Study: Gadolinium has little impact on accuracy of MRI for pediatric tumors

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.
