At Aligarh Diagnostic Center, we answer this question for hundreds of excited and anxious parents in Aligarh every month. In this guide, I’ll walk you through exactly which scans doctors worldwide consider the best and safest throughout pregnancy, why they stand out, and when other scans might be used. Think of it as a calm, honest conversation between friends.
Pregnancy scans give you that magical first look at your baby while checking growth, position, and health. If you’re searching for “which scan is best for pregnancy” or need a trusted center in Aligarh, you’ve come to the right place. The short answer? Ultrasound is the best and safest scan throughout all three trimesters. Let’s see why.
Why Is Ultrasound the Best and Safest Scan in Pregnancy?
Ultrasound has been the gold standard for over 40 years because:
- It uses simple sound waves — no ionizing radiation (unlike CT or X-ray)
- No known harm to mother or baby in over five decades of use
- Real-time images let you see the baby move and hear the heartbeat
- Can be done as often as medically needed
- Affordable and widely available
Every major health body — WHO, the American College of Obstetricians and Gynecologists (ACOG), the Indian Society of Obstetricians, and NHS — agrees: ultrasound is the first-choice and only routine imaging method during a healthy pregnancy.
The Main Pregnancy Scans (All Ultrasound-Based)
1. Dating / Viability Scan (6-10 weeks)
Confirms pregnancy is inside the uterus, sees the heartbeat (as early as 6 weeks), and gives the accurate due date.
2. NT Scan (11-13+6 weeks)
Measures fluid at the baby’s neck to assess risk for Down syndrome and major heart defects.
3. Anomaly Scan / Level II (18-22 weeks)
The most detailed scan checks the brain, spine, heart, kidneys, limbs, face, and placenta. This is the single most important routine scan of the pregnancy.
4. Growth & Wellbeing Scans (28-40 weeks)
Monitors baby’s size, amniotic fluid, blood flow in the umbilical cord, and placenta position.
5. Special Scans (when needed)
- Doppler studies for blood flow issues
- Cervical length for preterm birth risk
- 3D/4D for better facial views (purely optional)
All of these are ultrasound — safe, painless, and effective.
When Are Other Scans Ever Used in Pregnancy?
- MRI (second or third trimester only): Used rarely when ultrasound is unclear — for example, complex brain abnormalities, placental problems, or maternal conditions. MRI is considered safe after the first trimester because it has no radiation.
- CT scan: Rarely used because of radiation. Only in life-threatening emergencies (severe trauma) and even then, with heavy shielding.
- X-ray: Avoided unless necessary (e.g., suspected broken bone) and done with lead shielding over the belly.
So, for 99.9 % of pregnancies, an ultrasound is the only scan you’ll ever need.
The Ultrasound Procedure During Pregnancy: What to Expect
Here’s exactly how it goes at Aligarh Diagnostic Center:
Preparation
- First trimester: Come with a comfortably full bladder (helps lift the uterus)
- Second & third trimester: Empty bladder is fine
- Wear something loose and two-piece
During the Scan
You lie on a comfortable bed, warm gel is applied to your belly, and the sonologist gently moves a small probe. You can watch the screen the whole time — most parents say it’s an emotional, beautiful moment.
Duration
- Early scans: 10-20 minutes
- Anomaly scan: 30-45 minutes
After the Scan
Wipe off the gel, get beautiful printouts or digital pictures, and receive a detailed report within hours through our portal.
Our rooms are private, clean, and we encourage partners or family to join and share the joy.
Benefits of Ultrasound in Pregnancy
- Completely safe for mother and baby
- Real-time moving images and heartbeat sound
- Accurate dating and growth tracking
- Early detection of major abnormalities
- Helps plan delivery (breech, placenta position)
- Emotional bonding — that first smile or yawn is priceless
MRI in Pregnancy: When It’s Used and Why It’s Still Safe
Although ultrasound is enough for almost everyone, fetal MRI is increasingly used in tertiary centers when the anomaly scan shows something complex (brain, spine, chest, or abdominal wall defects). It is done after 18 weeks and provides incredible detail that ultrasound sometimes can’t because of the baby’s position or maternal body habitus.
Common neurological conditions diagnosed with fetal MRI:
- Ventriculomegaly and brain malformations
- Corpus callosum agenesis
- Neural tube defects (spina bifida details)
- Posterior fossa abnormalities
- Cortical development problems
Our 1.5 Tesla MRI is fully capable of gentle, non-contrast fetal imaging when referred by your obstetrician.
