Table 1. Comparison of SE-DWI and Segmented-EPI DWI.
SE-DWI | Segmented-EPI DWI |
---|---|
Reduced sensitivity to magnetic susceptibility and geometric distortion artefacts | Prone to distortion artefacts and increased demands on the gradient set |
Long acquisition time | Shorter acquisition time allows acquisition of more diffusion-encoding directions or more averaging |
Relatively low SNR in diffusion weighted images within a limited experiment time | Suitable image quality to study anatomical structures. Allows thinner slices with more averaging to reduce partial volume effects |
Unacceptable experiment due to long experiment times and high SAR at short TR values | Provides reproducible results in a tolerable experiment time |
