Figure 1: Useful imaging techniques utilized in neuropsychiatric disease treatment. PET has the ability to detect cerebral metabolism, blood flow, and neurotransmitter activity. SPECT has the ability to detect cerebral blood flow and neurotransmitter activity. Magnetic resonance spectroscopy (MRS) can detect the molecular milieu of particular brain areas. fMRI is able to measure changes in cerebral blood flow across a variety of conditions related to disease state and activation states. |
