Across
- 4. Ringing artifact seen at sharp edges in the image.
- 6. Signal loss between adjacent slices.
- 7. Distortion and signal loss at tissue-metal or tissue-air interfaces.
- 9. Blurring or ghosting artifacts from voluntary or involuntary movement.
- 10. Increased signal in tendons positioned at 55° to the magnetic field.
- 11. Ghosting along the phase encoding direction caused by periodic motion.
- 12. Misregistration between fat and water signals causing bright or dark bands at interfaces.
- 13. Loss of spatial resolution when different tissues are averaged within a voxel.
- 14. Line or band of noise across the image.
Down
- 1. Ghosting or signal voids caused by moving blood or CSF.
- 2. Interference pattern of dark and light bands.
- 3. Severe distortion or signal loss near metallic implants.
- 5. Artifact where anatomy outside the field of view wraps into the image.
- 8. Artifact due to under-sampling when using parallel imaging techniques.
