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.

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.
Bayer expands into molecular imaging with cardiac amyloidosis tracer acquisitions
Bayer is acquiring two cardiac amyloidosis radiotracers from Attralus, one for PET and one for SPECT. The SPECT tracer is also a theranostic agent to both image and treat amyloidosis.
Key trends in medical imaging systems at RSNA 2025
Sarah-Jane James, imaging market analyst for Signify Research, discusses key trends in the specialty that she saw at the Radiological Society of North America's annual meeting.

Researchers track dopamine receptors to study its impact on cognitive function.

New PET study offers insight into how dopamine drives executive function

These findings could help guide the development of new treatments for psychiatric and neurological disorders.

Bracco updates HeartSee coronary flow capacity software with new diagnostic features

Clinicians have been using HeartSee to diagnose and treat coronary artery disease since the technology first debuted back in 2018. These latest updates, set to roll out to existing users, are designed to improve diagnostic performance and user access.

New PET method combines antibody with radioactive isotope to improve lung cancer detection

By giving providers greater insight into a tumor’s molecular footprint, the method could also reduce the need for invasive biopsies.

ALS drug repurposed for PET imaging

Researchers radiolabeled the drug so that they could follow its movement and breakdown in the body to help visualize areas of oxidative stress.

New radiotracer has 'incredible potential' to improve management of spinal cord injuries

Experts hope the information gained from their research could help providers better determine whether patients will regain mobility after sustaining an injury.

Mexico, not China, is biggest tariff concern among radiology vendors

If 25% tariffs go into effect, it could have a big impact on the cost of medical imaging and radiotherapy systems, with many manufacturing facilities in Mexico.

Experts say one radiotracer outperforms all others when it comes to detecting prostate cancer

There are numerous radiotracers specifically designed to identify prostate cancer, but experts say one may be superior to the others at both the patient and lesion level.

New radiotracers outperform FDA-approved agent for detection of tau tangles.

Radiotracers on FDA’s fast track exceed performance of already approved tau-detecting agent

If approved, the two agents could offer providers greater insight into the process of patients’ neurodegeneration.
