Abstract

A computer-implemented method is proposed for quantifying one or more regions of interest (ROIs) of an organ or tumour. The method comprises: acquiring a first MRI sequence of a first sequence type, referred to a source sequence, and one or more second MRI sequences of at least a second sequence type, referred to as target sequences, the source and target sequences representing the ROIs of the organ or tumour of a patient under examination; segmenting the source sequence by using a trained AI model to obtain a labelled source sequence including a set of labels; transferring the labels from the source sequence to the target sequence(s) to obtain one or more labelled target sequences enabling identification of the ROIs in the labelled target sequence(s); and calculating ROI parametric information from voxel values identified by a respective label of the labelled target sequence(s) as processed or unprocessed to obtain region-specific information about the ROls.
