PET/CT

Positron emission tomography/computed tomography is a hybrid nuclear medicine imaging technique that helps radiologists spot abnormal metabolic activity. PET/CT is commonly used to diagnose cancers, heart diseases and certain brain disorders, among other conditions.

Combining PET and MRI data helps distinguish between LATE and Alzheimer's

Combining PET and MRI data may be key to differentiating new type of dementia

Limbic-predominant age-related TDP-43 encephalopathy, also known as LATE, was recently recognized as a type of dementia that occurs in older adults. It typically presents as memory-related cognitive decline.

ASNC says PET is now the preferred nuclear imaging test for CAD

Which imaging modality is better for evaluating heart patients, PET or SPECT? After years of discussions and debates, the American Society of Nuclear Cardiology is now ready to point to PET as the No. 1 choice. “There are no clinical scenarios or patient subgroups where cardiac PET with myocardial blood flow should be excluded," the group wrote.

FAPI PET shows promise to make a big impact in cardiovascular imaging

More and more imaging researchers are starting to examine the potential of using fibroblast activation protein inhibitors (FAPI) to manage patients with suspected cardiovascular disease.

Software glitch prompts FDA recall of popular PET systems

The recall was issued due to the potential for the systems to produce artifacts during PET exams.
