What Is Ultrasound (Sonography)?

Ultrasound, also known as sonography or ultrasonography, is a non-invasive medical imaging technique that uses high-frequency sound waves to produce images of internal organs and tissues. These images, known as sonograms, help doctors examine different parts of the body and identify certain medical conditions.

In fertility care, ultrasound plays an important role in evaluating the reproductive organs, monitoring ovarian activity, assessing the uterus, and supporting fertility treatments. It may also be used during pregnancy to monitor the growth and development of the developing baby.

At Jyoti IVF, ultrasound examinations may be recommended as part of a fertility evaluation or treatment plan, depending on the patient’s symptoms, medical history, and clinical requirements.

What Is an Ultrasound Scan?

An ultrasound scan allows healthcare professionals to examine internal structures in real time without using ionising radiation. A handheld device called a transducer sends sound waves into the body and receives the echoes that return from different tissues. A computer processes these echoes to create images.

Ultrasound is commonly used to examine organs such as the uterus, ovaries, kidneys, thyroid gland, breasts, and abdominal organs. It can also help assess blood flow and guide certain medical procedures.

In reproductive medicine, ultrasound is particularly useful for examining the uterus and ovaries, monitoring the development of ovarian follicles, assessing the uterine lining, and guiding selected fertility procedures.

The scan is generally safe when performed by trained healthcare professionals for appropriate medical purposes.

Types of Ultrasound Scans

Different types of ultrasound examinations are used depending on the body part being examined and the medical information required.

1. 2D Ultrasound

A 2D ultrasound produces flat, two-dimensional images of internal structures. It is commonly used for routine diagnostic examinations, fertility assessments, and pregnancy scans.

2. 3D Ultrasound

A 3D ultrasound combines multiple image slices to produce a three-dimensional view of certain structures. It may help doctors assess specific anatomical features, including selected abnormalities of the uterus or fetal structures.

3. 4D Ultrasound

A 4D ultrasound produces moving three-dimensional images in real time. In pregnancy, it may be used to observe fetal movements and facial features when clinically appropriate. It is not necessary for every pregnancy.

4. Abdominal Ultrasound

An abdominal ultrasound examines organs within the abdomen, such as the liver, gallbladder, kidneys, and other structures. It may be recommended when symptoms suggest an abdominal condition.

5. Pelvic Ultrasound

A pelvic ultrasound examines organs in the pelvic region, including the uterus, ovaries, and bladder. It is frequently used in women’s reproductive healthcare and fertility investigations.

6. Transvaginal Ultrasound

A transvaginal ultrasound uses a specially designed transducer inserted gently into the vagina to obtain detailed images of the uterus, ovaries, and surrounding pelvic structures.

It is commonly used in fertility care to assess ovarian follicles, measure the uterine lining, investigate certain reproductive conditions, and monitor selected stages of fertility treatment.

7. Doppler Ultrasound

Doppler ultrasound evaluates the direction and speed of blood flow through blood vessels. It may be used in selected examinations to assess circulation and investigate certain medical conditions.

8. Breast Ultrasound

A breast ultrasound produces images of breast tissue. It may help evaluate a lump or other breast abnormality, often alongside other investigations when needed.

9. Thyroid Ultrasound

A thyroid ultrasound examines the thyroid gland and surrounding tissues. It can help assess thyroid nodules, enlargement, and other structural abnormalities.

10. Renal Ultrasound

A renal ultrasound examines the kidneys and, when necessary, related structures of the urinary system. It may be used to investigate certain kidney or urinary tract conditions.

11. Foetal Echocardiography

Foetal echocardiography is a specialised ultrasound examination that evaluates the developing baby’s heart. It is recommended in selected pregnancies when a more detailed assessment of the fetal heart is indicated.

12. Transrectal Ultrasound

A transrectal ultrasound uses a small probe inserted into the rectum to obtain images of the prostate and surrounding structures. It may be recommended for specific urological investigations.

Why Is an Ultrasound Scan Performed?

Ultrasound examinations serve several purposes, from investigating medical symptoms to monitoring pregnancy and guiding certain procedures.

1. Fertility Assessment

Ultrasound is an important tool in fertility evaluation. It helps doctors examine the uterus and ovaries and identify certain abnormalities that may affect reproductive health.

Depending on the clinical situation, an ultrasound may help assess:

• Ovarian follicles and their development.
• The thickness and appearance of the uterine lining.
• Uterine fibroids or certain structural abnormalities.
• Ovarian cysts and other ovarian findings.
• Features associated with polycystic ovary syndrome (PCOS).
• The ovaries’ response during fertility treatment.

Ultrasound findings are interpreted alongside medical history, blood tests, and other investigations. An ultrasound alone cannot identify every possible cause of infertility.

2. Pregnancy Ultrasound

Pregnancy ultrasound is used to obtain information about the developing baby and the pregnancy. Depending on the stage of pregnancy and the reason for the scan, it may help:

• Confirm the location of a pregnancy.
• Estimate gestational age.
• Assess fetal heartbeat when appropriate for the stage of pregnancy.
• Monitor fetal growth and development.
• Evaluate the placenta and amniotic fluid.
• Assess fetal position later in pregnancy.
• Investigate certain suspected pregnancy complications.

