Quantitative analysis has been applied extensively to image processing and interpretation in
nuclear cardiology to improve disease diagnosis and risk stratification. This is Part 2 of a two …

Patient motion during dynamic PET imaging can induce errors in myocardial blood flow
(MBF) estimation. Motion correction for dynamic cardiac PET is challenging because the …

Background 18 F-Flurpiridaz is a promising investigational radiotracer for PET myocardial
perfusion imaging with favorable properties for quantification of myocardial blood flow …

Background PET myocardial flow reserve (MFR) has established diagnostic and prognostic
value. Technological advances have now enabled SPECT MFR quantification. We …

Background Repositioning of the heart during myocardial perfusion imaging (MPI) using
Rubidium-82 (Rb-82) PET may occur when using regadenoson. Our aim was to determine …

Background Patient motion can lead to misalignment of left ventricular (LV) volumes-of-
interest (VOIs) and subsequently inaccurate quantification of myocardial blood flow (MBF) …

For dynamic cardiac PET of quantifying myocardial blood flow (MBF), patient motion is a
major factor that affects the ROI definition and absolute quantification accuracy. In a recent …

Purpose We sought to evaluate the diagnostic performance for coronary artery disease
(CAD) of myocardial blood flow (MBF) quantification with 18F-flurpiridaz PET using motion …

Motion correction (MC) affects myocardial blood flow (MBF) measurements in 82Rb PET
myocardial perfusion imaging (MPI); however, frame-by-frame manual MC of dynamic …

Purpose Patient body motion during a cardiac positron emission tomography (PET) scan
can severely degrade image quality. We propose and evaluate a novel method to detect …
