Patients with chiasmatic-hypothalamic low-grade glioma (CHLGG) have frequent MRIs with gadolinium-based contrast agents (GBCA) for disease monitoring. Cumulative gadolinium deposition in the brains of children is a potential concern. The purpose of this study is to evaluate whether MRI with GBCA is necessary for determining radiographic tumor progression in children with CHLGG.

钆对于患有交叉下丘脑低级别胶质瘤的儿童的 MR 成像监测不是必需的

患有交叉下丘脑低级别胶质瘤 (CHLGG) 的患者经常使用基于钆的造影剂 (GBCA) 进行 MRI 以监测疾病。儿童大脑中的累积钆沉积是一个潜在的问题。本研究的目的是评估 GBCA 的 MRI 是否对于确定 CHLGG 儿童的影像学肿瘤进展是否必要。
