Simultaneous Multi-Slice DWI for Abdomen and Breast Protocols
Diffusion-weighted imaging (DWI) has great potential in body oncology, however, being a single-shot technology, the acquisition is relatively time consuming.
Simultaneous Multi-Slice (SMS)-EPI deploys multiband pulses to excite multiple slices simultaneously. This excitation is combined with a blipped CAIPIRINHA approach during readout to reduce g-factor related SNR loss.
As a result, an additional acquisition time reduction without compromising image quality compared to a standard GRAPPA 2 can be achieved with SMS 2 in combination with GRAPPA 2 in breast and abdominal scans1. Protocols, .exar files and DICOM images for MAGNETOM Aera 1.5T and MAGNETOM Skyra 3T can be downloaded here. Prerequisite: Software version syngo MR E11C and SMS-EPI license.
