In this study, we aimed to determine whether intratympanic (IT) or intravenous (IV) injection of gadolinium is more suitable for labyrinthine lymph imaging of patients with vertigo disease. The corresponding MR images with IV and IT injection were thus systematically compared. While comparable detection of endolymphatic hydrops were shown using both injection methods, higher image contrast between affected and unaffected sides of perilymph region were found using IV method than using IT method. We therefore, demonstrated that IV method can be further applied in clinical diagnosis for patients with vertigo disease.
