Abstract

The invention relates to a method for generating a subject-specific map (20) of a tissue property, in particular the magnetic susceptibility, of a region of interest within a subject, the method comprising the steps of receiving an MR image (2) of the region of interest; feeding the MR image (2) as input into at least one trained neural network (4, 6), wherein the output of the neural network (4, 6) is an output image (8, 10) having improved contrast between bone and air; segmenting (12) the output image (8, 10) into air and at least two types of tissue, namely at least bone and at least one type of soft tissue, to obtain a segmented image; and assigning (14) pre-determined values (16) for the tissue property to each category of tissue and air in the segmented image to obtain the subject-specific map (20) of the tissue property.
