Overview
CT
The initial diagnosis of a tumor is made with a radiographic study (MRI[1] or CT-). If CT was performed first, a MRI is usually performed as the images are often more detailed and may reveal previously undetected metastatic tumors in other locations of the brain.
The tumors' appearance on CT and MRI are nonspecific, tending towards large size, calcifications, necrosis (tissue death),and hemorrhage (bleeding). Radiological studies alone cannot identify AT/RT; a pathologist almost always has to evaluate a brain tissue sample.
