Abstract (EN): The pelvic floor dysfunction includes common conditions like urinary incontinence and pelvic organ prolapse. The pelvic floor has a relevant role on organ support and, therefore, pelvic floor biomechanical models play an important role on the clinical and research settings. Magnetic Resonance images and the Finite Element Method are often used in the modeling process. In this work, the direction of the fibers of the pubovisceral muscle were compared by using Magnetic Resonance Imaging-based tractography and the Maximum Principal Stress Lines obtained by numerical simulation. Mean absolute and mean percentage of relative error were assessed. There were discrepancies on the muscle fiber direction obtained from both methodologies. The insertion areas of the muscle presented increased error when compared to the central area, where the pubovisceral muscle surrounds the rectum. The methodologies for numerical simulation may gain from information provided by the tractography. © 2014 Taylor & Francis Group, London.
