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.

Ozempic and similar weight loss drugs may impact medical imaging results
GLP-1 receptor agonists alter glucose metabolism and the movement of food through the digestive system and can lead to unique uptake patterns on FDG PET-CT.
An imaging AI 'epilepsy detective' could help cure treatment-resistant seizures
The tool can identify small focal cortical dysplasia on imaging that is typically missed by radiologists, bottom-of-sulcus dysplasia in particular.
COVID-induced neuroinflammation can last 2 years or longer, according to new PET data
These findings are important to consider with regard to patients’ long-term health, as chronic inflammation has been implicated in cognitive decline.
Key trends in nuclear cardiology take center stage at ASNC 2025
Wael Jaber, MD, chair of the 2025 American Society of Nuclear Cardiology annual meeting, shared some key takeaways from the conference. “This is no longer just about imaging for coronary disease," he explained. "Nuclear cardiology now helps guide therapy across a wide range of conditions."
Compact multifunctional PET scanner receives clearance in the US
The system was built with patients in mind, and its compact design has the potential to expand access to the modality where it may have previously been lacking.

A 'clear lack of adherence' in imaging guidelines is impacting lung cancer survival rates

A study published in the January issue of the Journal of Nuclear Medicine reveals that nearly half of Medicare patients with NSCLC in the United States do not complete recommended FDG PET/CT scans prior to treatment.

‘Revolutionary’ new CT scans identify the most common cause of high blood pressure

Primary aldosteronism (PA) is one the single most common causes of hypertension, but identifying patients with PA—and knowing which ones may benefit from a surgical treatment—can be quite challenging.

New type of PET/CT scan could change how hypertension is diagnosed and treated

The 10-minute scan can “light up” aldosterone-producing nodules in the adrenal glands following an injection of metomidate—a radioactive dye that binds specifically to aldosterone-producing nodules.

ASNC 2023 president calls for nuclear cardiology to embrace new technology

American Society of Nuclear Cardiology (ASNC) 2023 President Mouaz H. Al-Mallah, MD, said the subspecialty needs to up its game with new technology.

Regularly eating avocados is associated with a reduced risk of cardiovascular disease, according to a new study.

Why clinicians should know if patients are on the keto diet before undergoing PET imaging

Patients adhering to a ketogenic diet can show reduced cerebral 18F-FDG uptake on PET imaging, study shows.

CMS cites 'newly published evidence' in postponement of PET coverage decision

Prior to the Dec. 15 announcement, CMS had released a different statement in June informing the public that they were reconsidering the amount of PET scans that Alzheimer’s patients undergoing monoclonal antibody treatment can receive.

New radiotracer IDs numerous cancers likely to respond to targeted therapy

The radiotracer, 68Ga-PentixaFor, can be used for detecting C-X-C motif chemokine receptor 4 (CXCR4), which plays a significant role in cancer progression.

Cognitive decline not far behind amyloid and tau PET-positive scans, even for the asymptomatic

Common markers of Alzheimer's disease visualized on PET scans of asymptomatic patients might foreshadow the onset of symptoms in the years following their initial discovery.
