Medical Imaging

Physicians utilize medical imaging to see inside the body to diagnose and treat patients. This includes computed tomography (CT), magnetic resonance imaging (MRI), X-ray, ultrasound, fluoroscopy, angiography,  and the nuclear imaging modalities of PET and SPECT.

Some soccer players are at risk of brain damage similar to CTE

American football isn’t the only contact sport that has medical experts concerned with the brain health of athletes. New evidence suggests certain soccer players may be at heightened risk of long-term brain abnormalities, too.

GBCA dose reduced by up to 80% with help from deep learning-based image reconstruction

Although GBCAs are largely considered safe, there are concerns about how gadolinium retention could affect patients who require repeated imaging.

Concussions may slow 'background' brain activity in athletes, new imaging shows

New research into post-concussion brain health suggests that the impact of head trauma may be more far-reaching than previously believed. 

Experts publish updated guidance on nuclear imaging for fevers of unknown origin

Fevers of unknown origin account for around 2% of hospitalizations and can present significant diagnostic challenges for providers.

Vaping may affect vascular function as much or more than smoking, MRI study shows

E-cigarettes, or vapes, are largely considered a safer alternative to smoking tobacco cigarettes, but new MRI data suggest they still pose significant risk to users’ health.

Deep learning-based reconstruction nearly halves spinal MRI acquisition times

The accelerated exam does not come at the expense of image quality, according to new work published in Academic Radiology. 

Example of the four types of breast tissue density. The density of fibroglandular tissue inside the breast impacts the ability to easily see cancers. Cancers are very easy to spot in fatty breasts, but are almost impossible to find in extremely dense breasts. These examples show craniocaudal mammogram findings characterized as almost entirely fatty (far left), scattered areas of fibroglandular density (second from left), heterogeneously dense (second from right), and extremely dense (far right).

What breast density status can tell us about cardiovascular risk

Breast density is most often discussed within the context of cancer risk, but new research suggests that it also could be used as a marker of cardiometabolic health.

Positron partners with Upbeat Cardiology Solutions to improve cardiac PET/CT access

Positron, a New York-based nuclear imaging company, will now provide Upbeat Cardiology Solutions with advanced PET/CT systems and services. 

Around the web

CCTA is being utilized more and more for the diagnosis and management of suspected coronary artery disease. An international group of specialists shared their perspective on this ongoing trend.

The new technology shows early potential to make a significant impact on imaging workflows and patient care. 

Richard Heller III, MD, RSNA board member and senior VP of policy at Radiology Partners, offers an overview of policies in Congress that are directly impacting imaging.
