摘要
A method of 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 the images, wherein MRI 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; and the T1 and T2 values are extracted for each image pixel or voxel from the corresponding MRI signals.
