Utilization of iMRI for Transsphenoidal Resection of Pituitary Macroadenomas
Utilization of iMRI for Transsphenoidal Resection of Pituitary Macroadenomas
The investigators are studying the utility of intra-operative magnetic resonance imaging
 (iMRI) during transsphenoidal pituitary surgery for large macroadenomas by randomizing
 patients to either an intra-operative MRI after resection, or no intra-operative MRI. The
 investigators will then count the number of gross total resection in each group of patients
 and also the complications related to surgery.
Inclusion Criteria:

 -  Adults 18-90

 -  Pituitary macroadenoma ( >2.5 cm) in MRI

 -  Elect for transsphenoidal surgery

 Exclusion Criteria:

 -  Children (age < 18)

 -  Pituitary macroadenoma

 -  Unable to tolerate MRI
