1. A system for detecting lesions in multi-phase or multi-sequence medical imaging studies of medical images, the system comprising:
at least one memory for storing medical images; and
an electronic processor configured to:
detect native candidate lesions for first phase computer tomography (CT) scans;
detect candidate lesions for second phase CT scans;
project the candidate lesions detected for the first phase CT scans and/or the second phase CT scans on a same common domain;
once the native candidate lesions and the candidate lesions are registered together, perform a matching algorithm for each of the native candidate lesions of the first phase CT scans with the registered candidate lesions from the second phase CT scans to determine presence and contours of valid lesions for the medical images, and to discard the candidate lesions that are not acceptable; and
provide or store the presence and the contours of the valid lesions.
