Molecular imaging is expected to change the face of drug discovery and development. The ability to link imaging to biology for guiding therapy should improve the rate at which novel imaging technologies, probes, contrast agents, drugs and drug delivery systems can be transferred into clinical practice. Nuclear medicine imaging, in particular, positron emission tomography (PET) allows the detect...

Radioisotope scanning is very important in evaluation, diagnosis and proper treatment of urinary tract infection (UTI) and vesicoureteral reflux (VUR) because of high sensitivity of this technique and less radiation dose delivered to the patients. This is a descriptive cross-sectional study to determine the frequency VUR in a group of children aged 28 days to 14 years referred to our depa...

Risks of diagnostic imaging include cancer from radiation exposure and nephrogenic systemic fibrosis. The increase in volume of imaging between 1980 and 2006 has led to a sixfold increase in annual per capita radiation exposure. It is predicted that 2 percent of future cancers will be caused by radiation from computed tomography (CT) exposure. Gadolinium contrast media should be avoided in pati...

A novel multi-source energy harvester based on solar and radioisotope energy sources is designed and simulated in this work. We established the calculation formulas for the short-circuit current and open-circuit voltage, and then studied and analyzed the optimization thickness of the semiconductor, doping concentration, and junction depth with simulation of the transport process of β particles ...

Positron emission tomography (PET) is routinely used for medical imaging; a current surge in published geoscientific research utilizing this modality also infer increasing interest in-situ PET imaging core analysis. Excellent signal to noise ratio coupled with high temporal and spatial resolution suggest that might become the new method-of-choice Obstacles related production, transfer handling ...
