Abstract
Central nervous system (CNS) tumors are relatively rare, and their diagnosis, therapeutic management, and follow-up represent challenges. However, the various available imaging methods no longer provide exclusively descriptive anatomical information. Advanced imaging techniques now allow for the assessment of functional parameters, thus maximizing the potential of these techniques for diagnosis and treatment assessment. In the present chapter, we discuss the role of these techniques in the diagnosis and treatment planning of CNS neoplasms. In addition, we describe the main features of intra-axial primary and secondary neoplasms as well as their differentiation from nonneoplastic, space-occupying lesions.
