Partially absorbable surgical mesh implants can be used to treat Pelvic organ prolapse, which is a common disease in elderly women. When it comes to post-operative complications, MRI could be used to qualify movement or deformation of the implant, but current available mesh implants are not visible in MR images. In this work MR measurements are presented to develop and optimize an MR-visible mesh-implant made of threads with magnetic particles. Particle concentrations were determined based on relaxometric evaluation, and thread material was tested for its MR visibility.
