Ultrasound is a diagnostic imaging technique that uses high-frequency sound waves to create real-time images of organs, tissues, and blood flow inside the body. At QLD Radiology Specialists, this technology supports accurate medical assessments across a wide range of health conditions. Understanding the different types of ultrasound and their uses helps patients know what to expect and why these scans are important.
What Is an Ultrasound?
An ultrasound is a non-invasive medical scan that captures images from inside the body using sound waves instead of radiation. A transducer sends sound waves into the body, and the returning echoes form an image on a monitor.
Ultrasounds are commonly used to monitor pregnancies, assess abdominal organs, examine soft tissue injuries, and guide medical procedures. They offer clear imaging with no exposure to ionising radiation, making them safe for all age groups.
Main Types of Ultrasound
Different ultrasound types focus on specific body parts or diagnostic needs. The table below outlines key types, their features, and common uses.
| Type of Ultrasound | Features | Functions | Common Uses |
|---|---|---|---|
| Obstetric Ultrasound | Uses real-time imaging | Monitors foetal development | Pregnancy checks, growth tracking |
| Abdominal Ultrasound | Visualises internal organs | Evaluates organ structure | Liver, gallbladder, kidneys, pancreas |
| Pelvic Ultrasound | Internal or external approach | Assesses pelvic organs | Uterus, ovaries, prostate |
| Musculoskeletal Ultrasound | High-resolution soft tissue images | Examines joints, muscles, tendons | Sports injuries, inflammation |
| Vascular (Doppler) Ultrasound | Uses colour Doppler | Measures blood flow and blockages | Arteries, veins, clots |
| Echocardiogram | Heart-focused | Evaluates heart chambers and valves | Heart disease, structural issues |
| Breast Ultrasound | Detailed soft tissue images | Detects lumps and cysts | Breast screening, biopsy guidance |
Obstetric Ultrasound
Obstetric ultrasound tracks the development and health of a baby during pregnancy. It shows the baby’s heartbeat, size, movement, and position.
Features: Real-time imaging with no radiation.
Functions: Confirms pregnancy, checks growth, estimates due dates, and monitors complications.
Use Cases: First trimester dating scans, 20-week morphology scans, and late-pregnancy growth assessments.
Pros: Safe for both mother and baby, widely available, painless.
Cons: Limited detail in early weeks, sometimes requires repeat scans.
Target Audience: Pregnant individuals and their healthcare providers.
Situational Relevance: Used throughout pregnancy to monitor development.
Abdominal Ultrasound
Abdominal ultrasound creates images of organs such as the liver, kidneys, and pancreas. It detects abnormalities and helps diagnose pain or swelling.
Features: Non-invasive scan capturing soft tissue images.
Functions: Identifies organ size, structure, and blood flow patterns.
Use Cases: Detecting gallstones, kidney stones, liver disease, or abdominal masses.
Pros: No radiation, quick results, widely used in urgent care.
Cons: Limited by bowel gas, may require fasting.
Target Audience: Patients with abdominal pain, digestive symptoms, or organ disorders.
Situational Relevance: Used when physical exams are inconclusive.
Pelvic Ultrasound
Pelvic ultrasound examines reproductive and urinary organs inside the pelvis.
Features: Can be performed externally or with a transvaginal/transrectal probe.
Functions: Evaluates structures of the uterus, ovaries, bladder, and prostate.
Use Cases: Detecting ovarian cysts, uterine fibroids, or prostate enlargement.
Pros: High accuracy for soft tissues, widely available.
Cons: May cause mild discomfort, operator-dependent.
Target Audience: Individuals with pelvic pain, fertility issues, or urinary symptoms.
Situational Relevance: Used when reproductive or urinary symptoms are present.
Musculoskeletal Ultrasound
Musculoskeletal ultrasound visualises muscles, tendons, ligaments, joints, and soft tissue structures.
Features: High-resolution, real-time imaging.
Functions: Detects tears, inflammation, and fluid accumulation.
Use Cases: Sports injuries, tendonitis, bursitis, joint swelling.
Pros: No radiation, can assess movement during scan.
Cons: Operator-dependent, limited penetration in deep tissues.
Target Audience: Athletes, patients with chronic joint pain or injuries.
Situational Relevance: Used for diagnosing injuries and guiding physiotherapy.
Vascular (Doppler) Ultrasound
Vascular ultrasound uses Doppler technology to measure blood flow in arteries and veins.
Features: Colour-coded imaging of blood movement.
Functions: Detects clots, blockages, or abnormal blood flow.
Use Cases: Deep vein thrombosis, varicose veins, arterial narrowing.
Pros: Non-invasive, accurate for circulation issues.
Cons: May be less effective in very small vessels.
Target Audience: Patients with circulation problems or leg swelling.
Situational Relevance: Used before surgeries and to assess vascular conditions.
Echocardiogram
An echocardiogram is an ultrasound scan focused on the heart.
Features: Produces live images of heart chambers and valves.
Functions: Evaluates heart structure, pumping strength, and valve function.
Use Cases: Diagnosing heart disease, monitoring congenital defects, assessing heart function after illness.
Pros: No radiation, provides real-time functional data.
Cons: Limited detail of coronary arteries.
Target Audience: Patients with chest pain, heart murmurs, or known heart disease.
Situational Relevance: Used in both emergency and routine cardiac care.
Breast Ultrasound
Breast ultrasound detects lumps, cysts, or abnormal tissue changes.
Features: High-resolution images of soft tissues.
Functions: Differentiates between solid and fluid-filled masses.
Use Cases: Assessing breast lumps, guiding biopsies, screening dense breast tissue.
Pros: No radiation, accurate in dense breast tissue.
Cons: Cannot replace mammograms for detecting all cancers.
Target Audience: Patients with breast changes, especially younger individuals.
Situational Relevance: Used when mammograms show unclear results or as a first step in younger women.
Pros and Cons of Ultrasound as a Diagnostic Tool
| Pros | Cons |
|---|---|
| Safe, uses no radiation | Limited detail in deep structures |
| Real-time imaging | Operator skill impacts accuracy |
| Non-invasive and painless | Gas or bone can obstruct images |
| Widely available | May require repeat scans for clarity |
