Conventional clinical breast MRI consists of several separate T₁-weighted scans, including both pre-contrast fat-suppressed and non-fat-suppressed acquisitions as well as the acquisition of dynamic contrast-enhanced phases.

Here, we show how this entire exam can be replaced by a single comprehensive scan, therefore reducing overall scan time and simplifying the clinical workflow. This is achieved by using radial stack-of-stars sampling in combination with a model-based fat/water separation technique, which takes into account the off-resonant blurring of fat and integrates both compressed sensing and parallel imaging. The approach is validated in 24 patients and results were evaluated by two radiologists.
