Venkatasamy A, Huynh TT, Wohlhuter N, et al. - Since vestibular neuritis is the second cause of vertigo and new imaging protocols are proposed for diagnosis using delayed FLAIR with double-dose of gadolinium, researchers desired to know whether a single dose of gadolinium is sufficient. For this investigation, they compared 33 patients with unilateral vestibular neuritis to a control group. All study participants had a FLAIR sequence, 1 hour after intravenous injection of a single dose of gadolinium, on a 1.5 Tesla MRI. Using Bayesian analysis, the statistics were performed. The data presented in this work showed a strong enhancement of the superior vestibular nerve (sup VN) on the pathological side in 85% of patients with vestibular neuritis. Investigators found that the pathological sup VN's average signal intensity was more than twice the control group's average intensity. Findings revealed that a delayed FLAIR sequence, obtained 1 hour after a single dose of gadolinium injection, is a helpful method for vestibular neuritis diagnosis. In favor of diagnosis was an enhancement of the sup VN > 71.5 units.
