The increasingly biological emphasis in psychiatry has meant that even the so-called "functional" disorders are now considered to involve structural or biochemical abnormalities. This book explains to the clinician the principles, applications and clinical interpretation of brain imaging. It is aimed at clinical psychiatrists at all levels, but particularly those who have no detailed knowledge of the subject. It will also be most useful to clinical researchers in biological psychiatry for whom brain imaging is a vital experimental tool and to neuroradiologists and neurologists.
