- CE contrast enhanced
- FoV field of view
- STIR short tau inversion recovery
- VIBE volumetric interpolated breath-hold examination
- EPI echoplanar imaging
- DWI diffusion weighted imaging
- * Dependent on patient height
- ** T1 VIBE of the head was performed pre- and post-contrast. The pre-contrast repetition time was 490 ms
