Estimate of R2* in high-iron patients has many challenges at 3T and above. UTE imaging shows promise as method to perform iron quantitation in heavily iron-loaded tissues. We demonstrate feasibility of using a 3D radial UTE sequence at 3T to estimate R2* relaxation rates in iron-loaded human subjects and fast-decay phantoms.
