Nuclear Medicine

Nuclear medicine (also called molecular imaging) includes positron emission computed tomography (PET) and single photon emission computed tomography (SPECT) imaging. Nuclear imaging is achieved by injecting small amounts of radioactive material (radiopharmaceuticals) into patients before or during their scan. These can use sugars or chemical traits to bond to specific cells. The radioactive material is taken up by cells that consume the sugars. The radiation emitted from inside the body is detected by photon detectors outside the body. Computers take the data to assemble images of the radiation emissions. Nuclear images may appear fuzzy or ghostly rather than the sharper resolution from MRI and CT.  But, it provides metabolic information at a cellular level, showing if there are defects in the function of the heart, areas of very high metabolic activity associated with cancer cells, or areas of inflammation, data not available from other modalities. These noninvasive imaging exams are used to diagnose cancer, heart disease, Alzheimer’s and Parkinson’s disease, bone disorders and other disorders.

Medicare drops AUC requirement for advanced imaging, ASNC celebrates

"This was an unneeded burden, which was solely adding to the administrative hassles of medicine," said American Society of Nuclear Cardiology President Larry Phillips.

Video interview with Tim Bateman, MD, co-director, cardiovascular radiologic imaging program, Saint Luke's Mid America Heart Institute and an American Society of Nuclear Cardiology (ASNC) past-president, explaining the role of SPECT into the future as PET becomes more popular. A new look at PET vs SPECT.

SPECT still has an important role to play in nuclear cardiology

"I see, at least for the next decade, this being a SPECT and PET world, not one or the other," explained Tim Bateman, MD.

New imaging protocols proposed to curb rise of cardiovascular infections

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

American Society of Nuclear Cardiology (ASNC) 2024 President Lawrence Phillips, MD, FASNC, director of nuclear cardiology and medical director for outpatient cardiology at NYU Langone Health, explains ASNC’s advocacy efforts for Medicare payments and reform.

ASNC president advocates for Medicare reimbursement reform

Lawrence Phillips, MD, president of the American Society of Nuclear Cardiology, said that U.S. physicians are growing more and more frustrated by Medicare policies.

ASNC president pushes to modernize nuclear cardiology, expand the specialty's reach

ASNC President Lawrence Phillips, MD, wants to see nuclear cardiologists modernize their labs and embrace new strategies for the evaluation of amyloidosis, sarcoidosis and inflammation.

Jamie Bourque, MD, medical director of the nuclear cardiology and stress laboratory, and medical director of the echocardiography lab, at the University of Virginia, discusses a new multimodality consensus statement for imaging cardiac amyloidosis. This area has rapidly expanded over the past couple years now that there are drugs to treat the condition.

New ASNC quality metrics will support standardization of imaging for cardiac amyloidosis

Interest in cardiac amyloidosis has been on the rise in recent years. Jamie Bourque, MD, talked to Cardiovascular Business about an upcoming consensus statement focused on using cardiac imaging to evaluate patients for signs of this serious condition. 

Rob deKemp, PhD, FASNC, University of Ottawa, Canada, explains new nuclear cardiac imaging dose lowering techniques for PET and SPECT.

How to achieve much lower radiation doses in cardiac nuclear imaging

The radiation doses associated with CT have decreased significantly, leaving nuclear cardiology as the modality with the highest doses in all of cardiac imaging. Rob deKemp, PhD, talked to us about some of the many ways imagers can work to address this issue.

The expanding scope of FDG-PET in nuclear cardiac imaging

Jamie Bourque, MD, spoke to Cardiovascular Business about the growing number of ways FDG-PET scans are being used in cardiology. This includes evaluating inflammation, tracking EP device infections and much more.
