Fig. 5

A 68-year-old woman with residual non-functioning PitNET/pituitary adenoma after surgery. Axial 3D-T2WI (a), axial b = 1,000 s/mm2 images of AP-DWI (b), B0-corrected-DWI (c), and RDC-DWI (d) are shown. The residual PitNET/pituitary adenoma cannot be clearly distinguished from the right cavernous sinus on axial 3D-T2WI (a). There is severe distortion, susceptibility artifact, and signal pileup around the residual PitNET/pituitary adenoma and the left trigeminal nerve on AP-DWI (b, arrows). B0-corrected-DWI and RDC-DWI depict undistorted residual PitNET/pituitary adenoma without apparent susceptibility artifact (c and d). Compared with B0-corrected DWI, there is less blurring on RDC-DWI, particularly in the sphenoid sinus (c, arrowheads), and there are fewer susceptibility artifacts in the left trigeminal nerve (c, arrow). 3D-T2WI, Three-dimensional T2-weighted imaging; AP, Anterior-posterior; DWI, Diffusion-weighted imaging; PitNET, Pituitary neuroendocrine tumor; RDC-DWI, Reverse encoding distortion correction DWI
