Positron emission tomography measures of endogenous opioid neurotransmission and impulsiveness traits in humans.

29 Sep 2009 CONTEXT: The endogenous opioid system and opioid mu receptors (mu-receptors) are known to interface environmental events, positive (eg, relevant emotional stimuli) and negative (eg, stressors), with pertinent behavioral responses and to regulate ... Read more...

Resting metabolic activity in the cingulate cortex and vulnerability to posttraumatic stress disorder.

29 Sep 2009 CONTEXT: Recent neuroimaging research has revealed functional abnormalities in the anterior cingulate cortex, amygdala, and hippocampus in individuals with posttraumatic stress disorder (PTSD). OBJECTIVE: To determine whether resting functional ... Read more...

Lesion quantification in oncological positron emission tomography: a maximum likelihood partial volume correction strategy.

29 Jun 2009 A maximum likelihood (ML) partial volume effect correction (PVEC) strategy for the quantification of uptake and volume of oncological lesions in 18F-FDG positron emission tomography is proposed. The algorithm is based on the application of ML ... Read more...

Technical information about 'Positron-Emission Tomography'

Definition: 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.
