We show initial results from efforts to develop and optimize a breast imaging protocol with SWeep Imaging with Fourier Transformation (SWIFT). An advantage of SWIFT, due to 3d radial k-space sampling, is that the same MRI data can be reformatted into high temporal resolution DCE images at lower spatial resolution or high spatial low temporal resolution morphological images. In addition the short dead time makes SWIFT immune to high field R2* effects which can confound T1 based quantitative DCE MRI analysis. At this early stage of development, the quality of SWIFT images in terms of depicting breast morphology is already comparable to that as 3d gradient echo images
