Modern neuroimaging tools provide exceptional chances for understanding brain neuroanatomy and its role in health and illness. Each feasible technique carries with it a specific balance of potentials and drawbacks, such that converging evidence formed on multiple methods provides the strongest approach for enhancing our knowledge in the fields of clinical and cognitive neuroscience. The aim of this book is to provide a "snapshot" of present developments using well established and newly emerging techniques. The book includes the role of SPECT in the diagnosis of idiopathic Parkinson's disease, developments in dopamine transporter imaging and the application of non-conventional neuroimaging techniques in neuropsychiatric systemic lupus erythematosus (NPSLE) is discussed in detail.
