This study aimed to investigate the feasibility of ultrashort echo time (UTE) in visualizing the Eustachian tube (ET). Nineteen healthy volunteers were involved in this study. The quality of images was rated by two experienced radiologists using a double-blind method. Using the depiction of the cartilaginous part of the ET from standard T2-weighted images and that of the bony part from CT acquisition as reference points, UTE images were analyzed. The results indicate that UTE can not only display ET cartilage, but also display bone structure. This could lead to the application of whole-ET imaging in one MR exam.
