Promising new MRI technique provides insight into stroke
October 20, 2014 -- Researchers from several institutions have used a 21-tesla preclinical MR spectroscopy scanner to develop a new technique for evaluating patients for stroke and possibly neurodegenerative diseases. They believe the protocol could be migrated to 3- and 7-tesla MRI scanners being used clinically.
MRI shows baseball's wear on teenage shoulders
October 14, 2014 -- It may be America's pastime, but baseball is causing a range of health issues in the young athletes who play it. In a new study published online October 14 in Radiology, MR images revealed abnormal shoulder development and potential long-term issues in male and female teenagers who threw a baseball more than 100 times a week.
ASL-MRI detects early signs of cognitive decline in elderly
October 7, 2014 -- Using arterial spin-labeled (ASL) MRI, Swiss researchers found evidence of cognitive decline in the brains of healthy elderly individuals before symptoms appeared, according to a new study published online October 7 in Radiology.
PET/MRI matches PET/CT with less radiation for children
October 6, 2014 -- German researchers have found promising evidence that PET/MRI is equivalent to PET/CT for lesion detection in pediatric cancer patients, while at the same time delivering just one-quarter of the radiation dose, according to a study published in the October issue of Radiology.
MRI aids differentiation of traumatic cerebral fat embolism
September 18, 2014 -- An Egyptian-led team of MRI researchers reported at last week's International Congress of Radiology that cerebral fat embolism (CFE) can be differentiated from diffuse axonal injury because CFE has a higher incidence of increased T2-FLAIR and diffusion-weighted imaging lesions.
ECRI details need-to-know information for buying an MRI scanner
September 12, 2014 -- What key issues should you keep in mind when buying an MRI scanner? Nonprofit research organization ECRI Institute hopes to help with a new report on performance and other measures that radiology departments and imaging centers should consider when purchasing a new system.
Clinical audit sheds light on breast MRI performance
September 11, 2014 -- You can't manage what you can't measure. This maxim by quality expert W. Edwards Deming can easily be applied to breast MRI: Despite its growing use, the exam still lacks adequate benchmarks for assessing quality, according to a study published in the September Journal of the American College of Radiology.
MRI protocol links gray-matter changes to MS severity
September 10, 2014 -- Using a homegrown MRI protocol, researchers found that a loss of myelin in the gray matter of multiple sclerosis (MS) patients' brains was a strong indicator of disease severity, according to a study published online September 10 in Radiology.
Start-up advances MR-guided procedures with software platform
September 4, 2014 -- Wisconsin researchers are developing a new software platform that would allow surgeons to observe the brain in real-time on MRI during surgical and therapeutic drug interventions. The goal of their company, called InseRT MRI, is to develop customized MRI-guided minimally invasive procedures.
DTI-MRI shows how Wii can improve balance in MS patients
August 27, 2014 -- Using diffusion-tensor MRI (DTI-MRI), Italian researchers detected brain changes related to improved balance and movement in multiple sclerosis (MS) patients who regularly trained on a Nintendo Wii balance board for 12 weeks. Results were published online in Radiology.
