The Society of Nuclear Medicine and Molecular Imaging's (SNMMI) Cardiovascular Council and the American Society of Nuclear Cardiology (ASNC) have issued the joint position paper, Clinical Quantification of Myocardial Blood Flow Using PET, which was jointly published in the Journal of Nuclear Cardiology and The Journal of Nuclear Medicine.
Radionuclide myocardial perfusion imaging (MPI) is among the most commonly performed diagnostic tests in cardiology. Positron emission tomography (PET) can quantify global and regional myocardial blood flow, assess regional perfusion abnormalities with relative MPI, and assess function abnormalities and chamber dimensions. Quantification of myocardial blood flow requires accurate measurement of the total tracer activity transported by the arterial blood and delivered to the myocardium over time.
This position statement consolidates and updates technical considerations for clinical quantification of myocardial blood flow and myocardial flow reserve, and it summarizes and updates the scientific basis for their clinical application.
"Quantification of myocardial blood flow is the next great leap in nuclear cardiology, and this document summarizes the data supporting its use and offers guidance to those who are planning to make these measurements in practice," explains Venkatesh L. Murthy, MD, PhD, vice president-elect of SNMMI's Cardiovascular Council and a lead author of the position statement.
Prem Soman, MD, PhD, FACC, FASNC, president of ASNC and co-author of the document, points out, "This is a comprehensive document which offers many useful insights into the theory and practice of PET myocardial perfusion imaging."
The position paper states, "Quantification of myocardial blood flow and myocardial flow reserve represents a substantial advance for diagnostic and prognostic evaluation of suspected or established coronary artery disease. These methods are at the cusp of translation to clinical practice." It notes, however, that further efforts are necessary to standardize measures across laboratories, radiotracers, equipment, and software--pointing out, "Most critically, data are needed supporting improved clinical outcomes when treatment selection is based on these measures."

ABOUT THE SOCIETY OF NUCLEAR MEDICINE AND MOLECULAR IMAGING
The Society of Nuclear Medicine and Molecular Imaging (SNMMI) is an international scientific and medical organization dedicated to raising awareness about nuclear medicine and molecular imaging, vital elements of precision medicine that allow diagnosis and treatment to be tailored to individual patients in order to achieve the best possible outcomes.
SNMMI's more than 15,000 members set the standard for molecular imaging and nuclear medicine practice by creating guidelines, sharing information through journals and meetings and leading advocacy on key issues that affect molecular imaging and therapy research and practice. SNMMI's Cardiovascular Council works to ensure and enhance the quality and clinical utility of the use of cardiovascular nuclear medicine studies in patient care.

ABOUT THE AMERICAN SOCIETY OF NUCLEAR CARDIOLOGY
ASNC is the recognized leader in quality, education, advocacy and standards in cardiovascular imaging, with more than 4,200 members worldwide. 2018 marks its 25th year anniversary as the only society dedicated solely to advocacy issues that impact the field of nuclear cardiology and is working with success to influence regulations to fight onerous private health plan policies - adverting reimbursement declines and fighting for improved payment and coverage. ASNC is dedicated to continuous quality improvement, education and patient-centered imaging, illustrating the ongoing commitment as a leader in the field of nuclear imaging and improving patient outcomes. ASNC establishes standards for excellence in cardiovascular imaging through the development of clinical guidelines, professional education, advocacy and research development. ASNC's members are comprised of cardiologists, radiologists, physicians, scientists, technologists, imaging specialists and other professionals committed to the science and practice of nuclear cardiology.
