MR Female Pelvis for Uterine Cancer Staging WWO BODY Protocol

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
RadioGraphics 2014; 34:1082–1098 Figure 2. Obliques. Illustration shows a uterus that is ante¬riorly rotated in the sagittal plane (anteverted) and laterally tilted to the left in the coronal plane. The double oblique sequence is performed by an¬gling images anteriorly in the sagittal plane (green line) and laterally in the coronal plane (blue line), which creates true oblique images along the true axis of the uterus (orange line). A = anterior, P = posterior.

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.
