The majority of investigations on the utility of and indications for intraoperative magnetic resonance imaging (iMRI) have been in adult patients. We report our initial experience utilizing low-field iMRI in pediatric patients.
We performed 21 procedures on 20 patients aged 2 months to 18 years (mean 8.9 years) utilizing the PoleStar -10 iMRI system. The procedures included 15 craniotomies, 2 shunts, and 1 each of the following surgeries: transsphenoidal, craniotomy/transsphenoidal, cranioplasty, and endoscopic biopsy and fenestration. Treated lesions included low-grade astrocytoma (5), craniopharyngioma (3), cortical dysplasia (3), hydrocephalus (2), and others (8). The number of scans ranged from 2 to 5 with a mean of 3.2. Intraoperative imaging and navigation provided valuable information on the extent of resection and catheter placement. In eight procedures it influenced the surgical strategy. No untoward events attributable to the system occurred.
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.
大多数关于术中磁共振成像（iMRI）效用和适应证的研究针对的是成年患者。我们报告我们在儿科患者中使用低场iMRI的初步经验。
我们使用PoleStar -10 iMRI系统对20例年龄在2个月至18岁（平均8.9岁）的患者进行了21例手术。手术包括15例开颅手术、2例分流术，以及以下手术各1例：经蝶窦手术、开颅/经蝶窦手术、颅骨成形术、内镜活检和开窗术。治疗的病变包括低级别星形细胞瘤（5例）、颅咽管瘤（3例）、皮质发育异常（3例）、脑积水（2例）和其他（8例）。扫描次数为2至5次，平均3.2次。术中成像和导航为切除范围和导管放置提供了有价值的信息。在8例手术中，它影响了手术策略。未发生与该系统相关的不良事件。
低场PoleStar -10 iMRI系统可以安全地辅助儿科神经外科医生治疗多种疾病。除神经导航外，它还提供有关切除范围、实时引导导管放置和避免并发症的信息。
