ABSTRACT
Brain metastases are the most common adult tumours of the central nervous system. The brain parenchyma is most frequently affected, though a significant proportion of tumours also involve the meninges and calvarium. The incidence of brain metastases is increasing, in part due to the improvements in medical imaging technology. Magnetic resonance imaging is the best modality to identify brain metastases; however, challenges still remain in differentiating these tumours from other solitary brain lesions as well as assessing treatment-related response. This chapter examines the imaging findings of brain metastases and assesses the role of conventional and advanced imaging techniques in their initial diagnosis and management follow-up.
