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.
