Implementation and Application of PSF-Based EPI Distortion Correction to High Field Animal Imaging

Figure 5

Example of diffusion weighted image acquisition in a rat. A 4-shot diffusion weighted SE-EPI was used for data acquisition. (a) Original SE-EPI and (b) SE-EPI after DiCo. ADC maps were calculated from original and corrected SE-EPI and are given in (c) and (d). In the SE-EPI (b) and corresponding ADC map (d) a significant improvement in geometric representation can be seen.
