Positron Emission Tomography. Usefulness in assessing myocardial viability.

Positron emission tomography for the assessment of myocardial viability.

The detection of viable myocardium or ischemically injured myocardium with a reversible impairment of contractile function remains clinically important but challenging. Detection of reversible dysfunction and distinction from irreversible tissue injury by positron emission tomography is based on identification of preserved or even enhanced glucose metabolism with F-18 2-fluoro 2-deoxyglucose. R...

A Comparison of Thallium-201 Spect and F-18 Deoxyglucose Positron Emission Tomography in Assessing Myocardial Viability

Assessment of myocardial viability 1>rior to revascularization procedures is an important clinical consideration for improved functional recovery of regional left ventricular dysfunction. In chronic coronary artery disease, impaired left ventricular function , at least in part, is due to ischemic or hibernating myocardium rather than just myocardial fibrosis. Functional recovery of the left ven...

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...

Usefulness of positron emission tomography in clinical oncology

Although positron emission tomography (PET) is expensive in terms of absolute dollars per exam ($2000 reimbursement by Medicare), its superior accuracy for multiple oncologic indications makes it a promising tool. Oncologists can improve treatment selection when they have access to the most accurate staging data. In addition, the more accurate noninvasive data obtained with PET may provide cons...
