Papillary muscle ischemia and myocardial blood flow on N13-ammonia positron emission tomography myocardial perfusion imaging

Positron 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 ...

Positron emission tomography and myocardial imaging.

Quantification of Regional Myocardial Blood Flow Using '3N-Ammonia and Reoriented Dynamic Positron Emission Tomographic Imaging

Background. Regional myocardial blood flow has been quantified using transaxial positron emission tomographic (PET) imaging and tracer kinetic modeling. However, the use of transaxial images limits the accuracy of regional partial volume corrections and the localization of the quantified regional flow values. The purpose of the present study was to overcome both problems by calculating regional...
