Last updated: 12/8/2023
Charge as: Pelvis WWO
Scanner preference: 1.5T
Coil: Torso Coil
- This is the Cervical Cancer protocol, except obliques are relative to the endometrium rather than the endocervical 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 | 5 mm | 1 mm | N | Large FOV to include kidneys. | Top of kidneys → pelvis . Sacrum → anterior abdominal wall. Pelvic pathology is often related to renal pathology. |
SAG | T2 | TSE | 4 mm | 1 mm | N | 200-240 mm. Acetabulum → Acetabulum | If there is a pelvic mass, please scan to include the whole mass. Consider using an anterior Sat band if lots of abdominal wall motion. Matrix 256 x 256 |
SAG | T2 | DWI | 4 mm | 1 mm | SPIR | B50, 500, 1000 | |
AX OBLIQUE | T2 | TSE | 3 mm | 0.5 mm | N | 200-240 mm/ Fit to Patient. Uterus → rectum | Use all planes to obtain true axial of the endometrial canal (see images below). Matrix 512 x 256-512. Freq A-P. |
AX OBLIQUE | T2 | DWI | 4 mm | 1 mm | SPIR | Match AX OBLIQUE | Trigger & track. Free-breathing sequence, so please position slices accordingly. B=50, 500, 1000. |
AX | T1 | TSE | 5 mm | 1 mm | N | 200-240 mm/Fit to Patient. L5 → perineum | If there is a pelvic mass, please scan to include the whole mass. Freq A-P to avoid bowel motion ghosting into uterus and bladder. |
AX | T2 | TSE | 5 mm | 1 mm | N | 200-240 mm/ Fit to Patient. L5 → perineum | Same parameters as AX T1 TSE. Freq A-P to avoid bowel motion ghosting into uterus and bladder. |
SAG | T1 | 3D THRIVE precontrast | -- | -- | Y | Match SAG TSE T2. 240-280 mm | Non-high resolution THRIVEs. |
Hand Inject Contrast | |||||||
SAG | T1 | 3D THRIVE post contrast x3 BH | -- | -- | Y | Match SAG TSE T2. 240-280 mm | NON-high resolution THRIVEs. Perform at 30s, 60s, 90s post contrast. |
AX OBLIQUE | T1 | 3D THRIVE HIGH RESOLUTION postcontrast | -- | -- | Y | Match AX OBLIQUE | HIGH RESOLUTION THRIVEs. |
AX (True Ax) | T1 | 3D THRIVE HIGH RESOLUTION postcontrast | -- | -- | Y | Perineum to renal hila | HIGH RESOLUTION THRIVEs. |
