  3. Towards image registration of dynamic contrast enhanced MRI using deep learning

    Tattersall, AdamThe University of Edinburgh2025

    Dynamic contrast enhanced (DCE)-MRI is a quantitative imaging technique used to monitor microvascular perfusion. It involves rapidly acquiring multiple T1-weighted images over a few minutes whilst injecting a contrast agent, which causes a rapid increase in image intensity. Each type of tissue …
