A study in the Lancet could lead to a change of paradigm in the early diagnosis of breast cancer. It states that magnetic resonance imaging (MRI) is substantially more accurate than mammography in diagnosing very early stages of breast cancer . Up to now MRI was thought to be hardly suited for the detection of such 'ductal carcinoma in situ (DCIS) .

Concussions are common in young athletes but the underlying changes in brain function that occur have been poorly understood. Now, a University of Pittsburgh School of Medicine study is the first to link changes in brain function directly to the recovery of the athlete.

For women at high risk of breast cancer, use of magnetic resonance imaging (MRI) plus X-ray mammography for screening will detect more breast cancers than mammography alone, a new technology assessment has found. But the number of false positives —indicating a problem where none exists — will rise significantly also.

Ultra-high-field (7T) MRI can detect multiple sclerosis lesions better than MRI which can lead to possible earlier diagnosis and treatment, according to a new study by researchers from Ohio State University in Columbus, and Columbia University in New York.

Abnormalities in the ligaments found on the outside of the knee (lateral collateral ligament complex or LCLC) are commonly seen on MRI in patients with knee osteoarthrosis (OA), according to a study conducted by researchers from Johns Hopkins Hospital in Baltimore, MD and Thomas Jefferson University Hospital in Philadelphia, PA.

Surgery is about to change with the introduction of a new surgical robotic system at the University of Calgary/Calgary Health Region. NeuroArm aims to revolutionize neurosurgery and other branches of operative medicine by liberating them from the constraints of the human hand.
