Quantitative Positron Emission Tomography for Estimation of Absolute Myocardial Blood Flow
<p>Myocardial perfusion imaging (MPI) with positron emission tomography (PET) is an emerging clinical tool for diagnosis and characterization of ischemic heart disease. The increasing use of PET introduces an opportunity, as it is capable of providing quantitative images that can be analyzed with …

Exercise in Ponies: A Study of Myocardial Blood Flow, Coronary Vasodilator Reserve, Regional Distribution of Cardiac Output and Effects of Heart Rate on Coronary Flow
Transmural distribution of myocardial blood flow (MBF, 15 (mu)m diameter radionuclide labeled microspheres) was studied in 11 adult healthy ponies at rest {heart rate (HR) = 56 (+OR-) 4 beats.min('-1)}, during moderate (HR = 154 (+OR-) 3 beats.min('-1)) and severe (32 km.hr('-1), HR = 225 (+OR-) 7 …

Quantification of cardiac magnetic resonance imaging perfusion in the clinical setting at 3T
… coronary artery disease (CAD) which can impair myocardial blood flow and may result in myocardial infarction. Mathematical modelling of cardiac DCE-MRI data can provide quantitative assessment of myocardial blood flow. Quantitative assessment of myocardial blood flow may have merit in further …

Motion Detection in Dynamic Cardiac Positron Emission Tomography Images
… PET is being increasingly utilized to quantify myocardial blood flow, leading to improved diagnostic and prognostic value for the management of coronary artery disease. MBF quantification assumes constant positioning of anatomical structures throughout image acquisition. This assumption is …

Hydrodynamic considerations of coronary blood flow with and without stenosis
… to study the effects of the stenosis on the blood flow, and thus to determine its influence on myocardial perfusion. In summary, this thesis is concerned with the effects of the stenosis on left coronary blood flow. To determine these effects it has been necessary in a first step to …

Epidural analgesia for coronary artery bypass graft surgery
… may be cardioprotective through the promotion of myocardial blood flow to areas at-risk and subsequent early, small clinical studies suggesting that TEA was feasible, and possibly also beneficial in CABG surgery [Joachimsson et. al, 1989; Liem (1-3) et. al, 1992; Stenseth et. al, 1994]. Despite …
