Study updates dose estimates for rubidium-82 cardiac PET
By Wayne Forrest
Rubidium-82 is increasingly being used for cardiac PET imaging, but radiation dose estimates for the exams are based on old -- and conflicting -- data. Researchers from Johns Hopkins University offer updated dose estimates for rubidium-82 procedures in a study published in the October issue of the Journal of Nuclear Medicine.

Contrast MRI evaluates myocardial viability in patients with ICDs
By Wayne Forrest
Researchers from the University of Maryland in Baltimore have found that contrast-enhanced MRI and FDG-PET can help in the accurate differentiation between viable and nonviable myocardium in patients with implantable cardioverter-defibrillator (ICD) devices undergoing ventricular tachycardia ablations.