The timing and number of scans depend on clinical recommendations and the individual pregnancy.

3. Diagnostic Ultrasound

Diagnostic ultrasound helps doctors investigate symptoms and examine internal organs. It may be recommended for concerns involving the abdomen, pelvis, thyroid, breasts, kidneys, and other structures.

The scan can help identify certain abnormalities and determine whether additional tests or treatment may be needed.

4. Ultrasound-Guided Medical Procedures

Ultrasound can provide real-time images during selected medical procedures. This allows healthcare professionals to visualise the targeted area while guiding a needle or other instrument.

Depending on the procedure, ultrasound guidance may improve precision and help reduce the risk of complications.

In fertility treatment, ultrasound guidance may be used during procedures such as egg retrieval.

Who May Need an Ultrasound Scan?

An ultrasound may be recommended for people of different ages and medical backgrounds, depending on their symptoms and healthcare needs.

You may require an ultrasound if:

1. You are experiencing difficulty conceiving and need a fertility assessment.
2. You have irregular periods or symptoms that may indicate an ovarian or uterine condition.
3. Your doctor suspects conditions such as endometriosis, uterine fibroids, or ovarian cysts.
4. You are undergoing fertility treatment and require monitoring of follicular development or the uterine lining.
5. You are pregnant and need an examination to assess the pregnancy.
6. You have symptoms involving the abdomen, pelvis, thyroid, breasts, kidneys, or other organs.
7. Your doctor needs imaging guidance for a specific medical procedure.

Your healthcare provider will determine whether an ultrasound is appropriate based on your symptoms, medical history, and examination findings.

Is Ultrasound Necessary During Pregnancy?

Ultrasound is an important part of routine antenatal care, although the number and timing of scans depend on clinical recommendations and individual circumstances.

Pregnancy ultrasound may help with:

• Confirming the location and assessing the progress of a pregnancy.
• Estimating gestational age.
• Evaluating fetal growth and development.
• Assessing the placenta and amniotic fluid.
• Detecting certain structural abnormalities.
• Investigating concerns or monitoring pregnancies that require additional care.

Ultrasound cannot detect every fetal abnormality, and a normal scan does not guarantee that every aspect of fetal development is normal. Your doctor can explain which scans are recommended at each stage of pregnancy.

Are There Any Risks Associated With Ultrasound?

Diagnostic ultrasound does not use ionising radiation, unlike X-rays and CT scans. It is generally considered safe when used appropriately by trained healthcare professionals.

However, ultrasound should be performed for a valid medical reason, using appropriate settings and exposure durations. Non-medical scans solely for keepsakes or entertainment are not recommended.

Some examinations, including transvaginal ultrasound, may cause temporary discomfort. If you have concerns about the procedure, discuss them with your healthcare provider before the examination.

How to Prepare for an Ultrasound Scan

Preparation depends on the type of ultrasound being performed. Following the clinic’s instructions helps ensure that the examination produces useful images.

Before your appointment:

1. Follow the preparation instructions: Ask your healthcare provider whether you need to fast, drink water, or take any other steps before the scan.
2. Wear comfortable clothing: Loose-fitting clothes can make it easier to access the area being examined.
3. Follow bladder instructions: A full bladder may be required for some abdominal or pelvic ultrasound examinations. It is not always necessary for a transvaginal ultrasound.
4. Bring previous reports: Carry relevant medical records, laboratory results, and earlier imaging reports if requested.
5. Inform the healthcare team: Tell the staff about relevant medical conditions, symptoms, or concerns before the examination.

Do not assume that every ultrasound requires the same preparation. The instructions will vary depending on the scan.

What Happens During an Ultrasound Scan?

The procedure depends on the area being examined, but a typical external ultrasound involves the following steps.

1. Positioning

You will usually be asked to lie on an examination bed in a position that allows the healthcare professional to access the area being scanned.

2. Application of Gel

A water-based gel is applied to the skin. It helps the transducer maintain contact with the skin and allows sound waves to travel effectively.

3. Scanning

The sonographer or other qualified healthcare professional moves the transducer over the examination area to capture images from different angles. The images appear on a screen in real time.

4. Image Review

The images are recorded and reviewed according to the purpose of the examination. Depending on the findings and the type of scan, a radiologist or another qualified clinician may interpret the images and prepare a report.

5. Completion

Most ultrasound examinations are completed within approximately 15–45 minutes, although the duration varies. You can generally resume normal activities afterwards unless your healthcare provider gives different instructions.

For a transvaginal ultrasound, a specially designed covered transducer is inserted gently into the vagina. For a transrectal ultrasound, the probe is inserted into the rectum. These examinations may cause some discomfort, but they should not normally cause significant pain. Inform the healthcare professional if you experience pain or need the procedure to pause.
