METHODS:
We performed a retrospective review of a total of 56 patients who
underwent iMRI guided transsphenoidal pituitary tumor resection over a
period between November 2011 to April 2018 at Northwestern Medicine
Central Dupage Hospital. We defined gross-total resection as removal of
the pituitary tumor in its entirety as seen during intraoperative MRI
use. The endoscopic endonasal transsphenoidal approach was used to
resect all of the pituitary tumors in this study. The source of the
patient data that was acquired for this study was through the use of
electronic medical records. Intraoperative and post-operative MRI
reports were interpreted and used during analysis. The type of MRI used
during surgery was the Imirs Intraoperative MRI system which supports
1.5 to 3 Tesla. This study was approved by the institution’s review
board (IRB #18-054). The reporting guideline for our study includes our
results, discussions, and conclusions.
