MRI contrast ferumoxytol causes very few side effects
November 29, 2019 -- Could ferumoxytol replace gadolinium-based contrast agents for some MRI scans? It is a possibility, given that it is well tolerated by patients with chronic kidney disease and caused no serious adverse events, according to a study published in the December issue of Radiology.  Discuss
Add MRI to breast screening for fewer interval cancers
November 27, 2019 -- In a large Dutch study, using supplemental MRI screening in women with extremely dense breast tissue and normal mammograms resulted in significantly fewer interval cancers than using mammography alone.  Discuss
DTI-MRI links obesity to areas of white-matter damage
November 26, 2019 -- Diffusion-tensor MR images (DTI-MRI) have revealed signs of brain damage in the white matter of overweight children, which could be related to several key inflammatory markers, according to a study scheduled for presentation next week at RSNA 2019 in Chicago.  Discuss
Focused ultrasound treatment to brain relieves tremors
November 26, 2019 -- Applying treatments of MR-guided focused ultrasound to the brain can be an effective therapy for people with essential tremor, as well as tremor related to Parkinson's disease, according to a study to be presented at RSNA 2019 in Chicago.  Discuss
fMRI finds opioids may alter brain function in babies
November 26, 2019 -- Functional MRI (fMRI) has shown that prenatal exposure to opioids may alter brain function in babies, according to research scheduled to be presented at the upcoming RSNA 2019 meeting in Chicago.  Discuss
Is this MRI-guided procedure worthy of epilepsy patients?
November 25, 2019 -- An MRI-guided therapy for patients with epilepsy who are resistant to drug treatment has shown that it can extend quality of life. But the technique also comes at a greater cost than surgery, according to a study published online November 20 in PLOS One.  Discuss
MRI scoring system could predict liver transplant need
November 21, 2019 -- European researchers have developed a functional liver imaging score that uses gadoxetic acid-enhanced MRI to help predict which patients with advanced chronic liver disease might need a transplant or are at greater risk of mortality, according to a study published online November 19 in Radiology.  Discuss
fMRI shows how brains rebound from hemispherectomy
November 19, 2019 -- A new study published online November 19 in Cell Reports sheds new light on how some people are able to recover from hemispherectomy -- removal of half their brain -- and still function at a high level. Functional MRI (fMRI) demonstrated how the brain compensates by restoring communication in certain areas to compensate for the loss.  Discuss
Which MRI sequences can best handle metal braces?
November 19, 2019 -- What is the best way to overcome artifacts in patients wearing metallic orthodontic devices? The authors of a new study published November 12 in Radiology recommend slight modifications in functional MRI and diffusion-tensor MR imaging sequences to complete the task.  Discuss
7T MRI finds promising MS biomarker
November 13, 2019 -- Using 7-tesla MRI scans, researchers have identified a potentially valuable biomarker of brain inflammation in patients with multiple sclerosis (MS) that could shed light on how the disease progresses, according to a study published online November 12 in the Multiple Sclerosis Journal.  Discuss
