Sonography, commonly known as an ultrasound scan, is a safe and effective diagnostic technique that uses sound waves to produce live images of internal body structures. The images created through this process are called sonograms.
Ultrasound scans play a vital role in diagnosing medical conditions, guiding medical procedures, and monitoring the growth and development of a foetus during pregnancy. At Naarayani, ultrasound examinations are performed by trained and experienced professionals to ensure accuracy, comfort, and safety. Ultrasounds are generally considered safe, and patients are encouraged to discuss any concerns with their doctor.
Ultrasound technology can be used in various ways depending on the medical requirement. Common types include:
Produces flat, two-dimensional black-and-white images of internal organs and structures.
Creates three-dimensional still images that provide detailed views of organs and tissues, helping in the detection of tumours or structural abnormalities.
Similar to 3D ultrasound but shows live movement. It is useful for observing foetal movements, blood flow, and organ activity.
Used to examine organs within the abdomen such as the liver, gallbladder, pancreas, and spleen.
Helps evaluate breast tissues and detect lumps or abnormalities.
Measures blood flow through blood vessels and helps detect blockages or circulation issues.
A specialised ultrasound used to examine the heart of a developing foetus and detect structural heart defects.
Produces images of the kidneys and urinary tract to diagnose kidney-related conditions.
Examines pelvic organs including the uterus, ovaries, bladder, and prostate.
Evaluates the thyroid gland and surrounding tissues to diagnose thyroid disorders.
Involves inserting a probe into the rectum to assess the prostate gland.
A probe is inserted into the vagina to obtain detailed images of the uterus, ovaries, and reproductive organs and to confirm or monitor pregnancy.
Ultrasound scans are used across many medical specialties and not just during pregnancy. Common uses include:
Used to confirm pregnancy and monitor foetal heart rate, growth, position, amniotic fluid levels, and detect possible birth defects.
Helps evaluate internal organs such as the thyroid, kidneys, abdomen, breasts, prostate, and pelvic organs to diagnose medical conditions.
Ultrasound guidance provides real-time imaging during procedures like biopsies, injections, drainages, and minimally invasive surgeries, improving precision and safety.
An ultrasound scan may be recommended for:
Women facing fertility issues to assess the uterus and ovaries
Women with conditions such as endometriosis, fibroids, or ovarian cysts
Patients with abdominal, kidney, thyroid, heart, pelvic, or prostate issues
Patients undergoing procedures like laparoscopy, biopsies, or guided injections
Doctors at Naarayani evaluate medical history and symptoms before recommending an ultrasound.
While ultrasound is not mandatory, it is highly recommended as part of routine prenatal care due to its many benefits, including:
Confirming pregnancy
Monitoring foetal growth and development
Detecting complications early
Managing high-risk pregnancies
Assessing amniotic fluid levels
Determining foetal position
Ultrasound is a non-invasive and safe procedure with no known harmful effects on the mother or the foetus. Unlike X-rays or CT scans, it does not use radiation. If patients have concerns, they should discuss them with their healthcare provider before the scan.
To prepare for an ultrasound scan:
Follow all instructions provided by your healthcare provider
Wear loose and comfortable clothing
You may be asked to drink water and avoid urinating before certain scans (especially pregnancy or pelvic ultrasounds)
Carry previous reports or referral documents, if applicable
During the procedure:
You will lie comfortably on an examination table
A gel will be applied to the area being examined to help transmit sound waves
The sonographer moves a transducer over the area to capture live images
The procedure is painless and usually takes 15–45 minutes
For transvaginal or transrectal ultrasounds, a small probe is gently inserted into the vagina or rectum, which may cause mild discomfort.
After the scan, the doctor will review and explain the results.
Sonography is a safe, reliable, and essential diagnostic tool used to monitor pregnancy, diagnose medical conditions, and guide procedures. With advanced technology and expert care, Naarayani ensures accurate ultrasound imaging and compassionate patient experience.
