Pelvis 3D Ultrasound Scan

What Makes 3D Ultrasound Different from 2D

• 2D ultrasound = flat, single-plane images
• 3D ultrasound = captures hundreds of 2D slices and reconstructs them into a rotatable 3D volume
• Doctors can “fly through” the uterus, ovaries, and surrounding structures, spotting issues that flat images may miss

Key Clinical Benefits of Pelvic 3D Imaging

• Pin-points fibroids, polyps, or cysts within millimetres
• Measures exact volume of ovaries and uterus
• Guides fertility treatments by counting antral follicles
• Detects uterine anomalies causing miscarriages

Definition & Technology

A Pelvis 3D Ultrasound Scan is a non-invasive imaging test that uses high-frequency sound waves and computer software to create three-dimensional pictures of the uterus, ovaries, fallopian tubes, bladder, and pelvic floor.

How 3D Volume Rendering Works

1. Probe emits sound waves
2. Echoes bounce back from tissues
3. Software stacks echoes into a cube of data
4. Physician manipulates the cube to view any angle, slice, or layer

• Uterus: Size, shape, position, endometrial thickness
• Ovaries: Volume, antral follicle count, cysts, tumours
• Fallopian Tubes: Fluid or blockage signs
• Bladder & Pelvic Floor: Wall thickness, residual urine, muscle tone

• Investigating pelvic pain or abnormal bleeding
• Infertility work-up: checks ovulation, uterine lining
• Fibroid & polyp mapping for surgery planning
• Endometriosis assessment—detects deep infiltrating lesions
• Post-surgery follow-up to confirm healing or recurrence

Symptoms Indicating the Scan

• Chronic pelvic pain or pressure
• Irregular, heavy, or painful periods
• Difficulty conceiving for > 12 months
• Suspected fibroids or ovarian cysts
• Post-menopausal bleeding

Age & Gender Guidelines

• Women 18+ with above symptoms
• Transgender men (with uterus/ovaries) on hormone therapy
• Teens only with paediatric gynaecologist referral

Referral Requirements

• GP, obstetrician, or fertility specialist referral
• Walk-ins accepted for routine fertility tracking packages

• Superior anatomical detail down to 0.5 mm
• Non-invasive & radiation-free—safe for repeated scans
• Real-time multiplanar views let doctors rotate images live

• Uterine anomalies (septate, bicornuate uterus)
• Ovarian cysts & tumours (distinguishes simple vs. complex)
• Adenomyosis—thickened junctional zone
• Pelvic Inflammatory Disease (PID)—fluid-filled tubes

• Fasting: Not required for transvaginal scan; fast 4 hours for transabdominal if bladder not sufficiently filled
• Hydration: Drink 1 litre water 1 hour before transabdominal scan; empty bladder before transvaginal scan
• Clothing: Wear loose two-piece outfit; you’ll undress from waist down
• Medications: Continue routine meds; inform sonographer if on blood thinners

• Doctor’s referral on letterhead or digital form
• Previous ultrasound/MRI reports for comparison
• Insurance/TPA pre-authorisation if applicable

• Days 5–10 of menstrual cycle for baseline uterine imaging
• Day 12–14 for follicular tracking
• Avoid menses for transvaginal scans (unless bleeding investigation requested)
• Pregnancy: Anytime after 6 weeks for viability scan

• Minimum age: 18 (unless paediatric referral)
• Contraindications: None; virgin patients can choose transabdominal route

1. Check-in at Cadabams Diagnostics reception
2. Consent form and pregnancy screening questionnaire
3. Positioning—lie on exam couch, knees bent
4. Scanning—10–25 minutes, painless
5. Post-scan care—wipe off gel, receive printed report link within 30 minutes

• Allergy alert: Inform staff if scheduled for contrast-enhanced 3D and have shellfish/iodine allergy
• Pregnancy disclosure: Always required; transvaginal scan safe but optional

Safety Profile

• Zero radiation—safe in pregnancy
• No known side effects
• Probe insertion (transvaginal) may cause mild discomfort but not pain

Diagnostic Limitations

• Cannot visualise bowel loops clearly
• May miss very small (< 3 mm) endometrial lesions
• Obesity can reduce image quality
