Imaging Cellular Proliferation in Prostate Cancer with Positron Emission Tomography

Prostate cancer remains a major public health problem worldwide. Imaging plays an important role in the assessment of disease at all its clinical phases, including staging, restaging after definitive therapy, evaluation of therapy response, and prognostication. Positron emission tomography with a number of biologically targeted radiotracers has been demonstrated to have potential diagnostic and...

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...

Atherosclerosis is dependent on a number of cellular processes from initial endothelial injury to sequestration of lipid in the subendothelial space and activation of immune cells. Risk factors for predicting the development of atherosclerosis are well established, as are the various imaging techniques available to assess the burden of atherosclerosis in patients with symptomatic disease. Howev...

Noninvasive cardiovascular imaging in rheumatoid arthritis: current modalities and the emerging role of magnetic resonance and positron emission tomography imaging.

OBJECTIVES Rheumatoid arthritis (RA) is associated with premature atherosclerosis and increased prevalence of cardiovascular disease. The objective of this review is to summarize current and emerging imaging modalities for the evaluation of subclinical atherosclerosis in RA, with an emphasis on potential application of novel modalities, high-resolution magnetic resonance imaging and positron em...
