Readout-Segmented Diffusion Tensor Imaging (RS-DTI) Acceleration Using Simultaneously Acquired Slices

The advent of slice accelerated imaging has allowed the significant speedup of diffusion tensor imaging. Slice accelerated imaging excels at accelerating imaging which has a relatively long repetition time, such as readout segmented imaging, which is inherently a dual-echo imaging technique and typically has a repetition time of over 100ms. This work demonstrates that the image quality of diffusion tensor readout segmented imaging is comparable to non-slice accelerated imaging, despite the acquisition being at least 2 times faster.

After one year, current ISMRM & ISMRT members get free access to both the abstracts and videos. Non-members and non-registrants must purchase access via the ISMRM E-Library.

After two years, the meeting proceedings (abstracts) are opened to the public and require no login information. Videos remain behind password for access by members, registrants and E-Library customers.
