What Is an Ultrasound Scan?

An ultrasound scan is a non-invasive diagnostic imaging examination that uses high-frequency sound waves to produce images of structures inside the body.

A small device called a transducer is moved over the skin, usually with ultrasound gel between the transducer and the skin. The sound waves travel into the body and return as echoes. The ultrasound system processes these echoes to create images.

Ultrasound can provide real-time imaging and may be used to examine:

• Abdominal organs
• Pelvic structures
• Urinary system
• Thyroid and other superficial structures
• Soft tissues
• Blood flow through vessels
• Pregnancy and fetal development when medically indicated

The type of ultrasound depends on the clinical question your doctor needs to answer.

The decision may depend on:

• Your symptoms
• Medical history
• Physical examination
• Previous test results
• Body area requiring evaluation
• Suspected condition
• Need for follow-up imaging

Ultrasound may be useful for evaluating selected conditions involving the abdomen, pelvis, urinary system, thyroid, soft tissues, blood vessels and pregnancy.

Your doctor will determine whether ultrasound is appropriate for your particular situation.

What Areas of the Body Can an Ultrasound Scan Examine?

Ultrasound can be used for different parts of the body depending on the examination requested.

Abdominal Ultrasound

An abdominal ultrasound can provide images of abdominal organs such as the:

• Liver
• Gallbladder
• Kidneys
• Pancreas
• Spleen
• Major abdominal blood vessels

The exact organs examined depend on the prescribed examination.

Pelvic Ultrasound

Pelvic ultrasound can be used to examine structures within the pelvis.

Depending on the patient and clinical requirement, different approaches may be used, including abdominal or other specialized pelvic ultrasound techniques.

Urinary System Ultrasound

Ultrasound may be used to examine structures such as the:

• Kidneys
• Urinary bladder
• Related urinary structures

Thyroid and Neck Ultrasound

Ultrasound can provide detailed images of superficial structures such as the thyroid and selected tissues in the neck.

Soft-Tissue Ultrasound

Ultrasound may be used to evaluate selected superficial soft tissues, depending on the clinical concern.

Breast Ultrasound

Breast ultrasound may be recommended in selected situations to evaluate breast tissue and specific areas of concern.

It may be used as a complementary examination depending on the clinical situation and other breast imaging findings.

Vascular and Doppler Ultrasound

Doppler ultrasound can be used to assess blood flow through blood vessels. Ultrasound can provide real-time information about blood flow and may be used for selected vascular examinations.

What Is Doppler Ultrasound?

Doppler ultrasound is an ultrasound technique used to evaluate blood flow through blood vessels.

It can provide information about:

• Direction of blood flow
• Movement of blood
• Blood-flow patterns
• Selected abnormalities affecting blood vessels

Doppler techniques may be incorporated into an ultrasound examination when clinically appropriate.

The specific type of Doppler examination depends on the body part and the clinical question.

What Is an Ultrasound Scan Used For?

Ultrasound has a wide range of diagnostic applications.

Depending on the type of examination, it may help evaluate:

• Abdominal pain
• Pelvic symptoms
• Certain urinary symptoms
• Selected soft-tissue abnormalities
• Thyroid abnormalities
• Fluid-filled structures
• Certain vascular conditions
• Pregnancy-related findings

Ultrasound can also be used to guide some minimally invasive procedures, such as selected needle biopsies or fluid aspiration, when clinically appropriate.

An ultrasound scan does not provide a diagnosis by itself. The images and findings need to be interpreted in the context of your symptoms, medical history and other clinical information.

How Does an Ultrasound Scan Work?

Ultrasound uses sound waves rather than X-rays to create images.

During a typical examination:

1. Ultrasound gel is applied to the skin.
2. The transducer is placed over the examination area.
3. Sound waves travel into the body.
4. The returning echoes are detected by the transducer.
5. Computer processing converts the information into images.

Because ultrasound produces images in real time, the examiner can observe certain movements and blood-flow patterns during the examination.

What Happens During an Ultrasound Scan?

An ultrasound examination is generally straightforward and does not usually require invasive procedures.

1. Preparation

Your preparation depends on the body part being examined.

2. Positioning

You will be asked to lie or sit in a position that allows the area to be examined properly.

3. Applying Ultrasound Gel

A small amount of gel is applied to the skin. The gel helps the transducer move smoothly and allows sound waves to travel effectively into the body.

4. Scanning

The sonographer or appropriately trained healthcare professional moves the transducer across the area being examined.

