This paper is a feasibility study of SWeep Imaging with Fourier Transform (SWIFT) to detect breast pathology. An advantage of SWIFT is that the same scan data can be formatted into hight temporal resolution DCE and high spatial resolution morphological images. Three patients who underwent SWIFT imaging after clinical suspicion of breast pathology, but prior to biopsy, are presented. The following pathology was identified: ductal carcinoma in situ, fibroadenoma, and infiltrating ductal carcinoma. SWIFT MRI shows benign and malignant features similar to clinical DCE MRI and offers numerous advantages. Benefits include faster imaging with excellent spatial and temporal resolution, with reduced T2* effects.
