Although useful for the detection of breast cancers, conventional imaging methods, including mammography and ultrasonography, do not provide adequate information regarding response to therapy. Dynamic contrast enhanced MRI (DCE-MRI) has emerged as a promising technique to provide relevant information on tumor status. Consequently, accurate longitudinal registration of breast MR images is critical for the comparison of changes induced by treatment at the voxel level. In this study, a nonrigid…

Registration of DCE MR Images for Computer-Aided Diagnosis of Breast Cancer
TLDR
A registration scheme that employs an elastic model as the deformation model and normalized cross correlation as the similarity term is presented and results indicate that a local similarity metric such as normalizedCross correlation can achieve desirable registration performance.
Nonrigid registration using free-form deformations: application to breast MR images
TLDR
The results clearly indicate that the proposed nonrigid registration algorithm is much better able to recover the motion and deformation of the breast than rigid or affine registration algorithms.
A Nonrigid Registration of MR Breast Images Using Complex-valued Wavelet Transform
TLDR
A fast, slice-by-slice, nonrigid registration algorithm of dynamic magnetic resonance breast images is presented, which allowed a best definition of breast and lesion borders and greater detail detectability and was superior to rigid or affine registration.
The adaptive bases algorithm for intensity-based nonrigid image registration
TLDR
This work proposes a method that permits the spatial adaptation of the transformation's compliance and allows the number of degrees of freedom in the overall transformation to be reduced, thus speeding up the process and improving its convergence properties.
Multimodality image registration by maximization of mutual information
TLDR
The results demonstrate that subvoxel accuracy with respect to the stereotactic reference solution can be achieved completely automatically and without any prior segmentation, feature extraction, or other preprocessing steps which makes this method very well suited for clinical applications.
Evaluation of 3D modality-independent elastography for breast imaging: a simulation study
TLDR
3D MIE was able to successfully reconstruct elasticity images using data obtained from both magnetic resonance and x-ray computed tomography systems, and the lesion was localized correctly in all cases and its relative elasticity found to be reasonably close to the true values.
Dynamic Contrast Enhanced Magnetic Resonance Imaging in Oncology: Theory, Data Acquisition, Analysis, and Examples.
TLDR
This review discusses the basic physics of this methodology, and technical aspects of how DCE-MRI data are acquired and analyzed, and discusses appropriate models of contrast agent kinetics and how these can be used to elucidate tissue characteristics of importance in cancer biology.
Volume-preserving nonrigid registration of MR breast images using free-form deformation with an incompressibility constraint
TLDR
The preliminary results suggest that incorporation of the incompressibility regularization term improves intensity-based free-form nonrigid registration of contrast-enhanced MR breast images by greatly reducing the problem of shrinkage of Contrast-enhancing structures while simultaneously allowing motion artifacts to be substantially reduced.
Modality independent elastography (MIE): potential applications in dermoscopy.
TLDR
A multiresolution extension to a novel elastographic imaging method called Modality Independent Elastography (MIE) is used to characterize the mechanical properties of a skin-like phantom embedded with a mock stiff lesion to demonstrate the potential for characterizing realistic melanoma lesions.
