Neuroradiology of brain tumors

Neuroradiology plays a vital role in the evaluation of intracranial neoplasms. The radiologist can offer a differential diagnosis of tumor type based on imaging characteristics, enhancement patterns, and the amount of surrounding edema. Associated complications are usually evident on standard radiologic examinations. This article discusses such standard imaging techniques and some of the new techniques, which are proving to be very useful in providing prognostic information.
