Development and evolution of nuclear cardiology and cardiac PET in Canada.

Gated radionuclide angiography and myocardial perfusion imaging were developed in the United States and Europe in the 1970's and soon adopted in Canadian centers. Much of the early development of nuclear cardiology in Canada was in Toronto, Ontario and was quickly followed by new programs across the country. Clinical research in Canada contributed to the further development of nuclear cardiology and cardiac PET. The Canadian Nuclear Cardiology Society (CNCS) was formed in 1995 and became the Canadian Society of Cardiovascular Nuclear and CT Imaging (CNCT) in 2014. The CNCS had a major role in education and advocacy for cardiovascular nuclear medicine testing. The CNCS established the Dr Robert Burns Lecture and CNCT named the Canadian Society of Cardiovascular Nuclear and CT Imaging Annual Achievement Award for Dr Michael Freeman in memoriam of these two outstanding Canadian leaders in nuclear cardiology. The future of nuclear cardiology in Canada is exciting with the expanding use of SPECT imaging to include Tc-99m-pyrophosphate for diagnosis of transthyretin cardiac amyloidosis and the ongoing introduction of cardiac PET imaging.

Pulmonary Circulation Discovery Before Ibn Nafis-Ancient Persian and Greek Theories: A Narrative Review.

Importance: The recognition of the pulmonary circulation is a complex evolution in medical history and draws on theories across eras and cultures. Observations: This narrative review summarizes evidence suggesting that the recognition of pulmonary circulation is older than the time of Ibn Nafis. The theory of pulmonary circulation originated in ancient Persia (ad 224-637), was overshadowed by Greek theory from the 11th century, and reestablished by Ibn Nafis in the 13th century. Conclusions and Relevance: The findings of this review may help contextualize the story of the discovery of pulmonary circulation in ancient Persian and Greek theories before Ibn Nafis.
