This study evaluated if low field MRI is a practical alternative for Roentgen stereophotogrammetric-analysis (RSA) to measure prosthetic migration. This also included determining the optimal registration method for this purpose. The detection of migration on low field MRI was sufficient for clinical use in two of the translation directions and all three rotational directions. Manual registration proved to be the most accurate method for markerless MRI (MMRI) estimation of the migration.
