The perivenular relationship of MS demyelinating plaque is thought to represent one of the most histologically specific features of MS. In this retrospective study, the authors directly compared the utility of 3T SWI, 7T SWI, and T2&WI in detecting central vein sign (CVS) and the ability of CVS to differentiate MS from nonspecific WM lesions in patients without MS (presumed vascular origin) in a large cohort of patients. They found that 7T SWI and T2* (73% and 87% of lesions, respectively) showed significantly more CVSs than 3T (31%). Both T2*WI and 7T SWI sequences were 100% accurate (AUC=1.0) for diagnosing MS from WM lesions of presumed vascular origin, which was superior to 3T (AUC=0.975).

This retrospective multi-institution cohort study analyzed the temporal features of CSF-venous fistula (CVF) visualization on dynamic decubitus CT myelography (dCTM) in 48 patients. The results showed that most CVFs were visible on first or subsequent phases of dCTM, but approximately 1 in 8 were only visible on either the early or delayed phase. The authors conclude that acquiring greater than 1 phase of imaging increases the sensitivity of dCTM by increasing its temporal resolution.

This systematic review and meta-analysis aimed to compare the diagnostic test accuracy for CTA and CTP in the detection of distal medium vessel occlusion. The study found consistent evidence for a higher sensitivity in detecting distal medium vessel occlusion, particularly in arteries beyond the M2 segment of MCA, with multiphase CTA or CTP compared with single-phase CTA.
