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.

An example of a positive amyloid plaque PET nuclear brain scan. these tests can help identify Alzheimer's patients earlier so they can be prescribed drugs to treat the condition.

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.

FAPI PET/CT findings linked with risk of sudden cardiac death

Experts involved in the research suggested that these findings indicate a potential role for FAPI PET/CT imaging in detecting changes in myocardial fibrosis, noting that it could be more sensitive to earlier changes than standard cardiac MRI.

Automated AI-generated measurements combined with annotated CT images can improve treatment planning and help referring physicians and patients better understand their disease, explained Sarah Jane Rinehart, MD, director of cardiac imaging with Charleston Area Medical Center.

Two advanced algorithms—one for CAC scores and another for segmenting cardiac chamber volumes—outperformed radiologists when assessing low-dose chest CT scans. 

"Gen AI can help tackle repetitive tasks and provide insights into massive datasets, saving valuable time," Thomas Kurian, CEO of Google Cloud, said Tuesday.
