“…The advantages and disadvantages of the low-field 0.12-tesla PoleStar system have been described previously [1,2,3, 5]. The advantages include lower costs for a system that is simple to operate and also permits the use of non-MRI compatible surgical instruments.…”

“…An extensive description of the PoleStar N-10 iMRI imaging system has been published previously [1,2,3, 5]. Briefly, the PoleStar N-10 system is a 0.12-tesla, low-field open MR imager with the 5-Gs line located 1.5 m from the magnet isocenter.…”

“…The benefits of iMRI in tumor resection control and in orientation during surgery for multicystic hydrocephalus have been previously documented [1,2,3,4,5,6]. The major advantage of iMRI over conventional surgical navigational systems is the ability to provide an updated data set for real-time navigation.…”

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.

AIm: Use of intraoperative MRI (iMRI) is the highest contemporary supportive means for brain tumor surgery. In this article we describe the issues related to iMRI use in pediatric cranial operations. mAterIAl and methOds: Pediatric cases operated with the aid of Polestar N20 iMRI system are defined and the pros and cons of the system are emphasized. BulGulAr: Özellikle posterior fossa tümörleri için pediatrik olgularda hasta pozisyonlanması daha rahat ve elde edilen görüntü kalitesi daha iyi idi. sOnuÇ: Pediatrik beyin tümörü operasyonlarında iMRI mümkün olduğunca kullanılmalıdır.

Traditional methods to treat colorectal cancer require surgeries, which result in large wound surface. In this study, a flexible tubing was introduced as a cold plasma generator and also a magnetic resonance (MR) imaging antenna to guide plasma for rectal wall treatment in vivo. A healthy rabbit was used to test the feasibility of the two-in-one technique. The safety of plasma was verified by hematoxylin-eosin staining to characterize the rectal tissue. Results showed that the tubing could be not only ignited in vivo, but also be tracked accurately by MR images. And after 15 min treatment, there exhibited no unacceptable damage for rectal cells. In conclusion, this combined device could be feasible for the navigated plasma treatment and provide a valuable tool for potential colorectal cancer treatment in the future.
