titleOfInvention | Mri method for determining signature indices of an observed tissue from signal patterns obtained by motion-probing pulsed gradient mri |
abstract | A method for determining a signature index of an observed tissue comprises the step of providing (12) a generic attenuation model of a motion-probing gradient pulse MRI attenuated signal S(b), and providing (14) a reference model parameter vector (p R (i)) corresponding to a reference state of the tissue. On the basis of the evolution of the determined (16) partial differential sensitivities dS i (b) of the model attenuated signal S(b) to each model parameter p(i) at the neutral state attenuated signal S N (b) versus b values, a discrete and narrow size set of key b is built (18) and a series of MRI images of the observed tissue are acquired (20) by using the key b values. Then, for each voxel a signature index (sADC(V), Sdist(V), SCdist(V), Snl(V), SI(V)) of the voxel V is determined (22) as a scalar function depending on a distance between the voxel signal pattern acquired at the key b values and the signal pattern of the reference state of the tissue at the same key b values. An apparatus is configured for implementing such a method. |
