This paper presents an investigation of the apparent diffusion coefficient (ADC) for improving the discrimination of benign and malignant lesions in breast magnetic resonance imaging (MRI). In particular a method is presented for automatically selecting hyper intense tumour voxels in dynamic contrast enhanced (DCE) MRI data and evaluating their average ADC in the corresponding diffusion-weighted (DW)...
This paper proffers two non-linear empirical parametric models - linear slope and Ricker - for use in characterising contrast enhancement in dynamic contrast enhanced (DCE) MRI. The advantage of these models over existing empirical parametric and pharmacokinetic models is that they can be fitted using linear least squares (LS). This means that fitting is quick, there is no need to specify initial...
A method that uses microwave pulses to achieve strain imaging of the breast is presented. In the proposed method, the breast is inserted in an enclosure that defines the boundary conditions for the breast deformation under the influence of external pressure. The upper plate of the enclosure, which also includes an antenna array, is attached to a compression tool, whereas the lower and the front plates...
A theoretical model is presented to investigate the possibility of using a hybrid imaging method for early breast cancer detection. It uses the combined microwave and acoustic excitations to exploit contrasts in both the dielectric and elastic properties of malignant and normal breast tissues. The calculated results presented in this paper show that value of the scattering contrast between the malignant...
