Neuroimaging has transitioned from the laboratory to the clinic at an unprecedented pace, becoming a standard diagnostic, monitoring, and treatment tool for neurological and psychiatric diseases. In this book, a clear description of this revolution is provided, emphasizing how novel imaging techniques are reshaping contemporary medicine. Organized into three sections, the book opens with the examination of brain development, describing how state-of-the-art diffusion MRI reveals the dynamic architecture of the developing brain. The opening chapter emphasizes the promise of early imaging in identifying neurodevelopmental disorders. The second section is dedicated to clinical applications. Chapters cover the correspondence between neuroimaging features and disease, the use of nuclear medicine methodology in dementia, epilepsy, and movement disorders, and the diagnostic value of PET/CT, illustrated by case-based examples. These chapters offer practical insights into enhanced diagnostic accuracy and therapeutic support through multimodal imaging. The third section of the book acquaints readers with interventional and surgical applications. This section illustrates how imaging today is directly applied in therapy, from treatment under imaging guidance to neuronavigation and neuromodulation interventions. Trends for the future, such as the incorporation of AI, portable imaging, and augmented reality into the operating room, are also discussed. Authored by international experts, this book is intended for clinicians, researchers, and students interested in the clinical applications of neuroimaging. It links current research with everyday medical practice using case-based examples and practical frameworks. Neuroimaging - From Research to Clinical Practice is a reference and a guide to how brain imaging shapes modern treatment approaches.
