Patients report long-term gadolinium presence in urine
December 12, 2018 -- New data are raising questions about how long it takes gadolinium to exit the body after MRI scans. Using urine samples, researchers from gadolinium patient advocacy group the Lighthouse Project found elevated levels of gadolinium in patients years after their scans -- levels that exceeded the reference levels of some labs.  Discuss
Advanced MRI better option for brain tumor recurrence
December 11, 2018 -- Is PET or MRI better for detecting tumor recurrence in patients with brain metastases who received radiation therapy? While PET and conventional MRI performed about the same, MRI gets the edge if advanced scanning sequences are used, according to a Korean study in the December issue of the American Journal of Roentgenology.  Discuss
NIH wraps up enrollment for adolescent brain study
December 5, 2018 -- The U.S. National Institutes of Health (NIH) has finished enrollment for its Adolescent Brain Cognitive Development study, which will be the largest long-term U.S. study to track brain development in children.  Discuss
Can black bone MRI match CT for pediatric head trauma?
December 3, 2018 -- Black bone MRI may be a viable, radiation-free alternative to CT for the evaluation of children presenting with abusive head trauma -- particularly for detecting skull fractures, according to a Friday presentation at RSNA 2018 in Chicago.  Discuss
DWI-MRI may be best for indeterminate lung nodules
December 3, 2018 -- Diffusion-weighted MRI (DWI-MRI) offers comparable or even superior diagnostic performance to FDG-PET/CT for differentiating malignant and benign pulmonary nodules and masses, according to a meta-analysis published online November 27 in Radiology.  Discuss
A SMART way to reduce pediatric sedation MRI delays
November 30, 2018 -- CHICAGO - Having to wait almost two months for a pediatric MRI scan with sedation is no way to run an imaging facility. It's one of the reasons staff at Montefiore Medical Center in New York City launched the SMART program to better serve this young population, according to a Thursday talk at RSNA 2018.  Discuss
Trust MRgFUS for prostate cancer ablation
November 30, 2018 -- MR-guided focused ultrasound (MRgFUS) is a viable tool for prostate cancer ablation, according to research presented this week at the annual RSNA meeting in Chicago.  Discuss
Gadolinium accumulation might be more widespread than thought
November 29, 2018 -- CHICAGO - Increased signal intensities in different brain regions presumably caused by linear and macrocyclic gadolinium-based contrast agents could be an indication that gadolinium accumulation is more widespread than previously thought, according to a study presented on Wednesday at RSNA 2018.  Discuss
MRI exposes changes to kids' brains from football
November 29, 2018 -- An examination of MRI scans revealed that repeated head collisions incurred while playing football can deform the shape of white-matter tracts -- or bundles of nerve fibers -- in a child's brain, according to a presentation on Thursday at RSNA 2018.  Discuss
fMRI finds brain alterations in gaming addiction
November 28, 2018 -- Functional MRI (fMRI) exams have revealed that internet gaming disorder is associated with gender-specific changes in the brain. Men have alterations in brain regions that affect impulse control, while women do not, according to research presented on Wednesday at the RSNA meeting in Chicago.  Discuss
