Pelvic Doppler ultrasound studies blood flow in the uterus, ovaries, fallopian tubes and surrounding pelvic vessels. By adding colour and waveform analysis to standard ultrasound, it helps doctors understand how well blood is reaching the reproductive organs — information vital in fertility treatment, recurrent miscarriage, and pregnancy complications.
At Unittas Hospital, our fertility team performs more than 4,000 Doppler studies annually using the latest high-resolution machines.
Book Doppler Scan| Clinical Situation | What Doppler Helps Detect |
|---|---|
| Repeated IVF failures | Poor uterine blood flow (high resistance index) |
| Recurrent pregnancy loss (>2 miscarriages) | Uterine artery notching, high PI/RI |
| Thin endometrium despite hormones | Reduced subendometrial blood flow |
| Large fibroids or adenomyosis | Abnormal tumour vascularity, feeding vessels |
| Suspected ovarian torsion | Absent or reversed diastolic flow |
| PCOS with irregular cycles | Increased ovarian stromal blood flow |
| Early pregnancy (11-14 weeks) | Screening for pre-eclampsia & growth restriction |
The machine shows: Red/blue colours for direction of blood flow, waveforms that measure speed and resistance, and numerical values including PI (Pulsatility Index), RI (Resistance Index), and S/D ratio.
| Vessel | Normal PI | Normal RI | Concerning Values |
|---|---|---|---|
| Uterine artery (non-pregnant) | <2.5 | <0.8 | PI >3.0, persistent notching |
| Sub-endometrial spiral arteries | 1.5-2.2 | — | PI >2.5 = poor receptivity |
| Early pregnancy uterine artery | PI <1.6 | No notching | Bilateral notching + PI >2.5 |
High resistance (PI >3.0 or persistent notching) indicates reduced blood flow to the uterus, which can affect implantation. Treatment may include low-dose aspirin, sildenafil, or other interventions to improve blood flow.
Not necessarily for everyone, but it's highly recommended for patients with thin endometrium, previous implantation failures, or recurrent miscarriage. Your fertility specialist will advise based on your history.
Yes, Doppler uses the same sound waves as regular ultrasound. It's completely safe, non-invasive, and uses no radiation. It can be performed multiple times during pregnancy without any risk.
