MRI (Magnetic Resonance Imaging) in Psychiatry
In recent years, structural and functional magnetic resonance imaging has opened up new avenues to the study of psychiatric disorders. A number of structural changes characteristic for different psychiatric diseases could be delineated by the use of magnetic resonance imaging (MRI). Functional magnetic resonance imaging (fMRI) enables the in vivo investigation of cerebral neuronal activation under cognitive or behavioral activation paradigms. Magnetic resonance spectroscopy (MRS) allows for the study of defined neurochemical substances or pharmacological agents in the human brain. This article presents an overview of the basic principles of the different MRI techniques and representative re…
D2-receptor imaging with [123I]IBZM and Single Photon Emission Tomography in psychiatry: a survey of current status
D2-dopamine receptors can be visualized in the human brain in vivo by Single Photon Emission Tomography (SPECT) and the radiolabeled benzamide [123I]IBZM. The present paper reviews the current status of this type of functional brain imaging with respect to basic methodological aspects, data analysis and quantification. The results from published clinical studies in different psychiatric patient populations and normal controls with [123I]IBZM are reviewed. [123I]IBZM-SPECT is a powerful tool for the investigation of D2-dopamine receptor status in psychiatric disorders, different types of drug treatment as well as therapeutic and side effects of pharmacologic agents. However, there still is a…
