DCE-MR imaging of orbital lesions: diagnostic performance of the tumor flow residence time τ calculated by a multi-compartmental pharmacokinetic tumor model based on individual factors

Background Differentiating benign from malignant orbital lesions by imaging and clinical presentation can be challenging. Purpose To differentiate benign from malignant orbital masses using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) based on tumor flow residence time τ calculated with the aid of a pharmacokinetic tumor model. Material and Methods Sixty patients with orbital masses were investigated by 3-T MRI including...
