Abstract：
The 2021 World Health Organization classification of CNS tumours was greeted with enthusiasm as well as an initial potential overwhelm. However, with time and experience, our understanding of its key aspects has notably improved. Using our collective expertise gained in neuro-oncology units in hospitals in different countries, we have compiled a practical guide for radiologists that clarifies the classification criteria for diffuse gliomas in adults. Its format is clear and concise to facilitate its incorporation into everyday clinical practice. The document includes a historical overview of the classifications and highlights the most important recent additions. It describes the main types in detail with an emphasis on their appearance on imaging. The authors also address the most debated issues in recent years. It will better prepare radiologists to conduct accurate presurgical diagnoses and collaborate effectively in clinical decision making, thus impacting decisions on treatment, prognosis, and overall patient care.
摘要：
2021年世界卫生组织对中枢神经系统肿瘤的分类受到了热情和最初的潜在压倒。然而,有了时间和经验，我们对其关键方面的理解有了显著提高。利用我们在不同国家医院的神经肿瘤科获得的集体专业知识，我们为放射科医师编制了实用指南,阐明了成人弥漫性神经胶质瘤的分类标准.它的格式清晰简洁，便于将其纳入日常临床实践。该文件包括分类的历史概述，并强调了最近最重要的补充。它详细描述了主要类型，重点是它们在成像上的外观。作者还谈到了近年来争论最多的问题。它将更好地准备放射科医生进行准确的术前诊断，并在临床决策中有效地合作，从而影响治疗决策，预后,和整体病人护理。
