The effect of elastic and affine motion correction in dynamic contrast enhanced MRI ofthe temporomandibular joints in children is investigated. Imaging in children is particularly difficultdue to motion. This hampers DCE-MRI and pharmacokinetic estimations for their potentialdiagnostic value in these children with Juvenile Idiopathic Arthritis with possible TMJ involvement.The relative enhancement curves obtained with different motion correction approaches arecompared with the curves calculated with the Gamma Capillary Transit Time model. It is found thatwhen image registration is applied, a greater number of participants can be analysed. The elasticmotion correction approach outperforms the affine approach.
