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.

Rural patients less likely to undergo PET imaging for prostate cancer
Experts suggest possible remedies to this disparity, including mobile PET units or establishing hub-and-spoke care models.
Post-ablation PET imaging may not be cost-effective in patients with liver metastases
Although most radiology organizations agree that [18F]FDG PET/CT can provide valuable information in these patients post-treatment, their recommendations differ on its use.
Mayo Clinic develops AI capable of substantially improving dementia diagnoses
With the software's help, readers are up to three times more accurate and interpretations are nearly twice as fast.
FDA approves expanded use of PET imaging agent
The product's updated indications include quantification and long-term monitoring of amyloid plaques on imaging.
'Powerful' new PET agent improves the diagnosis of triple-negative breast cancer
The agent “exhibits powerful tumor delineation” in challenging cases of determining cancer subtypes, and could potentially lead to more personalized, effective treatment strategies.
