EMA confirms clampdown on linear gadolinium agents
July 21, 2017 -- It's official: After months of intense lobbying and wrangling, the use of some linear gadolinium contrast agents in MRI will be restricted, and others are to be pulled from the market, following confirmation on Friday that the European Medicines Agency (EMA) has approved recommendations made on 7 July by the Pharmacovigilance Risk Assessment Committee.
Pediatric patient sedation on the rise at one ACO
July 21, 2017 -- A four-year survey of more than 18,000 MRI scans within the Partners for Kids accountable care organization (ACO) showed an increasing need to anesthetize pediatric patients undergoing MRI scans, according to results published in the July issue of the Journal of the American College of Radiology.
fMRI, EEG may detect consciousness in TBI patients
July 20, 2017 -- Researchers from Massachusetts General Hospital are using the novel approach of combining functional MRI (fMRI) and electroencephalography (EEG) to determine the level of consciousness in intensive care unit patients with severe traumatic brain injury (TBI), according to a study published online July 20 in Brain.
Gadolinium found in animal tissue regardless of GBCA type
July 18, 2017 -- Contrary to previous research, a prospective animal study has confirmed the presence of gadolinium deposits in brain tissue after the injection of both linear and macrocyclic gadolinium-based contrast agents (GBCAs), according to results published online in Radiology.
DWI-MRI shows vision changes could predict Parkinson's
July 12, 2017 -- With the help of diffusion-weighted MR imaging (DWI-MRI), researchers in Italy have uncovered changes in the visual systems of patients newly diagnosed with Parkinson's disease, according to a study published online July 11 in Radiology.
Gadolinium retention in brain may be underestimated
June 27, 2017 -- Gadolinium retention in the brain may be more widespread than previous studies have shown, and it may not be limited to patients with brain abnormalities such as a tumor or infection, according to new research published online June 27 in Radiology.
Is ferumoxytol the alternative to gadolinium MRI agents?
June 23, 2017 -- Given the concerns over the discovery of trace amounts of gadolinium in brain tissue long after contrast-enhanced MRI scans, researchers from the University of California, Los Angeles are reporting early success with an iron-based compound, ferumoxytol, to image a wide range of pediatric and adult patients.
MRI + mammography detects recurrent breast cancer
June 22, 2017 -- Adding MRI to mammography improves the detection of recurrent breast cancer in women who have been treated for the disease, according to a study published on June 22 in JAMA Oncology. What's more, MRI appears to be a better option than ultrasound as an adjunct to mammography.
The 'sky is the limit' for 7T MRI research in Boston
June 21, 2017 -- Brigham and Women's Hospital in Boston is making a considerable investment in the future of radiology and patient care with its recent installation of an investigational 7-tesla MRI scanner. While the unit initially will be used for research, the hospital is open to the idea of someday using the scanner clinically.
Breast MR hits benchmarks in community practice
June 15, 2017 -- Breast MRI has been shown to perform well as an adjunct to screening mammography in women at high risk for breast cancer. But its efficacy has mostly been evaluated based on trials at academic centers rather than community practices. So how does the modality perform in the real world?
