PoleStar N-10, the miniature MRI scanner designed for intraoperative scanning, made a splash in the April 2001 issue of Neurosurgery. Results from 20 patient cases indicated that neurosurgeons performed procedures more accurately and more confidently using this device, according to the study authors. The study examined a broad range of neurosurgical procedures, including removal of low-grade lesions and a mesiotemporal tumor (causing intractable epilepsy), as well surgical treatment of pituitary adenoma. In each case, the resection was successful, and no complications related to use of the device were observed. Surgical results were confirmed and verified with conventional diagnostic MRI after the operation. PoleStar was developed by Israel-based Odin Medical Technologies (SCAN 11/8/00).
