“…They concluded that iMRI safely increased the resection of pituitary macroadenoma remnants that were poorly visualized under the operating microscope. Many other studies in the literature using low-field iMRI [9][10][11][12]14,16,[27][28][29][30], including those using an endoscope and iMRI [14,15,28,30], have reached similar conclusions. Among these studies, the most recent one by Vitaz et al who used both endoscopy and iMRI for transsphenoidal surgery of macroadenomas and other pituitary tumors reported GTR rate of 82% achieved at the three-month postoperative MRI.…”

“…Another more common technology is the use of Intraoperative MRI. This technology has been extensively utilized for endoscopic removal of pituitary tumors for more than ten years [3,21]. We have found this exceptionally helpful in cases of giant pituitary tumors (figure 5) and other skull base cases such as meningiomas and craniopharyngiomas (figure 6).…”

“…3,12) The first uses of iMR imaging in transsphenoidal surgery for pituitary adenomas were reported around 2000, 5,20,25) and iMR imaging is now well known to be an effective and safe modality for transsphenoidal surgery of pituitary adenomas. 2,11,24,29,31,33) Detection and visualization of tumor remnants by iMR imaging contributes to an increased rate of complete tumor removal, and prevents unnecessary exploration and injury around normal tissues. 30) iMR imaging can be classified as low (0.12-0.2 tesla), medium (0.5 tesla), or high (À1.5 tesla) field according to the strength of the magnetic field used.…”

The usefulness of 1.5-T high-field intraoperative magnetic resonance (iMR) imaging during transsphenoidal surgery for functioning pituitary adenomas was retrospectively evaluated based on longterm endocrine remission from the records of 14 patients who underwent transsphenoidal surgery with iMR imaging for functioning pituitary microadenomas and small adenomas located in the intrasellar region. The maximum tumor diameter was 9.3 ± 2.6 mm. Patients were diagnosed with acromegaly (n ＝ 7), prolactinoma (n ＝ 4), and Cushing's disease (n ＝ 3). If iMR imaging detected tumor remnants after resection, the resection cavity was reexamined and further resection was performed. Postoperative endocrine follow-up period was mean 33.7 ± 13.3 months. Tumor remnants were detected after the first resection in seven patients. Further resection was performed in five of these patients, and three achieved long-term endocrine remission. As a result, the overall long-term endocrine remission rate was 78.5% (11/14), instead of the 57.1% (8/14) that would be expected if iMR imaging had not been performed. Long-term endocrine remission had a tendency to be associated with the absence of tumor remnants on the final iMR images, but this was not significant (p ＝ 0.09). Long-term endocrine remission was associated with presence of tumor remnants in the cavernous sinus on the final iMR images (p ＝ 0.03). High-field iMR imaging is useful for depicting tumor remnants after resection, and increased the long-term endocrine remission rate for patients with functioning pituitary microadenomas and small adenomas.
