Abstract
MRI is undoubtedly at the forefront of brain tumor imaging. It is the imaging study of choice, not only for diagnosis but also as a preferred modality for characterization and treatment planning of brain tumors. CT is superior in detecting calcification, hemorrhage, and in evaluating bone changes related to tumors. Patients with pacemakers or metallic devices, as well as critically ill or unstable patients, represent some of the specific areas in which CT is the diagnostic modality of choice. The arrival of multichannel, spiral CT has rejuvenated its role because of the high speed scanning which facilitates sophisticated multiplanar three-dimensional (3D) imaging as well as dynamic imaging (i.e., CT-perfusion [CTP] and CT angiography [CTA]). These advanced techniques are extremely useful in preoperative localization, intraoperative navigation, and radiation therapy targeting.
