Abstract
Dynamic magnetic resonance imaging MRI acquisitions are used in the clinical assessment of the pelvic organs behaviour during an abdominal strain. The main organs (bladder, uterus-vagina, rectum) undergo deformations and intrinsic movements along a sequence. Anatomical references and measurements are generally used by clinicians to evaluate pathology grades. In this context, we have established quantitative elements, which consist of deformation and movement features, for the pelvic dynamic characterization, by using shape descriptors computed from organ contours. Moreover, the deformation and movement features relevance has been assessed towards an efficient sequence discrimination and pathology detection.
