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.

Physicians urge Trump administration to exempt radiopharmaceuticals from tariffs

The American Society of Nuclear Cardiology wants the feds to protect these vital imaging products from tariffs, highlighting barriers to U.S. production. 

Tariffs will have a significant impact on the nuclear imaging supply chain in the US

"Domestic radiopharmaceutical suppliers, who receive isotopes from abroad, would be impacted by price changes and uncertainty caused by additional tariffs,” SNMMI President Cathy Cutler, PhD, wrote in a letter to the U.S. Department of Commerce this week.

Tariffs not enough to make Siemens Healthineers move production or raise prices—yet

The imaging manufacturer expects to spend between $227 million and $340 million on tariff mitigation efforts, leaders said Wednesday.

Around the web

News of an incident is a stark reminder that healthcare workers and patients aren’t the only ones who need to be aware around MRI suites.

The ACR hopes these changes, including the addition of diagnostic performance feedback, will help reduce the number of patients with incidental nodules lost to follow-up each year.

And it can do so with almost 100% accuracy as a first reader, according to a new large-scale analysis.
