Minimizing in vivo off-resonance distortions in 3D SoS EPI with multishot acquisitions. Due to its relatively low pixel bandwidth in the EPI phase-encode dimension (31.9 Hz), single-shot EPI suffers from signal dropouts in regions with large off-resonance, such as near the sinuses (white arrows). This is mitigated when the 3D SoS EPI readout is divided into multiple shorter shots. There are no visible distortions at any multishot factor in the region targeted for thalamotomy (red arrow).
