No gadolinium, no problem: Specialists can monitor MS patients with unenhanced MRI

Gadolinium-based contrast agents (GBCAs) are typically administered during follow-up imaging of multiple sclerosis (MS) patients. According to new research published in Radiology, however, unenhanced MRI scans are sufficient.

Abdominal MRI patients move less when holding breath at end of exhale

To cut respiratory motion artifacts on liver MRI, have patients hold their breath at the end of an exhale rather at the end of an inhale. That’s the recommendation of Stanford researchers after testing and comparing the two techniques, and it holds for unenhanced and contrast-enhanced scans.

Should pediatric patients be excluded from MRI research due to stress, anxiety? 

Children and teenagers undergoing brain MRI scans experience little to no more claustrophobia or other form of anxiety than adults, so there’s no reason to exclude pediatric patients from MRI research on the basis of concern over stress.
