Most countries have not introduced nationwide prostate-cancer screening, as current methods result in overdiagnoses and excessive and unnecessary biopsies. A new study by researchers at Karolinska Institutet in Sweden, which is published in the New England Journal of Medicine, indicates that screening by magnetic resonance imaging (MRI) and targeted biopsies could potentially cut overdiagnoses by

Collaborative research between the University of Kentucky (UK) and University of Southern California (USC) suggests that a noninvasive neuroimaging technique may index early-stage blood-brain barrier (BBB) dysfunction associated with small vessel disease (SVD). Cerebral SVD is the most common cause of vascular cognitive impairment, with a significant proportion of cases going on to develop dementia.

According to an open-access article in ARRS’ American Journal of Roentgenology (AJR), in lumbar spine MRI, presumptive pain generators diagnosed using symptom information from brief electronic questionnaires showed almost perfect agreement with pain generators diagnosed using symptom information from direct patient interviews. “Using patient-reported symptom information from a questionnaire, radiologists interpreting lumbar spine MRI converged

A new study from University of Alberta cardiac researchers casts doubt on the standard practice of using magnetic resonance imaging (MRI) to help diagnose the causes of heart failure not related to a heart attack. In a study published in the journal Circulation, 500 patients with heart failure from Canada and Finland were randomly selected

When it comes to medical imaging, pediatric radiologist and biomedical engineer Shreyas Vasanawala knows that kids aren’t the same as adults. Vasanawala, MD, Ph.D., professor of radiology at the School of Medicine, has spent the last 10 years studying how to improve magnetic resonance imaging scans for his smallest, wiggliest patients. Now, he’s putting his

Our ability to remember past events develops rapidly in the first couple of years of life, but it’s not clear exactly how this happens. Researchers at the Center for Mind and Brain at the University of California, Davis have now been able to carry out functional MRI brain scans of sleeping toddlers, and show for
