Diffusion Weighted Imaging (DWI) in combination with simultaneous multislice (SMS) acquisition has the potential to decrease acquisition time and improve image quality in abdominal MRI. In this study, we evaluated the image quality of free-breathing DWI acquired from 25 patients with liver metastases and compared SMS (with/without an advanced processing option) DWI with conventional bipolar echo planar DWI. We found that free-breathing liver DWI based on a SMS-accelerated protocol with advanced processing methods was faster and demonstrated better image quality when compared with a conventional bipolar DWI protocol.
