Intraoperative MRI for transphenoidal procedures: short-term outcome for 100 consecutive cases.

Background: The majority of pituitary lesions are benign and can be cured with complete surgical resection. However, the transsphenoidal technique (the most common approach for pathology in this region) is limited by poor visualization and anatomical constraints. This can lead to incomplete tumor resection and thus increased recurrence rates.

The use of intraoperative MRI for the treatment of glioblastoma multiforme.

Outcome for patients with glioblastoma multiforme (GBM) is improved with aggressive surgical resection followed by standard chemotherapy and radiation therapy. Intraoperative MRI (iMRI) is a recent surgical advancement that gives neurosurgeons direct radiographic feedback throughout a surgical procedure and thus enables maximal surgical resection of such lesions. We reviewed our series of 35 cases in 29 patients who underwent surgical resections of their GBM's using iMRI.
