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.

PET scans offer insight into how ketamine affects depression
Thanks to a newly developed radiotracer and PET imaging, experts believe they may have unearthed new insights on the drug's impact.
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.
Side effect of popular Alzheimer's treatment may actually be a good sign, new PET findings suggest
Amyloid-related imaging abnormality edema is a known side effect of anti-amyloid monoclonal antibody treatments, such as Leqembi and donanemab Kisunla.
Drugmaker expands manufacturing of popular prostate PET imaging agent

FDA clears new PET/MRI combo system from Siemens Healthineers
The Biograph One is the company's second-generation PET/MRI combo scanner—its first in 14 years.

Some PET exams may be overutilized in oncology

In 2020 alone, there were more than 2 million 18F-FDG PET/CT scans conducted in the United States.

PSMA-PET imaging not the most cost-effective option for many prostate cancer patients

The exam effectively helps providers manage patients’ treatment options, but for some, the costs associated with those treatments may negate the value of its findings.

PET study targets inflammation to predict AMI recovery

Inflammation-targeting PET method predicts recovery after heart attack

Targeting CXCR4 during PET scans could help providers gain vital information regarding patients' potential to fully recover from myocardial infarction.

Nuclear cardiology is entering a new era—one that goes well beyond the traditional focus on myocardial perfusion imaging. According to Marcelo Di Carli, MD, editor-in-chief of the Journal of Nuclear Cardiology and chief of the Division of Nuclear Medicine at Brigham and Women’s Hospital, the field is rapidly expanding into diagnosing and monitoring complex cardiac diseases such as amyloidosis, sarcoidosis, myocarditis, and cardiac infections.

Nuclear cardiology expands beyond perfusion imaging as it enters a new era

Beyond amyloidosis, nuclear cardiology is also increasingly used to image inflammation and infection in the myocardium, especially in diseases such as cardiac sarcoidosis and myocarditis.

Positron emission tomography (PET) nuclear imaging has seen rapid expansion in cardiology and oncology due to its improve accuracy over SPECT and its ability to expand into new areas of cardiovascular imaging. A new review in the American Heart Association journal Stroke outlines another possible use of PET to assess carotid artery atherosclerosis for stroke prevention.

PET holds promise for carotid plaque assessments

PET has already gained significant momentum in recent years. Now, researchers are pointing to another possible use for the popular imaging modality: assessing carotid artery atherosclerosis.

Imaging offers insight into impact of new Alzheimer's treatment from Eli Lilly

Emerging research provides further evidence that amyloid-removal treatment for Alzheimer’s effectively slows cognitive decline.

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.
