We aimed to explore the optimal scan parameters of 3D-FLAIR technique in labyrinthine lymph imaging for patients with vertigo disease. With different scan times and scan baselines applied, the corresponding 3D-FLAIR images were systematically compared. We found that the optimal scan time was 6hours after intravenous administration of GBCM. Additionally, the optimal scan baseline, aiming to obtain the relative maximum areas of the saccule, utricle and lateral semicircular canal to be displayed at the same level, is about 10.74±2.24 degrees from the anterior skull base. Therefore, using these optimal parameters, an accurate determination of endolymphatic hydrops can be achieved.
