Effect of using Super-Resolution Technique in Slice Direction on DTI Fiber Tractography

Daniel Gllmar¹, Christian Ros¹, Jrgen R. Reichenbach¹

2-D multislice Diffusion-MRI typically suffers from lower resolution in the slice direction compared to in-plane resolution. Thus, we applied super-resolution technique in slice direction by acquiring overlapping slices (negative slice gap). Based on this dataset we evaluated the effect on DTI fiber tractography. We observe an overall improvement in diffusion property maps (FA, ADC, etc.) as well as in fiber tractography.
