DTI-MRI algorithm helps evaluate mild TBI, migraines
February 2, 2016 -- An easy-to-use, automated computer algorithm based on diffusion-tensor MRI (DTI-MRI) scanning is helping to evaluate people with mild traumatic brain injury (TBI). Researchers hope the algorithm will spur more widespread adoption of DTI-MRI in the clinical setting, according to a study published February 1 in Radiology.
Smart Choice MRI promotes low-cost MRI scans
February 1, 2016 -- With insurance premiums and out-of-pocket expenses continuing to escalate for most healthcare consumers, one company is trying to make MRI scans more accessible and considerably more affordable -- at $600 or less per scan.
Fatty liver linked to heart failure in obese patients
January 27, 2016 -- Fatty liver is an independent risk factor for heart failure in obese patients -- that is, those with a body mass index of 30 or higher, according to a new study published online January 26 in Radiology. The finding suggests that concrete interventions to stave off nonalcoholic fatty liver disease, also called hepatic steatosis, could help these patients stay healthy.
MRI use causes gadolinium levels to rise in SF Bay
January 26, 2016 -- A new study has found that levels of gadolinium have been rising steadily in the waters of San Francisco Bay over the past two decades. The study attributes the rising levels to growing use of gadolinium for scientific and medical applications, in particular as a contrast agent for MRI scanning.
Cardiac perfusion PET/MRI may be more accurate than SPECT
January 25, 2016 -- Perfusion imaging with PET/MRI could offer a "comprehensive myocardial ischemic evaluation" with shorter scan times than SPECT and a lower radiation dose for patients, according to a pilot study from Washington University and Barnes-Jewish Hospital in St. Louis.
MRI waiting room amenities improve patient satisfaction
January 20, 2016 -- MRI centers that provide a comfortable waiting environment with a variety of conveniences may see happier patients -- who may even believe they're spending less time waiting, according to a study published online January 4 in the Journal of the American College of Radiology.
Gadolinium MRI contrast not needed to evaluate pediatric tumors
January 13, 2016 -- There is no need to use gadolinium-based contrast agents with MRI scans to evaluate tumors in pediatric patients, since image quality is essentially the same with no contrast enhancement at all, according to a study published in the January issue of the Journal of Nuclear Medicine.
3T MRI could become routine for fetal anomalies
January 12, 2016 -- Advances in technology and software have made 3-tesla MRI a better option for examining fetal abnormalities, with no adverse effects on the fetus, according to a study published in the January issue of the American Journal of Roentgenology.
CT shows merit in shoulder as metal implants confound MRI
January 7, 2016 -- The increased use of metallic screws and other fixation devices to repair shoulder injuries is making CT a more effective imaging option than MRI for evaluating postoperative results.
Are radiologists vexed by some BI-RADS breast MRI categories?
January 6, 2016 -- Radiologists tend to agree with established BI-RADS categories when it comes to deciding how to manage patients based on breast MRI exams. But they have room for improvement in some areas, according to a new study published in the American Journal of Roentgenology.
