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.

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. 

Incidental interstitial lung abnormalities largely underreported

Less than half of incidental interstitial lung abnormalities on CT exams are reported

This is despite experts cautioning that these findings should be "systematically and fully assessed" due to their progressive nature.

The rapid rise of artificial intelligence (AI) has helped cardiologists, radiologists, nurses and other healthcare providers embrace precision medicine in a way that ensures more heart patients are receiving personalized care.

FDA clears AI screening tool for cardiac amyloidosis

Ultromics designed EchoGo Amyloidosis to evaluate routine echocardiogram results for signs of cardiac amyloidosis. It received the FDA's breakthrough device designation back in 2023.
