Transvaginal Dating Ultrasound Scan (TVS)

• Quick Definition: A ULTRASOUND SHORT SCAN is a focused, low-duration ultrasound that captures only the most critical images.

• Difference: Unlike a complete ultrasound study that evaluates multiple organs and structures, the short scan zeros in on 2–4 specific parameters.

What is ULTRASOUND SHORT SCAN?

A ULTRASOUND SHORT SCAN uses the same safe sound-wave technology as any ultrasound, but:
- Duration: 5–10 minutes
- Scope: One or two targeted measurements (e.g., femur length, heart rate)
- Ideal When: You need fast reassurance between routine scans or after a borderline finding.

Types of ULTRASOUND SHORT SCAN

• Trans-abdominal: Most common; gel on the belly.
• Trans-vaginal: Higher-resolution probe if clearer images are needed.
• Doppler Add-On: Adds color flow to check umbilical or uterine artery blood supply (takes an extra 2–3 minutes).

• Fetal femur length measurement
• Amniotic fluid index (AFI)
• Placental position & grade
• Fetal presentation & heart rate

• Reassurance for parents worried about shorter femur length.
• Quick progress check between routine growth scans.
• Rule-out urgent issues such as oligohydramnios or placental insufficiency.

Common Scenarios

• Third-Trimester Checks: Doctors may order a short scan to monitor shorter-than-average femur length.
• Follow-Up: Quick reassessment after an earlier anomaly scan flagged borderline amniotic fluid.
• Emergency Triage: Bedside scan to rule-out oligohydramnios or placental abruption.

Benefits of Choosing Cadabams Diagnostics

• Fast Appointment Slots: Walk-ins and same-day online booking.
• Same-Day Results: Preliminary verbal feedback in minutes; digital report within 1 hour.
• Cost-Effective: Roughly 40 % cheaper than a full detailed scan.

Illnesses Detected

• Intra-uterine growth restriction (IUGR)
• Oligohydramnios / Polyhydramnios
• Early flags for placental insufficiency

• Hydration:
  • 20–24 weeks: 1–2 glasses of water 30 minutes before scan.
  • 28–40 weeks: Usually empty bladder—follow text instructions.
• Clothing: Two-piece outfit for easy belly access.
• Reports: Bring previous ultrasound images for comparison.

Pre-requisites

• Valid doctor’s prescription or Cadabams self-request form.
• Note of exact gestational age for correct protocol selection.
• Insurance pre-authorization if required.

Best Time to Take the Scan

• 28–40 weeks: Ideal window for femur-length surveillance.
• Any Time: When acute symptoms like decreased fetal movement occur.

Eligibility

• All pregnant individuals ≥20 weeks gestation.
• Non-pregnant patients needing focused pelvic or abdominal follow-up.

Step-by-Step Procedure

1. Check-In: Verify ID and gestation details at the front desk.
2. Positioning: Lie back on the scan couch; gel applied.
3. Quick Sweep: 5-minute targeted imaging.
4. Feedback: Wipe gel; receive verbal summary.
5. Report: Digital report sent to phone and email within 1 hour.

Important Cautions

• Inform the sonographer of latex allergy (probe covers).
• Report any vaginal bleeding or ruptured membranes.
• Skip heavy meals if you are prone to nausea.
