One of the greatest neuro-oncological concern remains the lack of knowledge about the etiopathogenesis and physiopathology of gliomas. Several studies reported a strict correlation between radiological features and biological behaviour of gliomas; in this way the velocity of diametric expansion (VDE) correlate with lower grade glioma aggressiveness. However, there are no the same strong evidences for high grade gliomas (HGG) because of the lack of several preoperative MRI.

原发高级别胶质瘤的放射学评估：直径扩张速度和加速时间研究

最大的神经肿瘤学问题之一仍然是缺乏关于神经胶质瘤的发病机制和病理生理学的知识。几项研究报告了神经胶质瘤的放射学特征和生物学行为之间的严格相关性；通过这种方式，直径扩张速度 (VDE) 与较低级别的胶质瘤侵袭性相关。然而，由于缺乏几个术前 MRI，高级别胶质瘤 (HGG) 没有同样强有力的证据。
