Gadolinium chelate administration is largely unnecessary for imaging pediatric tumors when performing MRI or combined PET/MR scans, according to a recent study published by the Journal of Nuclear Medicine.
Heike E. Daldrup-Link, MD, PhD, Stanford School of Medicine, and colleagues compared the accuracy of gadolinium chelate-enhanced and unenhanced MR images of 119 pediatric patients. They also compared the accuracy of gadolinium chelate-enhanced and unenhanced 18F-FDG PET/MR images for 36 pediatric patients.
Overall, the researchers found that gadolinium chelate administration made no significant difference in the diagnostic accuracy of MR or 18F-FDG PET/MR images of pediatric tumors. Read more.
