| Special Instructions: |
| Adust FOV to affected area |
| Mark site of symptoms |
| "Axial" in the foot is parallel to long axis of the metatarsals. "Coronal" is perpendicular to the long axis of the metatarsals. |
| Cover from midfoot through toes; all of foot dorsal to plantar; all of foot medial to lateral. |
|
|
| * Perform sagittal T1 and post-Gad sagittal T1 FS if there is dorsal or plantar ulcer, sinus tract, swelling, etc. Perform axial T1 and post-Gad axial T1 FS if there is medial or lateral ulcer, sinus tract, swelling, etc. |
| ** Scan in plane orthogonal to series 2, 4, and 7. Uses low matrix/large voxel. Should be approx. 1-2 min. long |
| Indications: abscess in the foot , infection in the foot , inflammation , osteomyelitis in the foot |

If metal is in the area of interest or near enough for artifact to effect it:
- if option is available, use WARP option with VAT @ at least 50% (can go higher for larger implants)
- Use a high receiver bandwidth (approx. 500 Hz/pixel)
- for T1 or PD-weighted fat-saturated sequences, turn off all fat-saturation
- for T2-weighted fat-saturated sequences, substitute in STIR sequences with the same geometric parameters; STIR sequences must be performed pre-contrast due to the possibility of contrast-enhancing areas being nulled due to the short inversion time
