AHRQ summary offers 3 strategies for CIN prevention
August 24, 2016 -- The U.S. Agency for Healthcare Research and Quality (AHRQ) has released a summary of two major evidence reviews on the risks of contrast-induced nephropathy (CIN), stating there are only three proven strategies for preventing CIN.
Imaging detects telltale signs of Zika infection
August 23, 2016 -- Radiologists reviewing medical imaging scans of babies and fetuses in cases of suspected Zika infection can expect to see a number of telltale brain abnormalities, including loss of gray- and white-matter volume and a "collapsed" appearance of the skull. That's according to a report on the devastating virus published August 23 in Radiology.
MRI shows promise in diagnosing CTE in living patients
August 23, 2016 -- MRI scans four years apart have detected a loss of brain volume in regions associated with chronic traumatic encephalopathy (CTE). The results could be the first time the degenerative neurological condition has been identified in a living person, according to a paper published online August 23 in the American Journal of Geriatric Psychiatry.
Should low-risk women get breast screening every 3 years?
August 23, 2016 -- Some women's health researchers are coming around to the idea of breast screening tailored to a woman's risk of breast cancer. A new study published August 23 in the Annals of Internal Medicine offers support for the idea, but also goes a step further, calling for screening every three years for women at lowest risk of cancer.
Can we talk? Chats with surgeons change treatment plans
August 22, 2016 -- In-person consults between radiologists and acute care surgeons led to changes in medical and/or surgical planning in approximately 40% of cases, according to a study published in the August issue of the Journal of the American College of Radiology.
Lack of reimbursement doesn't slow use of perfusion MRI
August 22, 2016 -- The use of perfusion MRI is growing for neurological applications, even though there is no specific reimbursement for the technique, according to a study published in the August issue of the American Journal of Roentgenology.
Guidelines matter for breast screening referrals
August 19, 2016 -- It seems like almost every medical specialty has its own guidelines for when women should be screened for breast cancer. But are primary care doctors actually paying attention when they refer patients for screening? Yes, according to a study published online August 9 in the American Journal of Roentgenology.
Advanced visualization tool assesses lung disease
August 19, 2016 -- An Australian start-up firm called 4Dx has developed a new technique that combines fluoroscopy and advanced visualization to generate high-resolution images of lung-tissue motion and airflow. The firm hopes the technology will enable researchers to view and measure abnormal function in lung regions at the earliest clinical stages of disease.
How soon will deep learning affect radiology?
August 18, 2016 -- For radiologists concerned about the arrival of deep learning, the future might be here sooner than you think. Deep-learning algorithms could begin producing radiology reports for basic studies like mammography and chest x-rays in as soon as five years, and for most types of imaging studies over the next 20 years.
Is MRI accurate for assessing the age of teen athletes?
August 18, 2016 -- A policy by the Fédération Internationale de Football Association (FIFA) of using MRI to verify the ages of young soccer players perhaps should get the boot, figuratively speaking, based on a number of clinical studies and radiology and orthopedic specialists.
