ED patients with vertigo demonstrate increased prevalence of SSC abnormalities on HR-NECTH compared to a control group without vertigo. These results further implicate the relationship between SSC abnormalities and vertigo. Interestingly, there was not a statistically significant difference between the prevalence rates of SSC abnormalities between ED patients with explained and unexplained vertigo. This is likely due to the clinical heterogeneity within the explained vertigo cohort. These findings suggest that ED patients presenting with vertigo should have their SSC evaluated on HR-NECTH. This may facilitate diagnosis of patients suffering from vertigo, expedite referral to ENT, and may obviate the need for TBCT which would reduce economic and radiation burden to patients.
