Direct Quantification of Gadolinium Retention in Young Patients by ICP-MS Analysis of Extracted Teeth

In this 10-patient prospective pilot study, we show feasibility of pragmatic, direct ex vivo measurement of gadolinium retention from group II gadolinium-based contrast agents (GBCAs) in young patients following routine tooth extraction. This noninvasive method may support future research attempting to understand the link between GBCA exposure and clinical outcomes.
