چکیده

This study documented marked accumulation of cocaine in the human and baboon heart, which was not inhibited by desipramine pretreatment. However, cocaine inhibited 6-[18F]fluoronorepinephrine uptake in heart to the same degree as did desipramine (Fowler et al. 1994). Since uptake of [18F]norepinephrine in the heart is a function of its uptake by the NE transporter (Fowler et al. 1994), its inhibition by cocaine corroborates in vivo a significant interaction of cocaine with this transporter.

The effect of fasting on Positron Emission Tomography (PET) imaging

As a nuclear approach, Positron Emission Tomography (PET) is a functional imaging technique which is based on the detection of gamma ray pairs emitted by a positron-emitting radionuclide. There are certain limitations to this technique such as normal tissue uptake. Therefore, it has been recommended that patients prepare before scanning. Fasting for a short while before PET imaging is an exampl...

Detection of Alzheimer\\\\\\\'s Disease using Multitracer Positron Emission Tomography Imaging

Alzheimer's disease is characterized by impaired glucose metabolism and demonstration of amyloid plaques. Individual positron emission tomography tracers may reveal specific signs of pathology that is not readily apparent on inspection of another one. Combination of multitracer positron emission tomography imaging  yields promising results. In this paper, 57 Alzheimer's disease neuroimaging ini...

EEG and evoked potentials alterations in cocaine-dependent individuals.

After two decades of epidemic cocaine use and extensive animal research, what is known about the effects of prolonged exposure to cocaine on the central nervous system (CNS) comes from human findings. Reports of neurological and cerebrovascular infarcts attributed to cocaine abuse and studies investigating CNS function of abstinent cocaine-dependent patients provide important insights into prol...

Calculation of Positron Distribution in the Presence of a Uniform Magnetic Field for the Improvement of Positron Emission Tomography (PET) Imaging Using GEANT4 Toolkit

Introduction Range and diffusion of positron-emitting radiopharmaceuticals are important parameters for image resolution in positron emission tomography (PET). In this study, GEANT4 toolkit was applied to study positron diffusion in soft tissues with and without a magnetic field for six commonly used isotopes in PET imaging including 11C, 13N, 15O, 18F, 68Ga, and 82Rb. Materials and Methods GEA...
