Sacrum to anterior abdominal wall
Contrast Injection
AXIAL T1 TSE MV MS 3.5mm 1mm SPIR Fit to Patient Iliac crests through pubic symphysis. Same parameters exactly as in pre-contrast AXIAL T1 THRIVE sequence—to detect hemorrhage in cyst or endometrioma and to confirm fat in dermoids. Please also send subtraction images to PACS (subtraction = post-contrast ax T1 THRIVE – pre-contrast ax T1 THRIVE)
COR T1 TSE MV MS 3.5mm 1mm SPIR Fit to Patient Parallel to long axis of uterus.
Pelvic sidewall to pelvic sidewall
SAG T1 TSE MV MS 3.5mm 1mm SPIR Fit to Patient Skin to skin
Notes: For larger patients, slice thickness may be increased up to 5mm.
Breathhold for THRIVE sequences if patient is able.
Images must be checked by radiologist or radiology resident before patient leaves.
