A deep-learning algorithm beat thoracic radiologists at classifying fibrotic lung disease, according to research published Sept. 15 in The Lancet Respiratory Medicine.

An artificial intelligence (AI) algorithm created by NYU School of Medicine researchers distinguished between two forms of lung cancer with 97 percent accuracy, according to a study published in Nature Medicine.

Brain MRI scans of concussed university hockey players showed the protective tissue insulating brain cell fibers became jarred loose two weeks after injury—despite being cleared to return, research published in the Frontiers in Neurology revealed.

Quantifying liver surface nodularity (LSN) from CT scans can accurately and quickly identify clinically significant portal hypertension in cirrhosis patients, according to a Radiology study.

The ability to walk upright on two feet required millions of years of evolution, and even today humans are not perfectly adapted to bipedalism, argued authors in a recent Academic Radiology perspective.

Functional MRI (fMRI) may be the key to identifying specific neurons in the brain that are central to distinguishing bipolar disorder from depression, reported researchers in a recent Biological Psychiatry: Cognitive Neuroscience and Neuroimaging study.

Researchers at Purdue University in West Lafayette, Indiana, are creating a photoacoustic tomography probe that combines optical and ultrasound techniques to improve diagnosis of common and costly diseases.

Medical imaging has experienced rapid growth in the U.S., with an estimated 80 million CT exams alone performed annually. Authors of a recent Journal of the American College of Radiology study asked: How does abdominal imaging impact the environment?

MRI measurement of small bowel motility was found to be as effective as invasive techniques in measuring Crohn's disease activity, authors of a recent Radiology study reported. The method may reduce the need for endoscopy.

German and Russian researchers have developed a new injection diagnosis system based on magnetoferritin that may improve MRI accuracy, cancer diagnosis and treatment options.
