Popis: This article discusses the diagnostic benefit of methods for the compensation of motion artefacts in dynamic MRT-Mammography with a contrast agent. Our algorithms for motion compensation perform a locally rigid registration of cubic sub-volumes and a locally affine deformation of tetrahedral sub-volumes from a Delaunay-Triangulation. Within an extensive clinical study, these fast, automatic, and robust algorithms have been applied to 64 MRT-Mammography datasets from the radiological practice of Dr. Friedburg. The comparison of corrected datasets with original data and the statistical evaluation of results show a significantly improved quality of difference images, particularly at the presence of large motion artefacts.
