Synopsis

MRI is a primary imaging method for the evaluation of pituitary adenomas (PAs). However, it is challenging to identify the postoperative residual tumors using traditional techniques. A recent approach Golden-angle Radial Sparse Parallel (GRASP)-DCE, and the novel simultaneous multi-slice (SMS) readout-segmented EPI technique (RESOLVE) procedures were performed to assess the residual tumors of postoperative PAs. And the residual tumors were observed as slow enhancement in GRASP images while manifesting as hyperintense in SMS-RESOLVE images. Thus, both of them are promising techniques for the evaluation of postoperative residual PAs.
