“…We achieved a resection rate of 82% in a smaller cohort of 22 pediatric patients using IOUS. Samdani et al demonstrated that a low-field iMRI in pediatric neurosurgery provides additional information for resection and real-time catheter placement [22], which we could also confirm with the IOUS technique. To date, there are no published prospective randomized studies comparing outcomes and resection control percentages between these two intraoperative imaging modalities.…”

Purpose Intraoperative ultrasound (IOUS) has become a useful tool employed daily in neurosurgical procedures. In pediatric patients, IOUS offers a radiation-free and safe imaging method. This study aimed to evaluate the use of a new real-time 3-D IOUS technique (RT-3-D IOUS) in our pediatric patient cohort. Material and methods Over 24 months, RT-3-D IOUS was performed in 22 pediatric patients (8 girls and 14 boys) with various brain tumors. These lesions were localized by a standard navigation system followed by analyses before, intermittently during, and after neurosurgical resection using the iU22 ultrasound system (Philips, Bothell, USA) connected to the RT-3-D probe (X7-2). Results In all 22 patients, real-time 3-D ultrasound images of the lesions could be obtained during neurosurgical resection. Based on this imaging method, rapid orientation in the surgical field and the approach for the resection could be planned for all patients. In 18 patients (82%), RT-3-D IOUS revealed a gross total resection with a favorable neurological outcome. Conclusion RT-3-D IOUS provides the surgeon with advanced orientation at the tumor site via immediate live two-plane imaging. However, navigation systems have yet to be combined with RT-3-D IOUS. This combination would further improve intraoperative localization.

“…[3][4][5][6][7][8][9][10][11] However, the benefits of this expensive technology have not been uniformly demonstrated in the literature. [11][12][13][14] With respect to high-field-strength iMRI, typically defined as 1.5T or higher, its impact on operating room and anesthesia time and the incidence of MR imaging-related complications, particularly in the pediatric population, have been the topic of limited publications. 3,[15][16][17] We performed a retrospective review of our 24-month experience with a 3T-iMRI at a tertiary care children's hospital to determine the impact of this tool on surgical planning, workflow, and patient outcomes.…”

Objectives: Intraoperative MRI (iMRI) is used mainly in the adult neurosurgical population. The main indications for iMRI usage are resection control and updated intraoperative navigation capabilities. In this paper we present our experience using this technique in children. Specific advantages of iMRI for this age group are discussed. Methods and Results: We retrospectively reviewed 31 pediatric neurosurgical procedures in which a portable iMRI system was used. The indications for iMRI usage were preoperative navigation, resection control during tumor removal, shunt placements, and needle biopsy. In 7 children the use of the iMRI changed the course of the surgical procedure. Operative morbidity and mortality were not increased with use of the iMRI. Conclusions: iMRI systems have advantages for the pediatric neurosurgical population, including both real-time basic navigation and improved resection control.

Use of a compact intraoperative low-field magnetic imager in pediatric neurosurgery

Abstract: The low-field PoleStar -10 iMRI system can safely assist pediatric neurosurgeons treating a variety of diseases. In addition to neuronavigation it provides information on extent of resection, real-time guided catheter placement, and avoidance of complications.
