Incremental diagnostic value of regional myocardial blood flow quantification over relative perfusion imaging with generator-produced rubidium-82 PET.
BACKGROUND Myocardial blood flow (MBF) can be measured with positron emission tomography (PET) and its quantification should provide diagnostic information beyond that obtained through standard visual analysis. However, this possibility has not been fully studied with PET and generator-produced rubidium-82 (⁸²Rb). We evaluated regional MBF in segments with and without ischemia using ⁸²Rb PET in...
متن کاملQuantitative myocardial blood flow with Rubidium-82 PET: a clinical perspective.
Positron emission tomography (PET) allows assessment of myocardial blood flow in absolute terms (ml/min/g). Quantification of myocardial blood flow (MBF) and myocardial flow reserve (MFR) extend the scope of conventional semi-quantitative myocardial perfusion imaging (MPI): e.g. in 1) identification of the extent of a multivessel coronary artery disease (CAD) burden, 2) patients with balanced 3...
متن کاملAdded prognostic value of myocardial blood flow quantitation in rubidium-82 positron emission tomography imaging.
AIMS We studied the respective added value of the quantitative myocardial blood flow (MBF) and the myocardial flow reserve (MFR) as assessed with (82)Rb positron emission tomography (PET)/CT in predicting major adverse cardiovascular events (MACEs) in patients with suspected myocardial ischaemia. METHODS AND RESULTS Myocardial perfusion images were analysed semi-quantitatively (SDS, summed di...
متن کاملPrecision and accuracy of clinical quantification of myocardial blood flow by dynamic PET: A technical perspective.
A number of exciting advances in PET/CT technology and improvements in methodology have recently converged to enhance the feasibility of routine clinical quantification of myocardial blood flow and flow reserve. Recent promising clinical results are pointing toward an important role for myocardial blood flow in the care of patients. Absolute blood flow quantification can be a powerful clinical ...
