Popis: Purpose: To identify and measure the mean size of the utricular macula using 3-T imaging. Methods: One hundred one examinations using a 3-T magnetic resonance scanner and standard temporal bone protocol were performed over a 9-month period. Asymptomatic sides were then retrospectively evaluated using the axial T2-driven equilibrium sequence (0.3-mm slice thickness). We performed the following analyses: (1) reported frequency at which this structure could be identified and (2) calculated the mean size of the utricular macula. Results: The utricular macula was identified in all 101 cases as an ellipsoid area of T2 hypointensity in the utricle. The average anteroposterior x transverse x craniocaudal dimensions were 1.7 x 1.5 x 1.0 mm. Conclusions: The utricular macula is consistently identified with 3-T imaging in asymptomatic patients.
