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.
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.

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.

SNMMI: Scanning for cardiac amyloid could help predict heart attacks

While amyloid imaging is typically discussed with regard to diagnosing Alzheimer’s disease, a team of French researchers, presenting at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2015 annual meeting, have found that amyloid scans of the heart can predict major cardiac events.

PET technique visualizes amyloid deposits in heart

PET with 11C-PIB provides a noninvasive method for visualizing amyloid deposits in the heart, according to a study published in the February issue of the Journal of Nuclear Medicine. The researchers suggest that 11C-PIB eventually may be used in the clinical setting as both a diagnostic tool and a treatment follow-up method.

ASNC Releases Dose-Reduction Guidelines for Nuclear Cardiology

Technological improvements in image acquisition and software processing in nuclear cardiology should allow physicians to shave patient imaging times dramatically or cut radiation doses fourfold, according to a new preferred practice statement from the American Society of Nuclear Cardiology (ASNC).

What does radiology have to do with climate change?

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
