Quantitative Parameter Mapping in the Abdomen at 7T using Radial QTI Encoding

Quantitative MRI offers diagnostic insights into tissue properties and enables the characterisation of diseases, while reducing variability between operators, sites and vendors. A 2D and a 3D radial sequence using Quantitative Transient State Imaging (QTI) were implemented and optimised to map T1, T2 and Proton Density in the abdomen at 7T. Resulting in-vivo multi-parametric maps were of motivating quality, while validation in the Eurospin TO5 phantom showed good agreement with T1 and T2 Gold standard measurements.
