Method for generating 2D or 3D maps of MRI T1 and T2 relaxation times

摘要

A method for generating 2D or 3D maps of MRI T1 and T2 relaxation times by acquiring 2D or 3D MRI gradient-echo images and extracting the T1 and T2 values from said images, whereinMRI images are acquired using a combination of gradient-echo sequences, including:a first MRI image acquired using a SSFP-FID (Steady State Free Precession - Free Induction Decay) acquisition sequence;two further images acquired using a Dual-Echo SSFP acquisition sequence;the T1 and T2 values are extracted for each image pixel or voxel from the corresponding MRI signals.
