fMRI shows age influences recovery time from TBI
October 6, 2015 -- Many older patients recover more slowly from concussions than younger individuals, based on different brain activation patterns seen on functional MRI (fMRI) scans. The study results, published online October 6 in Radiology, suggest that mild traumatic brain injury (TBI) may have a more profound and lasting effect among older people.
Novel breast MRI technique could reduce biopsy rate
September 30, 2015 -- A shorter noncontrast-enhanced breast MRI protocol might help reduce the number of unnecessary biopsies by gathering additional information about suspicious lesions found on screening mammography while cutting scanning times, according to a new study published online September 29 in Radiology.
3D models put pediatric hearts in surgeons' hands
September 28, 2015 -- Researchers from the Massachusetts Institute of Technology and Boston Children's Hospital have developed an automated software method for converting 3D MRI scans of a pediatric patient's heart into a tangible model that surgeons can use to plan operations.
ASCO BCS: Breast MRI useful for average-risk women, too
September 25, 2015 -- SAN FRANCISCO - Breast MRI is used as an adjunct to mammography for screening women at high risk of breast cancer, but could it be used in average-risk women as well to find cancer earlier? The answer is a resounding yes, according to research presented at the American Society of Clinical Oncology's annual Breast Cancer Symposium (ASCO BCS).
Does preoperative breast MRI really benefit patients?
September 24, 2015 -- Breast MRI is a sensitive modality that finds cancers mammography or ultrasound can miss. But when it's used preoperatively in women who have already been diagnosed, it may cause more trouble than it's worth -- such as longer wait times for surgery and unnecessary mastectomies, according to a new study published in JAMA Oncology.
DTI-MRI links hypertension to brain damage, cognitive deficits
September 17, 2015 -- Researchers using diffusion-tensor MRI (DTI-MRI) have found that high blood pressure can damage nerve tracts that connect different parts of the brain, according to a study presented this week at the American Heart Association's 2015 Hypertension Scientific Sessions in Washington, DC.
Timely MRI finds more brain bleeds in military TBI patients
September 15, 2015 -- The sooner a person with a traumatic brain injury (TBI) undergoes an MRI scan, the better the chances of finding microbleeds in the brain, according to a study of military personnel published online September 15 in Radiology.
Structured reporting improves quality of MRI reports
September 10, 2015 -- While some traditions should be valued and retained, the old standard free-text radiology report might not be one of them. At Brigham and Women's Hospital, a structured reporting template yielded a significant improvement in the quality of MRI reports for the crucial task of staging rectal cancer.
PET/MRI can be a boon for pediatric cancer patients
September 9, 2015 -- Young pediatric patients may benefit from FDG-PET/MRI for staging and clinically evaluating oncologic disorders, given the hybrid modality's superior soft-tissue contrast and significantly lower radiation dose, according to a study published online August 24 in Investigative Radiology.
Gadobenate dimeglumine OK for renal-deficient patients
September 2, 2015 -- Researchers from Emory University found no incidence of nephrogenic systemic fibrosis (NSF) using gadobenate dimeglumine MR contrast media in renal-failure patients after more than two years of follow-up, according to a study published in the September issue of Radiology.
