Relevant information including the date of publication, the first author and the city where the study was reported from are listed. Where available, data on the total number of tumors studied, the number of non-functioning pituitary adenomas in the series, as well as the size class are tabulated. The reports were analyzed to identify the number of unexpected residuals detected by intraoperative imaging, the number of cases that were re-explored following imaging, and finally, the number of cases where this led to further resection of residual adenoma. GE – general electric, NFPA – non-functioning pituitary adenoma, T – tesla, Ref – citation reference number, TSS – transsphenoidal surgery.
