Molecular Imaging

Molecular imaging (also called nuclear medicine or nuclear imaging) can image the function of cells inside the body at the molecular level. This includes the imaging modalities of positron emission computed tomography (PET) and single photon emission computed tomography (SPECT) imaging. How does PET and SPECT imaging work? Small amounts of radioactive material (radiopharmaceuticals) injected into a patient. 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.

Pharmacist pleads guilty to 'adulterating' radiopharmaceuticals

According to the DOJ, the pharmacist and those working under him “would ‘fractionate’ or ‘split’ the active ingredient of Technescan MAG3, without ensuring the pieces were equal in size, purity or strength.”

Q4 and full-year 2022 results in for GE HealthCare

GE HealthCare has some favorable tailwinds at its back as it proceeds into its first year unattached to a certain venerable parent corporation. 

FAPI PET/CT shows promise as a better radiotracer for cancer than 18F-FDG. It also can be used for detection of infection and inflammation.

VIDEO: 6 key advances in molecular imaging technology for PET and SPECT

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.
