The Evaluation of Primary Brain Tumors: The Role of CT and MRI

Abstract

Primary brain tumors are a serious problem for neurology and oncology. Imaging serves as an indispensable cornerstone in the management of patients grappling with brain tumors. Primary brain tumors impose a substantial burden on individuals' lives and on public healthcare systems.]This literature review delves into the essential roles of MRI and CT in diagnosing and evaluating primary brain cancers. It discusses emerging imaging techniques, contrast agents, and functional imaging modalities that further enhance the accuracy of brain tumor assessment By summarizing the latest research, the review underscores how the synergy between MRI and CT contributes to more precise diagnosis, treatment planning, and post-treatment monitoring of individuals with brain tumors. Imaging techniques, notably computed tomography (CT) and magnetic resonance imaging (MRI), have evolved significantly in their ability to detect and characterize brain tumors. Computed tomography is non- invasive and provides three-dimensional cross-sectional anatomy of the brain, which can be reformatted in multiple planes. Computed tomography provides more detail about the nature of calcification and can characterize soft tissue abnormalities with high contrast and good spatial resolution. Magnetic resonance imaging is noninvasive and provides three-dimensional cross-sectional anatomy of the brain, which can be acquired in multiple planes. The dominant modality used is MRI because of its superior image resolution, speed of acquisition, and high safety profile for patients.
