Note. The result of the thickness measured on the axial T1WI, T2WI, and 3D FSPGR images were compared between deep-learning-based reconstruction images and conventional reconstruction images, deep-learning-based reconstruction images and 3D FSPGR images, and conventional reconstruction images and 3D FSPGR images. T1WI_O = original T1-weighted FSE images, T1WI_DL= deep learning–reconstructed T1-weighted FSE images, T2WI_O = original T1-weighted FSE images, T2WI_DL = deep learning–reconstructed T2-weighted FSE images, 3D FSPGR= three-dimensional fast spoiled gradient-recalled images. SD = standard deviation; %CV = percent coefficient of variation (SD/mean). SP = septal cartilage, ULC = upper lateral cartilage and LLC = lower lateral cartilage. Significant p values are expressed in bold.
