Ultrasound Pelvic Female (Transabdominal and Transvaginal)
USNo contrastOB-GYN
Indications
- Pelvic pain
- Abnormal uterine bleeding
- Suspected fibroids / adnexal mass
- Postmenopausal bleeding
- Evaluation of IUD position
- Infertility evaluation
- Follow-up of ovarian cyst
Patient prep
- Transabdominal: full bladder (acoustic window)
- Transvaginal: empty bladder; informed consent and chaperone per policy
- Document LMP/menstrual status
Contrast
None / non-contrast
Technique
- Transabdominal: curvilinear 2-5 MHz over full bladder
- Transvaginal: endocavitary 5-9+ MHz with sterile cover/gel
- Sagittal and transverse/coronal planes for uterus and ovaries
- Color Doppler for adnexal/ovarian vascularity as indicated
Series / Sequences
| # | Series / Sequence | Plane | Notes |
|---|---|---|---|
| 1 | Uterus sagittal (long axis) | Sagittal | Measure length and AP; document position/version |
| 2 | Uterus transverse | Transverse | Measure width; myometrial echotexture |
| 3 | Endometrium | Sagittal | Measure thickest portion, echogenic-to-echogenic border, perpendicular to midline; exclude fluid |
| 4 | Cervix | Sagittal | Document |
| 5 | Right ovary | Two planes | Measure in 3 dimensions; volume = L x W x H x 0.52 |
| 6 | Left ovary | Two planes | Measure in 3 dimensions |
| 7 | Adnexa / cul-de-sac | As needed | Free fluid, masses; Doppler of suspicious lesions |
Key points
- Endometrial thickness measured in long axis at thickest point excluding any intracavitary fluid
- Postmenopausal endometrium >4-5 mm with bleeding warrants further evaluation
- TV provides superior resolution for endometrium and ovaries; combine TA + TV when feasible
- Add color/spectral Doppler for suspected torsion or to characterize masses
