High spatiotemporal resolution (STR) breast MRI offers the potential to improve diagnostic accuracy and characterization of cancer. We utilized a novel approach to sampling k-space and reconstructing images with view-sharing to provide high STR MRI with a temporal resolution of 27 seconds, six-times faster than the clinical standard-of-care, while maintaining high spatial resolution. We performed an intra-patient study to compare image quality between exams. Image quality of the high STR MRI was affected by the higher parallel imaging factor; however, differences were small and diagnostic image quality was maintained. This technique is promising for allowing advanced analysis of perfusion.
