Scan-specific guidance on when each ultrasound is done and what to expect.
1. What is an early pregnancy (viability) scan and when is it done?
Usually done around 6-8 weeks to confirm intrauterine pregnancy, fetal heartbeat, number of fetuses and approximate gestational age.
2. When is the dating/first trimester scan done?
Usually between 10-13 weeks to confirm expected due date and basic early fetal assessment. Timing can vary based on last menstrual period certainty.
3. When is NT scan done and what does it assess?
NT scan is typically done between 11 weeks and 13 weeks + 6 days. It assesses nuchal translucency and early markers used with blood tests for chromosomal risk screening.
4. When is anomaly scan done and what should I expect?
Usually done around 18-22 weeks to evaluate fetal anatomy (brain, spine, heart, abdomen, kidneys, limbs), placenta, fluid and cervix. The scan usually takes longer than routine scans.
5. What is a growth scan and when is it done?
Growth scans are commonly done in the third trimester (often around 28, 32 and 36 weeks when indicated) to track fetal growth, fluid level and placental status.
6. What is a Doppler scan and who needs it?
Doppler evaluates blood flow in fetal and placental vessels. It is recommended in high-risk pregnancy such as growth restriction, hypertension or suspected placental insufficiency.
7. What is a biophysical profile (BPP) scan?
BPP combines ultrasound parameters (fetal movements, tone, breathing, amniotic fluid) and sometimes NST to assess fetal wellbeing in late pregnancy or high-risk cases.
8. What is pelvic ultrasound and when is it advised?
Pelvic scan is used for period issues, fibroids, ovarian cysts, pelvic pain and bleeding problems. It can be transabdominal or transvaginal based on indication.
9. What is transvaginal scan (TVS) and is it painful?
TVS gives clearer pelvic detail and early pregnancy imaging. It is generally well tolerated with mild discomfort, not severe pain, and is done with privacy-focused protocol.
10. What is follicular monitoring and when is it done?
Follicular monitoring is a series of scans in fertility treatment, usually starting early in cycle and repeated every few days to track follicle growth and ovulation timing.
11. Do I need a full bladder for ultrasound?
For many transabdominal pelvic/early pregnancy scans, a full bladder improves visibility. For transvaginal scans, bladder is usually emptied before scan.
12. How should I prepare and what reports will I get?
Carry previous reports and prescriptions. Preparation depends on scan type. You receive a structured report with findings and next-step guidance from the treating doctor.
