Normal tissue enhancement on breast MR predicts cancer risk
May 12, 2015 -- Contrast enhancement of normal tissue on breast MRI scans is more effective than tissue density as an imaging biomarker of breast cancer and could make existing risk models more accurate, according to a new study published online May 12 in Radiology.
Mandatory child life counseling calms kids before MRI scans
May 7, 2015 -- A new study from Johns Hopkins Hospital found that requiring pediatric patients to undergo child life consultations prior to an MRI scan significantly reduced the need for anesthesia to keep the children from fidgeting during the exam, according to a study published online April 22 in the Journal of the American College of Radiology.
Knee MRI prices can vary almost 8-fold across the U.S.
May 6, 2015 -- The price of an outpatient noncontrast MRI scan of the knee can vary across the U.S. by almost eightfold, according to a new study in the May issue of the Journal of the American College of Radiology. The finding sheds light on an increasingly consumer-driven healthcare environment, researchers from the Mayo Clinic in Rochester, MN, wrote.
Gadolinium contrast retention raises new safety questions
May 5, 2015 -- A new study by Japanese researchers published on May 5 in Radiology confirms previous findings that traces of gadolinium contrast remain in the brains of people who receive contrast-enhanced MRI scans. The results are raising new questions about the safety of gadolinium-based contrast, such as whether the deposits are harmful.
Safety-net hospital lifts the lid on child abuse
April 29, 2015 -- Fresh data about suspected cases of abuse show that about a quarter of children evaluated at an inner city hospital by means of a skeletal survey with radiography were found to be the victims of abuse. Furthermore, of the abused children, around 39% had skeletal trauma and 61% did not.
fMRI finds women recover more slowly from concussions than men
April 28, 2015 -- A new study published online April 28 in Radiology indicates that women have a more difficult time recovering from concussions than men, based on brain activation patterns seen on functional MRI (fMRI) during working memory tasks. The results hint that more aggressive treatment could be warranted after head injuries in women.
Motion-tracking MRI gives new insight into stroke risk
April 27, 2015 -- Using a novel motion-tracking MRI technique, researchers from Johns Hopkins University have uncovered new evidence that reduced function in the left atrium of the heart may be a sign of increased stroke risk in patients with or without atrial fibrillation.
ARRS: MR tractography touted as 'reliable' imaging biomarker
April 24, 2015 -- Diffusion-tensor MR tractography may be a reliable quantitative imaging biomarker for assessing prostate cancer treatment response to androgen deprivation and radiation therapy, according to a study presented at the American Roentgen Ray Society (ARRS) meeting in Toronto.
NEJM: MRI links brain swelling and cerebral malaria deaths
April 17, 2015 -- After three decades of dedication to the care and treatment of children in Malawi who have cerebral malaria, a group of researchers from around the globe for the first time confirmed that brain swelling is the primary reason why some patients die within days from the condition.
Researchers use MRI to watch finger joints crack
April 15, 2015 -- Joint cracking in the fingers appears to be caused by the rapid formation of a gas-filled cavity in the joints' synovial fluid, rather than the collapse of pre-existing bubbles of air as the joints separate, according to a new study in PLOS One that used static and real-time MRI.
