Modern neuroimaging: the meaning behind the pictures
Recent technological advances have expanded the role of magnetic resonance imaging to include mapping the brain’s dynamic function.
Advances in physics and computing over the last decade have led to the development of astonishing brain imaging techniques that now allow clinicians to examine the complementary aspects of brain structure and function with excellent spatial resolution. The combination of magnetic resonance imaging (MRI) technology, sophisticated signal processing and advanced statistical and visual-isation methodologies now make it possible to study aspects of the brain’s dynamic function and the interconnections between different brain regions. We describe two examples of these new functional imaging techniques and their use in clinical practice.
