Quantification of myocardial perfusion and myocardial perfusion reserve by positron emission tomography and cardiovascular magnetic resonance imaging.
Physiology and pathophysiology of myocardial perfusion regulation and of myocardial perfusion reserve. Because of the high energy demands of myocardial contraction, the heart is critically dependent on oxidative metabolism, and insufficient myocardial oxygen delivery (i.e., ischemia) results almost instantaneously in contractile and electrical dysfunction. Because myocardial oxygen extraction i...
متن کاملMyocardial perfusion SPECT: Perfusion quantification
Different software tools for quantification of myocardial perfusion SPECT (MPS) studies are routinely used. Several perfusion parameters can be computed automatically. Interpretation of the MPS should start with visual inspection of the rotating planar images, visual analysis of reconstructed SPECT slices and then quantitative analysis to confirm the visual impression. Quantification should be...
متن کاملQuantification of Absolute Myocardial Perfusion With Dynamic Positron Emission Tomography
Positron emission tomography (PET) was applied to the measurement of myocardial perfusion using the perfusion tracer 13N-labeled ammonia. 13N ammonia was delivered intravenously to 13 healthy volunteers both at rest and during supine bicycle exercise. Dynamic PET imaging was obtained in three cross-sectional planes for 10 minutes commencing with each injection. The left ventricle was divided in...
متن کاملQuantification of myocardial perfusion by cardiovascular magnetic resonance
The potential of contrast-enhanced cardiovascular magnetic resonance (CMR) for a quantitative assessment of myocardial perfusion has been explored for more than a decade now, with encouraging results from comparisons with accepted "gold standards", such as microspheres used in the physiology laboratory. This has generated an increasing interest in the requirements and methodological approaches ...
متن کاملPositron emission tomography myocardial perfusion and glucose metabolism imaging.
Cardiac positron emission tomography (PET) imaging is a well-validated, reimbursable means to assess myocardial perfusion, left ventricular (LV) function, and viability. Presently, there is a proliferation of PET and PET/computed tomography (CT) instrumentation as well as an increase in educational programs that specifically address PET and PET/CT imaging. Technologists performing PET scans as ...
