Ultrasound Imaging

Ultrasound Imaging

Ultrasound imaging is a widely used diagnostic imaging technique that uses high-frequency sound waves to create real-time images of structures inside the body. Also known as sonography or diagnostic ultrasound, it can help doctors evaluate organs, tissues, blood vessels and other areas of the body as part of a clinical assessment.

At Siris Healthcare, ultrasound imaging can support the evaluation of a wide range of health concerns. Depending on the area being examined and the doctor's recommendation, an ultrasound scan may be used to assess the abdomen, pelvis, thyroid, breast, urinary system, pregnancy-related structures and blood flow through vessels.

What Is an Ultrasound Scan?

An ultrasound scan uses a handheld device called a transducer to send sound waves into the body. The returning echoes are processed to produce images that can be viewed in real time.

Unlike imaging methods that use ionizing radiation, ultrasound uses sound waves. It is therefore commonly used when doctors need dynamic images of soft tissues, organs or blood flow. The type of ultrasound recommended depends on the patient's symptoms, medical history and the clinical question that needs to be answered.

Types of Ultrasound Imaging

Different ultrasound examinations are designed to evaluate different parts of the body. Common types include:

Abdominal Ultrasound

An abdominal ultrasound can help examine organs and structures such as the liver, gallbladder, pancreas, spleen and kidneys. Doctors may recommend this scan when evaluating symptoms such as abdominal discomfort or when they need to investigate a suspected abnormality.

Pelvic Ultrasound

A pelvic ultrasound is used to examine structures within the pelvic region. Depending on the patient's age, symptoms and clinical requirements, it may be performed using an external approach or another technique recommended by the healthcare professional.

Pregnancy Ultrasound

Pregnancy ultrasound is commonly used during pregnancy to assess fetal development, growth, position and other pregnancy-related findings. The timing and type of scan depend on the stage of pregnancy and the recommendation of the treating healthcare professional.

Doppler Ultrasound

Doppler ultrasound evaluates blood flow through blood vessels. It can help healthcare professionals assess the direction and characteristics of blood flow and investigate certain vascular concerns.

Thyroid Ultrasound

A thyroid ultrasound provides detailed images of the thyroid gland and can help evaluate thyroid nodules, cysts and other structural changes. Further tests may be recommended depending on the findings and clinical assessment.

Breast Ultrasound

A breast ultrasound uses sound waves to create images of breast tissue. It may be recommended to evaluate a particular area of concern or as a complementary examination alongside other breast imaging, depending on the patient's age and clinical situation.

Why Might a Doctor Recommend an Ultrasound?

An ultrasound examination may be recommended for several reasons, including:

• Investigating unexplained pain or discomfort
• Evaluating an abnormal lump or swelling
• Examining abdominal or pelvic organs
• Assessing the thyroid or other soft tissues
• Evaluating blood flow with Doppler imaging
• Monitoring certain conditions over time
• Supporting pregnancy-related assessment
• Further evaluating a finding identified during a physical examination or another diagnostic test

An ultrasound does not by itself provide a complete diagnosis in every situation. The images are interpreted along with the patient's symptoms, medical history, physical examination and other relevant investigations.

How Should You Prepare for an Ultrasound Scan?

Ultrasound preparation depends on the type of examination being performed. Some scans may require fasting for a specific period, while others may require a comfortably full bladder.

Patients should follow the preparation instructions provided for their particular examination. If you are unsure whether you need to fast, drink water or make any other preparation, confirm the instructions with the healthcare team before your appointment.

What Happens During an Ultrasound?

During an ultrasound examination, the patient is generally positioned so that the area being examined is accessible. A small amount of ultrasound gel may be applied to the skin, and the sonographer or healthcare professional moves the transducer over the examination area to capture images.

The procedure is generally straightforward, although some examinations may involve mild pressure or temporary discomfort depending on the body area being assessed.

The duration of an ultrasound scan varies according to the type of examination and the information required.

Are Ultrasound Scans Safe?

Ultrasound imaging uses sound waves rather than ionizing radiation. It has been used extensively in medical diagnosis, including during pregnancy, when performed appropriately by trained healthcare professionals.

As with any medical examination, the appropriate type of imaging and its use should be determined according to the patient's individual clinical needs.

What Happens After the Scan?

After the examination, the acquired images are reviewed and interpreted by an appropriately qualified medical professional, such as a radiologist, when applicable. The findings are documented in a report and shared according to the healthcare provider's process.

Your doctor may recommend additional tests or follow-up depending on the ultrasound findings and your overall clinical condition.

When Should You Consider an Ultrasound?

If your doctor has recommended an ultrasound or you are experiencing symptoms that may require diagnostic imaging, the appropriate examination should be selected based on your medical history and clinical needs.

Whether you need an abdominal ultrasound, pelvic ultrasound, thyroid ultrasound, pregnancy ultrasound or Doppler ultrasound, the healthcare team can guide you on the appropriate examination and preparation requirements.

Ultrasound Imaging at Siris Healthcare

Siris Healthcare provides access to diagnostic healthcare services with an emphasis on clear communication and patient-focused care. If you have been advised to undergo an ultrasound scan, speak with your healthcare provider about the type of examination required, preparation instructions and what to expect during the procedure.

An ultrasound is a diagnostic tool, and its findings should always be interpreted in the context of your symptoms, medical history and advice from your treating healthcare professional.
