Deep learning model aids differentiation of colon cancer, acute diverticulitis

A three-dimensional (3-D) convolutional neural network (CNN) can be used as an artificial intelligence (AI) support system for differentiating colon carcinoma (CC) and acute diverticulitis (AD) on computed tomography (CT) ...

Could that breast pain be cancer? When to get a mammogram

If you've ever felt pain, tenderness and tightness—maybe even a sharp, stabbing sensation—in your breasts, it's hard not to jump to conclusions. Could it be the "C" word?

New 3D ultrasound may improve accuracy of liver cancer treatment

A simulated study by researchers at Western University and Lawson Health Research Institute has found a new system that uses ultrasound to construct 3D-images could make treatment of liver cancer, using thermal ablation, ...

Neuroscience

Cerebellum better visualized with the help of new technology

The cerebellum, or our little brain, is mainly responsible for our motor skills. Furthermore, the structure is important for behavior and cognition. The cerebellum is a part of your brain located at the back of your head, ...

Diagnostic tests 'just to be on the safe side' not recommended

Paradoxical maybe, but it's what often happens in the health services: When you ask for an MRI to be on the safe side, your uncertainty increases, says Bjørn Hoffman, a professor at the Department of Health Sciences at the ...

Variety in enamel composition may predict later tooth health

Tooth decay has forced unpleasant dental visits on most of the U.S. population. In fact, over 90% of adults have had at least one cavity. Furthermore, longer lifespans and egregious dental health disparities are contributing ...

New X-ray technology can improve COVID-19 diagnosis

A research team at the Technical University of Munich (TUM) has, for the first time, produced dark-field X-ray images of patients infected with COVID-19. In contrast to conventional X-ray images, dark-field images visualize ...

Could synthetic X-rays solve a gap in medical imaging data?

Medical doctors who specialize in rare disease get only so many opportunities to learn as they go. The lack of diverse health care data to train students is a key challenge in these fields. "When you are working in a setting ...
