If your doctor has recommended an ultrasound scan, you may be wondering why the test is needed and what it can detect. An ultrasound is a safe, painless imaging test that uses sound waves to create real-time images of internal organs, blood vessels, muscles, and a developing baby during pregnancy. Unlike X-rays and CT scans, ultrasound does not use ionising radiation, making it a preferred imaging test for many medical conditions, including pregnancy.
At Prolife Hospital Ludhiana, we provide advanced ultrasound and Colour Doppler imaging services to help doctors accurately diagnose a wide range of health conditions and monitor pregnancy with confidence.
What is an Ultrasound Scan?
An ultrasound scan, also known as sonography, is a diagnostic imaging test that uses high-frequency sound waves to produce detailed images of structures inside the body. It helps doctors evaluate organs, detect abnormalities, monitor blood flow, and assess the growth and well-being of a baby during pregnancy.
Ultrasound is widely used because it is non-invasive, painless, and provides real-time images that support accurate diagnosis and treatment planning.
Why Might Your Doctor Recommend-an Ultrasound?
Your doctor may advise an ultrasound scan to investigate symptoms or monitor specific medical conditions, including:
- Abdominal pain
- Liver or gallbladder disorders
- Kidney stones or urinary problems
- Swelling or lumps
- Thyroid conditions
- Pelvic disorders
- Pregnancy monitoring
- Breast lumps or breast pain
- Blood flow problems using Colour Doppler
- Heart evaluation through echocardiography
The type of ultrasound recommended depends on your symptoms and medical condition.
Ultrasound-During Pregnancy
Ultrasound plays an important role in monitoring the health of both the mother and the developing baby throughout pregnancy.
First Trimester Scan (11–13 Weeks)
This scan helps:
- Confirm the pregnancy
- Estimate the due date
- Check the baby’s growth
- Assess early fetal development
- Perform screening for certain chromosomal conditions when recommended by your doctor
Second Trimester Scan (18–22 Weeks)
Often called the Level II or Anomaly Scan, this examination evaluates:
- Baby’s organs
- Brain
- Heart
- Spine
- Limbs
- Placenta
- Amniotic fluid
It helps identify many structural abnormalities and monitor normal fetal development.
Third Trimester Scan (28 Weeks Until Delivery)
This scan helps assess:
- Baby’s growth
- Position of the baby
- Placental location
- Amniotic fluid levels
- Overall fetal well-being
Additional scans may be recommended if medically necessary based on your doctor’s advice.
Colour Doppler Ultrasound
Colour Doppler is an advanced ultrasound technique that evaluates the direction and speed of blood flow through blood vessels. It helps doctors diagnose conditions affecting circulation and assess blood flow to various organs.
Colour Doppler may be recommended for:
- Leg vein problems
- Arterial diseases
- Pregnancy-related blood flow assessment
- Kidney disorders
- Liver diseases
- Vascular conditions
Specialised-Ultrasound Services
Our ultrasound department also supports specialised examinations such as:
Breast Ultrasound
Breast ultrasound helps evaluate breast lumps, breast pain, cysts, and other abnormalities. It is often performed alongside mammography to provide additional information and may also assist doctors during image-guided breast biopsy procedures.
Echocardiography
Echocardiography is an ultrasound examination of the heart that evaluates:
- Heart chambers
- Heart valves
- Pumping function
- Blood flow through the heart
It is performed for adults, children, and, when indicated, unborn babies (fetal echocardiography).
How Should I Prepare for an Ultrasound?
Preparation depends on the type of ultrasound being performed.
Abdominal Ultrasound
- Do not eat for approximately 6 hours before the examination unless advised otherwise.
- Small amounts of water may be allowed if instructed by your healthcare provider.
Pelvic or Early Pregnancy Ultrasound
- A full bladder is often required for better image quality.
- Drink water before your appointment as instructed and avoid emptying your bladder until the scan is complete.
Other Ultrasound Examinations
Some scans require no special preparation. Our staff will provide specific instructions based on the type of examination you are scheduled for.
What Happens During an Ultrasound?
During the examination:
- You will lie comfortably on the examination table.
- A clear gel is applied to the skin over the area being examined.
- The sonographer gently moves a handheld device called a transducer over the skin.
- Images appear instantly on a monitor and are recorded for review.
- Most ultrasound examinations take 10 to 30 minutes, depending on the body part being evaluated.
The procedure is painless and you can usually return to your normal activities immediately afterwards.
Is an Ultrasound Safe?
Yes. Ultrasound has been used safely for many years and does not involve exposure to ionising radiation. When performed for appropriate medical reasons by trained healthcare professionals, it is considered a safe imaging method for adults, children, and pregnancy.

Frequently-Asked Questions
Is an ultrasound painful?
No. Ultrasound is a painless, non-invasive procedure. You may feel slight pressure from the transducer, but it should not be painful.
Why has my doctor advised an ultrasound?
Ultrasound helps doctors examine internal organs, monitor pregnancy, investigate pain or swelling, detect abnormalities, and guide further treatment.
Does ultrasound use radiation?
No. Ultrasound uses sound waves and does not expose you to ionising radiation.
How long does an ultrasound take?
Most ultrasound examinations take between 10 and 30 minutes, although some specialised scans may take longer.
Do I need to fast before my ultrasound?
Some abdominal ultrasound examinations require fasting, while others do not. Follow the preparation instructions provided by your healthcare team.
Why do I need a full bladder for some ultrasound scans?
A full bladder helps improve image quality during certain pelvic and early pregnancy ultrasound examinations, allowing the doctor to evaluate the area more clearly.
Can ultrasound detect cancer?
Ultrasound can identify abnormal lumps or changes in tissues, but additional investigations such as biopsy, mammography, CT scan, or MRI may be required to confirm a diagnosis.
When will I receive my ultrasound report?
Your ultrasound images will be reviewed by a radiologist, and the findings will be shared with your treating doctor, who will explain the results and discuss any further evaluation or treatment if required.
