Abstract

The majority of primary brain tumors in adults are found in the supratentorial compartment, while tumors in pediatric patients are usually infratentorial in location. This unit presents basic protocols for imaging all types of primary intra‐axial brain tumors, whether infiltrative (i.e., astrocytoma, oligodendroglioma, lymphoma) or circumscribed (i.e., ganglioglioma, cystic astrocytoma). Specific modifications are discussed where necessary. The sequences described in this unit are based on a 1.5 T scanner (Echospeed GE Medical Systems), but can be expected to be equally applicable to other field strengths and scanners from other manufacturers.
