Abstract:
Objective To discuss the value of Valsalva experiment combined with improved MRI tilt tomography applying on the pharyngeal ostium of eustachian tube opening function of patients with nasopharyngeal carcinoma.Methods 1 7 cases with patholog-ically proved NPC underwent conventional MRI plain and enhanced scan.In the eustachian tube area oblique transection T2 WI and T1 WI scanning was done before and after the Valsalva experiment.The invasion of eustachian tube and its surrounding structures was analyzed and the eustachian tube function was evaluated.Results Valsalva experiments combined with improved MRI trans-verse oblique scan could clearly display the whole structure of the eustachian tube and surrounding tissue invasion compared with conventional scanning MR scan.And it could better evaluate the eustachian tube opening function for patients suffered nasopharynge-al carcinoma.Conclusion Valsalva experiments with improved MRI oblique transverse imaging could achieve individualized scan of the eustachian tube,and could be used for evaluating the pharyngeal opening function of eustachian tube in patients with nasopharyn-geal carcinoma.
