, 24 with MS), ⩾6 CVS and ⩾1 PRL diagnostic specificity was 1.00 (95% CI, 0.85, 1.00), similar to that of oligoclonal bands and dissemination in space by magnetic resonance imaging (0.82 [95% CI, 0.60, 0.95]).
Integrating CVS and PRL represents potentially advantageous MS diagnostic biomarkers, with increased specificity and without substantial reduction in sensitivity.
