Retinoblastoma is the most common cause of all intraocular pediatric malignancies. It is caused by the loss of tumor suppressor gene function, although some tumors occur due to oncogene amplification with normal genes. Nearly half of all retinoblastomas occur due to a hereditary germline pathogenic variant, most of which manifest with bilateral tumors. This germline mutation also predisposes to intracranial midline embryonal tumors. Accurate staging of retinoblastoma is crucial in providing optimal vision-, eye-, and life-saving treatment. The has undergone significant changes, resulting in a universally accepted system with a multidisciplinary approach for managing retinoblastoma. The authors discuss the role of MRI and other diagnostic imaging techniques in the pretreatment assessment and staging of retinoblastoma. A thorough overview of the prevailing imaging standards and evidence-based perspectives on the benefits and drawbacks of these techniques is provided. Published under a CC BY 4.0 license.

视网膜母细胞瘤是所有眼内儿科恶性肿瘤中最常见的病因。它是由肿瘤抑制基因功能丧失引起的,尽管一些肿瘤是由于正常基因的癌基因扩增引起的。近一半的视网膜母细胞瘤是由于遗传性种系致病性变异引起的,其中大多数表现为双侧肿瘤。这种种系突变也易导致颅内中线胚胎性肿瘤。准确分期视网膜母细胞瘤对于提供最佳的保视力、保眼和挽救生命的治疗至关重要。该分期系统发生了重大变化,采用了多学科方法,形成了一个普遍接受的系统来管理视网膜母细胞瘤。作者讨论了 MRI 和其他诊断成像技术在视网膜母细胞瘤的预处理评估和分期中的作用。本文全面介绍了现有的成像标准,以及对这些技术的优缺点的循证观点。本文在知识共享署名 4.0 国际许可协议下发表。本文提供了补充材料中关于该文章的知识测试问题。
