Abstract
INTRODUCTION: An intraoperative MR imaging system, based on a moving, 1.5-tesla magnet, has been developed for neurosurgery. The high magnetic field allows the rapid acquisition of a variety of high-resolution MR sequences (i.e., T1, T2, MRA, EPI) during a surgical procedure. Intrusion upon neurosurgical techniques and equipment is minimized as the magnet is removed from the surgical field during operation. The data acquired during the development and application of this system has demonstrated its value. METHODS: The mobile MR system has been used to assist 176 craniotomies and 7 spinal procedures on patients harboring the spectrum of neurosurgical cranial and cervical disease. Lesions include glioma, meningioma, schwannoma, craniopharyngioma, AVM, cavernoma, mesial temporal sclerosis, cord tumor, etc. RESULTS: The value and effectiveness of this system was particularly evident in three patient groups. Among patients with pituitary adenoma intraoperative images showed unexpected residual tumor in 12 (67%) of 18 patients. In 9...
