Positron-Emission Tomography
Research News and Information
Definition of 'Positron-Emission Tomography'An imaging technique using compounds labelled with short-lived positron-emitting radionuclides (such as carbon-11, nitrogen-13, oxygen-15 and fluorine-18) to measure cell metabolism. It has been useful in study of soft tissues such as CANCER; CARDIOVASCULAR SYSTEM; and brain. SINGLE-PHOTON EMISSION-COMPUTED TOMOGRAPHY is closely related to positron emission tomography, but uses isotopes with longer half-lives and resolution is lower. |

BACKGROUND AND PURPOSE: Most studies on mild cognitive impairment (MCI) have been focused on amnestic MCI (aMCI) that is the preclinical stage of Alzheimer's disease (AD). In contrast, only a few studies have involved patients in the preclinical ... Read more...

Noninvasive assessment of cardiac structure and function is essential to understand the natural course of murine infection with Trypanosoma cruzi. Magnetic resonance imaging (MRI) and echocardiography have been used to monitor anatomy and function; ... Read more...

Dopamine (DA) D2 receptor supersensitivity has been linked to an increase in the density of the D2 high-affinity state as measured in vitro. The two- affinity-state model of the D2 receptor predicts that the ex vivo specific binding of ... Read more...