You may be asked to:

• Change position
• Take a breath
• Hold your breath briefly
• Drink water before the scan
• Have a full bladder for certain examinations

The instructions depend on the type of ultrasound.

5. Image Review

Images are obtained during the examination and form part of the diagnostic assessment.

How Should You Prepare for an Ultrasound Scan?

Ultrasound preparation depends on the type of examination. Some ultrasound scans require little or no preparation, while others may require fasting or a full bladder.

For Abdominal Ultrasound

You may be given instructions about fasting or food intake before the examination, depending on the specific abdominal scan.

For Pelvic Ultrasound

You may be asked to drink water before the examination so that your bladder is adequately filled, depending on the examination protocol.

For Other Ultrasound Examinations

Some examinations may require no special preparation.

Before Your Appointment

Contact the centre and confirm the specific preparation instructions for your ultrasound rather than following generic advice found online.

Is an Ultrasound Scan Safe?

Diagnostic ultrasound is considered safe when appropriately used and does not use ionizing radiation.

This is one reason ultrasound is widely used in different patient groups and during pregnancy when medically indicated.

However, ultrasound should still be used appropriately for a clinical purpose rather than performed unnecessarily.

During pregnancy, professional guidance recommends prudent use by appropriately trained healthcare professionals and keeping exposure as low as reasonably achievable while obtaining the required diagnostic information.

Does an Ultrasound Scan Use Radiation?

No. Ultrasound does not use ionizing radiation.

Ultrasound uses high-frequency sound waves to create images.

This makes it different from:

• X-Ray → Uses X-rays
• CT Scan → Uses X-rays
• MRI → Uses magnetic fields and radio waves

Because ultrasound does not use ionizing radiation, it is commonly used for examinations where repeated imaging may be needed and is also widely used during pregnancy when clinically appropriate.

Is an Ultrasound Scan Painful?

Most ultrasound examinations are non-invasive and are usually painless.

You may feel some pressure as the transducer moves over the skin, particularly when the examiner needs to obtain images from a particular area.

Some examinations may cause temporary discomfort depending on the body part being examined or the underlying condition.

Tell the healthcare professional if you experience significant discomfort during the examination.

Is Ultrasound Used During Pregnancy?

Yes. Ultrasound is widely used during pregnancy to assess the developing fetus and pregnancy-related structures when medically indicated.

What Are the Benefits of Pregnancy Ultrasound?

• Fetal development
• Fetal anatomy
• Pregnancy location
• Fetal growth
• Placental position
• Amniotic fluid
• Other pregnancy-related findings

The type and timing of an obstetric ultrasound depends on the pregnancy and the clinical reason for the examination.

Important

Ultrasound during pregnancy should be performed for an appropriate medical purpose by appropriately trained professionals. Non-medical fetal scanning purely for keepsake images is discouraged by the American Institute of Ultrasound in Medicine.

What Is the Difference Between Ultrasound and Doppler Ultrasound?

Both examinations use ultrasound technology, but they provide different types of information.

A Doppler study may be included as part of an ultrasound examination when clinically appropriate.

Ultrasound vs CT Scan – What Is the Difference?

Ultrasound and CT use different technologies and are selected for different clinical purposes.

Is Ultrasound Better Than CT?

Neither ultrasound nor CT is universally better.

The appropriate examination depends on:

• Symptoms
• Body part
• Suspected condition
• Medical history
• Clinical question
• Information required by the doctor

Your doctor may recommend ultrasound, CT, MRI, X-ray or another examination depending on your individual situation.

Can Ultrasound Detect Everything?

No. Ultrasound is a valuable diagnostic tool, but it has limitations.

Ultrasound does not provide equally useful images of every body structure.

For example, sound waves can be affected by:

• Air or gas
• Bone
• Body size and tissue depth
• Patient movement
• The location of the structure being examined

Ultrasound is generally less suitable for imaging air-filled lungs and cannot pass through bone to visualize structures beyond it in the same way as CT or MRI.

If ultrasound does not answer the clinical question, your doctor may recommend another imaging examination.

What Happens After an Ultrasound Scan?

After the examination, the images and findings are reviewed as part of the diagnostic process.

The interpretation may be considered together with:

• Your symptoms
• Medical history
• Clinical examination
• Previous test results
• Other imaging studies

Your doctor can explain the findings and advise whether further investigation or follow-up is required.

In some situations, another imaging examination may be recommended if additional information is needed.

Do not interpret ultrasound images on your own or assume that an image automatically confirms a particular condition.
