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.

Sean Fain, PhD, vice chair of radiology and research and a professor of radiology, Division of Cardiovascular and Thoracic Imaging, University of Iowa, discusses how long-COVID lung damage can be tracked using xenon (Xe) gas magnetic resonance imaging (MRI) and quantitative computed tomography (CT). He spoke to Health Imaging at RSNA 2022.

why are T. Rex arms so short?

Experts hope CT can help unlock age-old question: Why were T. Rex arms so short?

Experts are hoping that, by imaging the dinosaur’s shoulder girdle and forelimb, they can create a digital model that could help in determining a T. Rex arm’s range of motion and strength.

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.

This is your brain on smartphones: MRI study reveals altered network strength in brains of smartphone 'addicts'

The study, which was published in Brain and Behavior, found that individuals who used their smartphone excessively displayed different strengths in the prefrontal and parietal neural network.

Patient with severe, lung damage from COVID. Images in a 54-year-old man with COVID-19–related acute respiratory distress syndrome and subsequent fibrosis. (A) Axial CT 2 weeks after admission shows diffuse ground-glass opacity (GGO) with reticular abnormality and traction bronchiectasis in right middle lobe, indicating organizing phase of lung injury. (B) Axial CT 6 months after admission shows decreased GGO but extensive traction bronchiectasis and architectural distortion, suggesting fibrosis. RSNA

Lung scarring occurs in up to 11% of patients recovered from COVID, regardless of infection severity

Researchers cannot yet determine whether these changes will progress or resolve in the long term.

If President Trump initiates a 25% tariff against pharmaceuticals imported from Ireland, it might impact the price for X-ray iodine contrast agents in the U.S. 

This two-year analysis of the FISH&CHIPS study found that using advanced AI from Heartflow to evaluate cardiac CT is safe, effective and limits the use of unnecessary follow-up tests.

The imaging manufacturer expects to spend between $227 million and $340 million on tariff mitigation efforts, leaders said Wednesday.
