Limitations
One of the limitations of our study was that our data set that looked at postoperative MRI outcomes for residual tumors, was seen in a smaller sample size of n=19 compared to our initial group of n=56 patients that underwent iMRI. A larger sample size may allow for a better understanding of postoperative residual tumor occurrence amongst patients undergoing iMRI for resection of pituitary tumors. We suggest that this be studied further.
