Background. Imaging plays a key role in the diagnosis of central nervous system (CNS) metastases. Objective. In this review the role of magnetic resonance imaging (MRI) and computed tomography (CT) in the work-up of cerebral metastases is presented. In addition to characteristic imaging findings technical aspects for improved detection of CNS metastases and differential diagnoses are shown. Material and methods. This review is based on own experience and relevant recent publications. Results. In the diagnosis of CNS metastases contrast-enhanced MRI is the radiological method of choice. The sensitivity can be further increased by increasing contrast medium dose as well as the use of various magnetization transfer techniques. Functional MRI techniques, such as magnetic resonance spectroscopy, perfusion and diffusion-weighted imaging, diffusion tensor imaging and dynamic contrast-enhanced imaging can further improve the differential diagnosis and detection of recurrent disease. If CT is used for diagnostics of cerebral metastases it should be performed with increased contrast combined with a scan delay. Conclusions. Contrast-enhanced MRI ideally using a multimodal protocol is the most sensitive method for the detection of CNS metastases and should therefore be preferred to CT. © 2013 Springer-Verlag Berlin Heidelberg.
