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.

Global shortage of nuclear imaging isotopes may be over
The nuclear imaging isotope shortage of molybdenum-99 may be over now that the sidelined reactor is restarting. ASNC's president says PET and new SPECT technologies helped cardiac imaging labs better weather the storm.
Researchers receive grant worth millions to develop portable PET scanner
Experts are hopeful that the portable scanner could improve access to neuroimaging used in the diagnosis and monitoring of Alzheimer's disease.
Why is the US still dependent on foreign medical isotope production?
The U.S currently does not have any large-scale commercial production of the isotope Mo-99 used for nuclear imaging. It is critical to more 40,000 nuclear imaging exams each day, representing about 80% of all diagnostic molecular imaging procedures.
Downed high-flux reactor could restart sooner than anticipated
The announcement will come as welcome news, as nuclear medicine departments in numerous regions have been grappling with shortages of Mo-99 and Tc-99m.
Some nuc med departments are already feeling the strain of the isotope shortage
"This can't drag on. Patients needing cancer treatment can’t wait two months for an accurate diagnosis.”

ASNC monitoring potential Mo-99 supply shortages due to COVID-19

The president of the American Society of Nuclear Cardiology said there are no shortfalls reported at this time, but the organization is keeping an eye on the situation as more countries implement travel bans.

ASNC publishes new amyloidosis imaging guidelines

“We anticipate that these expert multisocietal consensus recommendations on multimodality imaging in cardiac amyloidosis will standardize the diagnosis and improve the management of this highly morbid and underdiagnosed disease," wrote authors of the new guidelines published in the Journal of Nuclear Cardiology.
