Preoperatively knowing if a pituitary adenoma is adhering to the optic chiasm would help to predict the risk of surgically induced vision loss. MR-elastography based slip interface imaging has been successfully developed to predict tumor adhesion using normalized octahedral shear strain (NOSS). This pilot study demonstrates the feasibility of acquiring NOSS at ~1mm high resolution using a newly developed distortion-free EPI-MRE technique on a high-performance compact 3T system. With further development, this technique will have great potential to identify adhesion between pituitary adenomas with the adjacent optic chiasm.
