The most common MRI sequence for iron overload assessment is Cartesian multiecho gradient-recalled echo (GRE) sequence typically measured in a single breath-hold. However, Breath-holding, is not possible for people who are sedated and is difficult for those who have difficulties with holding their breath for a long period. Ultrashort TE (UTE) imaging is one of the solutions for this challenge. In this method radial data acquisition utilized for free breath scanning. Thus, the main goal of this study is to compare the GRE and UTE sequences on a sample of patients with varying degrees of liver iron overload.
