Deep Resolve Swift Brain utilizes a multi-shot echo planar imaging (EPI) approach that enables faster acquisition. In a very SWIFT acquisition, all typical contrasts for routine brain imaging are generated. T2 and T2* are measured simultaneously, which can save additional time. A static field correction is applied to reduce distortions.

Within this multi-shot EPI approach, T2 and T2* are acquired simultaneously by a Siemens Healthineers exclusive EPI-implementation, further accelerating this protocol. Reduced geometric distortions with multi-shot EPI Multi-shot EPI-based T2 dark-fluid reduces imaging times substantially compared to standard TSE imaging and offers true FLAIR contrast due to magnetization transfer preparation. The combination of multi-shot EPI imaging and Deep Learning Reconstruction enables net scan times of less than two minutes. 5 Effective Date: 05 May 2022 | HOOD05162003273224 Unrestricted © Siemens Healthineers, 2022 Deep Resolve Swift Brain with multi-shot EPI – SIEMENS Healthineers General Overview Routine Resolution • Multi-shot EPI is available for Spin Echo Contrast Geometry System Physio Inline Sequence Part 1 Part 2 Special Assistant (ep2d_se_ms) and Gradient Echo (ep2d_fid_ms) Sequence Name epse Bandwidth 752 4 Hz/Px Echo Spacing 1,42 ms EPI Excitation Standard Optimization None RF Pulse Type Normal • It supports latest features, such as SMS, Gradient Mode Fast Segments 2 6 SliceAdjust, Fast GRE Ref Scan, Deep Learning EPI Factor 32 Recon.
