Neuroimaging is the use of various techniques that directly or indirectly assess the structure or function of the nervous system. Computed tomography (CT) and magnetic resonance imaging (MRI) are the most widely used modalities in routine clinical practice.
This article discusses the common indications and limitations of CT and MRI, and the importance of clinical correlation.
There is a wide range of applications for neuroimaging but with some limitations, including potential unnecessary anxiety in patients and unwarranted further investigations as a result of incidental findings. The reliability of imaging studies depends on careful correlation with the clinical picture.
