DOI: 10.1007/s11548-018-1710-1
Abstract: PurposeAnnotation of meaningful landmark ground truth on DCE-MRI is difficult and laborious. Motion correction methods applied to DCE-MRI of the liver are thus mostly evaluated using qualitative or indirect measures. We propose a novel landmark… read more here.
