Measurement of anterior and posterior sagittal displacements. The contour of a PitNET/pituitary adenoma on three-dimensional T2-weighted imaging (3D-T2WI) in the sagittal plane (a) is superimposed on the corresponding reconstructed sagittal diffusion-weighted imaging (DWI) (c). Geometric distortion (b, arrows) is determined as anterior and posterior displacements between DWI and the corresponding 3D-T2WI (c). The boxplots show results of anterior and posterior sagittal displacements (d). Anterior sagittal displacement is the least in RDC-DWI and is significantly lower in B0-corrected-DWI than in AP-DWI. Posterior sagittal displacement is significantly lower in RDC-DWI and B0-corrected-DWI than in AP-DWI. 3D-T2WI, Three-dimensional T2-weighted imaging; AP, Anterior-posterior; DWI, Diffusion-weighted imaging; EPI, Echo-planar imaging; PA, Posterior-anterior; PitNET, Pituitary neuroendocrine tumor; RDC-DWI, Reverse encoding distortion correction DWI
