چکیده
t t i t a i f f c Sdringola et al. (1) in this issue of iJACC address an issue of considerable importance, both for clinical and for research applications concerning positron emission tomography (PET) measurements of absolute myocardial blood flow (MBF). In brief, they attempted what at first blush seems a simple and obvious task; namely to define “normal” values of MBF (82Rb method) at rest and with pharmacological stress (dipyridamole) and coronary flow reserve (CFR) ratio (MBFdip/MBFrest). They also

Repeatability of rest and hyperemic myocardial blood flow measurements with 82Rb dynamic PET.
UNLABELLED The repeatability of rest and hyperemic myocardial blood flow (MBF) measurements using 82Rb PET has not been evaluated. The aim of this study was to investigate the short-term repeatability of such measurements. METHODS Fifteen healthy volunteers underwent rest and pharmacologic stress 82Rb PET, repeated 60 min apart. RESULTS There was no significant difference in repeated rest M...
متن کاملImpact of unexpected factors on quantitative myocardial perfusion and coronary flow reserve in young, asymptomatic volunteers.
OBJECTIVES We sought to quantify ranges of normal myocardial perfusion and flow reserve in young, asymptomatic volunteers after systematic historical and laboratory screening for unexpected factors affecting coronary flow. BACKGROUND Noninvasive cardiac positron emission tomography (PET) quantifies absolute flow and coronary flow reserve (CFR), thereby defining physiological severity of coron...
متن کاملEffect of Post-Reconstruction Gaussian Filtering on Image Quality and Myocardial Blood Flow Measurement with N-13 Ammonia PET
Objective(s): In order to evaluate the effect of post-reconstruction Gaussian filtering on image quality and myocardial blood flow (MBF) measurement by dynamic N-13 ammonia positron emission tomography (PET), we compared various reconstruction and filtering methods with image characteristics. Methods: Dynamic PET images of three patients with coronary artery disease (male-female ratio of 2:1; a...
متن کاملRelationship between regional myocardial oxygenation and perfusion in patients with coronary artery disease: insights from cardiovascular magnetic resonance and positron emission tomography.
BACKGROUND It is recognized that the interplay between myocardial ischemia, perfusion, and oxygenation in the setting of coronary artery disease (CAD) is complex and that myocardial oxygenation and perfusion may become dissociated. Blood oxygen level-dependent (BOLD) cardiovascular magnetic resonance (CMR) has the potential to noninvasively measure myocardial oxygenation, whereas positron emiss...
متن کاملQuantitative evaluation of myocardial blood flow and ejection fraction with a single dose of (13)NH(3) and Gated PET.
UNLABELLED To evaluate myocardial blood flow (MBF) and cardiac function with a single dose of (13)NH(3), electrocardiographically (ECG) gated PET acquisition was performed after a dynamic PET scan was obtained. Gated blood-pool (GBP) imaging with C(15)O PET was also performed to compare the left ventricular ejection fraction (LVEF) obtained using the 2 methods. METHODS Six healthy volunteers ...
