Guideline to a sequence of scanning (for both transvesical and transvaginal exams)
- Sag midline uterus. Measure length and AP dimension. Measure endometrial stripe
- Trans uterus (largest view). Measure width.
- Sag uterus, right
- Sag RT ovary, with and without measurement – length and AP dimension
- Color image and pulse doppler of artery and pulse doppler of vein
- Trans RT ovary, with and without measurement – width dimension
- Sag uterus, left
- Sag LT ovary, with and without measurement – length and AP dimension
- Trans LT ovary, with and without measurement – width dimension
- Color image and pulse doppler of artery and pulse doppler of vein
- Trans vagina
- Trans cervix
- Trans body
- Trans fundus
- Trans superior to uterus
Both transabdominal and transvaginal exams should be performed unless there is a clinical reason not to perform the transvaginal exam
For endovaginal only exams- Follow the same Guideline for sequence of scanning as below
Uterus:
Sagittal views (right, left, and midline including cervix). Measure length and AP of uterus. Measure endometrial stripe
Transverse views (above uterus, fundus, body, cervix). Measure width.
Ovaries:
Sagittal and transverse views of both ovaries. Measure ovaries in three dimensions. (length and AP on sagittal view, width on transverse view)Notes:
- measure endometrial stripe in sagittal view, not transverse view. In postmenopausal women, hormonal history important. In premenopausal women, LMP history important
- show abnormalities in sagittal and transverse views, measure in three dimensions (length and AP on sagittal view and width on transverse view
Follicular study (infertility/in vitro)
Follicular measurement. Measurement of follicles greater than 5mm (three dimensions).Although ovarian torsion is partially a clinical diagnosis, ultrasound findings that can be helpful in the diagnosis include:
