Positron emission tomography using fluorine-18 deoxyglucose in evaluation of coronary artery bypass grafting.
Value and limitation of stress thallium-201 single photon emission computed tomography: comparison with nitrogen-13 ammonia positron tomography.
Since stress-delayed SPECT with single tracer injection detected fewer transient defects, it may underestimate the presence of myocardial ischemia, compared with high resolution PET imaging with two tracer injections.
Quantitative analysis of tissue distribution of the B16BL6-derived exosomes using a streptavidin-lactadherin fusion protein and iodine-125-labeled biotin derivative after intravenous injection in…
The results of the present study indicate that (125) I-labeling of exosomes using SAV-biotin system is a useful method to quantitatively evaluate the amount of exogenously administered exosome delivered to each organ and that the liver is the major organ in the clearance of exgenously administered B16BL6-derivedExosomes.
Development of a 111In-labeled peptide derivative targeting a chemokine receptor, CXCR4, for imaging tumors.
(18)F-FDG accumulation in atherosclerotic plaques: immunohistochemical and PET imaging study.
The results suggest that macrophages are responsible for the accumulation of (18)F-FDG in atherosclerotic lesions, which should be useful for the selective detection of vulnerable plaques.

In subcellular fractions of tumor cells, Cu-ATSM was reduced mainly in the microsome/cytosol fraction rather than in the mitochondria, completely different from that found in normal brain cells.
Temporal Change in Human Nicotinic Acetylcholine Receptor After Smoking Cessation: 5IA SPECT Study
Because the upregulation of the nAChRs of the smokers after chronic exposure of the nicotine was downregulated to the nonsmokers' level by around 21 d after smoking cessation, the up regulation is a temporary effect.

Opioid receptors are molecules, or sites, within the body that are activated by opioid substances that inhibit the transmission of impulse in excitatory pathways within the human body system.
