METODO PER LA GENERAZIONE DI MAPPE DEI TEMPI DI RILASSAMENTO T1 E T2 IN MRI

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, 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;
the T1 and T2 values are extracted for each image pixel or voxel from the corresponding MRI signals.
