Journal ArticleDOI

Grading of astrocytomas: A simple and reproducible method

TL;DR: In ordinary astrocytomas, each of the four histologic criteria, as well as the resultant grade, were strongly correlated to survival, and based upon the Cox Model, grade was found to be the major prognostic factor, superceding the effects of age, sex, and location.
Journal ArticleDOI

Imaging-based stereotaxic serial biopsies in untreated intracranial glial neoplasms

TL;DR: Histological analysis of 195 biopsy specimens obtained from various locations within the volumes defined by CT and MRI revealed that contrast enhancement most often corresponded to tumor tissue without intervening parenchyma, and isolated tumor cell infiltration extended at least as far as T2 prolongation on magnetic resonance images.
Journal ArticleDOI

Glial neoplasms: dynamic contrast-enhanced T2*-weighted MR imaging.

TL;DR: Echo-planar perfusion imaging is useful in the preoperative assessment of tumor grade and in providing diagnostic information not available with conventional MR imaging.
