Scan notes:
- This is the Cervical Cancer protocol, except obliques are relative to the endocervical canal rather than the endometrial canal.
- Send ADC maps and subtractions
- FOV: do not include patient’s arms

| Plane | Weighting | Mode | Slice | Gap | FAT SAT | FOV | Notes |
|---|---|---|---|---|---|---|---|
| Cor | T2 | SSTSE BH | 5mm | 1mm | N | Top of kidneys to pelvis. | Scan sacrum to anterior abdominal wall. CONFIRM GOOD COIL PLACEMENT. Large FOV to include kidneys. Pelvic pathology is often related to renal pathology. |
| Axial | T1 | TSE | 5mm | 1mm | N | 20-24mm. Fit to patient. | Scan iliac crest to perineum. Freq A-P to avoid bowel motion ghosting into uterus and bladder. If there is a pelvic mass, please scan to include the whole mass. |
| Axial | T2 | TSE | 5mm | 1mm | N | 20-24mm. Fit to patient. | Scan iliac crest to perinum. Same parameters as AX T1 TSE. Freq A-P to avoid bowel motion ghosting into uterus and bladder. |
| COR | T2 | TSE FS | 4mm | 0.5mm | N | 20-24mm. Fit to patient. | Scan sacrum to anterior to abdominal wall. Freq A-P. |
| Sag Oblique | T2 | TSE | 4mm | 0.5mm | N | 24mm. Fit to patient. | Scan mid-femoral head to mid-femoral head. Freq A-P.Consider using an anterior Sat band if lots of abdominal wall motion. Slices relative to the uterus! Matrix 512 x 256-512. |
| AX Oblique | T2 | TSE | 3mm | 0.5mm | N | 20-24mm. Fit to patient. | Scan Uterus to rectum. CALL Rad FOR PLANNING! PERPENDICULAR to the endocervical canal! Use all planes to obtain true axial of the endocervical canal (see images below). Resulting image should be a true "donut." Matrix 512 x 256-512. Freq A-P. |
| AX Oblique | T1 | 3D THRIVE HIGH RESOLUTION pre | Y | Match AX Oblique | HIGH RESOLUTION THRIVEs. | ||
| SAG Oblique | T1 | 3D THRIVE pre-contrast | Y | Fit to patient | Match SAG Oblique TSE T2. NON-high resolution THRIVEs. |

| Plane | Weighting | Mode | Slice | Gap | FAT SAT | FOV | Notes |
|---|---|---|---|---|---|---|---|
| SAG Oblique | T1 | 3D THRIVE post-contrast x3 BH | Y | Fit to patient. | Match SAG Oblique TSE T2. NON-high resolution THRIVEs. Preform at 30's, 60's, 90's post contrast. | ||
| AX Oblique | T1 | 3D THRIVE HIGH RESOLUTION post-contrast BH | Y | Match AX Oblique | HIGH RESOLUTION THRIVEs. | ||
| AX Oblique | T2 | DWI | 5mm | 1mm | SPIR | Match AX Oblique | Trigger & track.Free-breathing sequence, so please position slices accordingly.B=0, 500, 1000. |
| AX Oblique | T2 | IVIM | 4mm | 1mm | SPIR | Match AX Oblique | B=0, 10, 20, 30, 40, 50, 75, 100, 200, 400, 800. ONLY IF SCANNED on MRI4!!! |
