Dynamic contrast-enhanced breast imaging is typically performed in the prone position, but supine breast MRI is desirable for patient comfort and better correspondence to the surgical position. We have developed a breath-held multiphase supine bilateral DCE breast imaging protocol with Dixon fat-water separation. In this work, we compare the DCE curves to those from the prone diagnostic MRIs in 6 tumors. The shape of the curves is generally preserved, demonstrating that our supine scans are limited primarily by resolution, as opposed to SNR or motion.
