An ultrasound is a non-invasive imaging examination that uses high-frequency sound waves to create real-time images of structures inside the body. Unlike X-rays and CT scans, it does not use ionising radiation. Depending on the examination, Doppler imaging can also provide information about blood flow.
An abdominal ultrasound helps doctors examine important organs and structures within the abdomen, including the liver, gallbladder, kidneys, pancreas, spleen, bile ducts and abdominal blood vessels. An abdominal ultrasound scan may be recommended for abdominal pain, swelling, unexplained symptoms or certain abnormal test results. It can provide useful information about the size, shape and appearance of these organs.
What Can an Abdominal Ultrasound Detect?
An abdominal organ ultrasound can help identify structural changes and findings such as gallstones, kidney stones, organ enlargement and certain abnormalities involving the abdominal aorta. The liver, pancreas and spleen can also be assessed. However, ultrasound cannot detect every medical condition, and bowel gas, body structure and deeper organs can sometimes affect image quality.
Key organs commonly examined include:
- Liver: Size, shape and structural appearance
- Gallbladder: Gallstones and other abnormalities
- Kidneys: Stones and structural changes
- Pancreas: Visible portions and structural findings
- Spleen: Size and appearance
- Bile ducts: Certain changes or blockages
- Abdominal aorta: Size and appearance
- Blood vessels: Blood flow when Doppler is required
What Is a Transabdominal Ultrasound?
A transabdominal ultrasound is performed by placing an ultrasound transducer on the outside of the abdomen. A special gel is applied to the skin to help sound waves travel between the transducer and the body. The returning echoes are converted into images for examination.
A transabdominal scan can also be used for certain pelvic examinations. Depending on the clinical requirement, a pelvic ultrasound may assess structures in the lower abdomen and pelvis. The appropriate approach depends on what the doctor needs to evaluate.
When Is an Abdominal Ultrasound Recommended?
Doctors may recommend an ultrasound when they need additional information about abdominal symptoms or a suspected condition. Common reasons include:
- Persistent or unexplained abdominal pain
- Abdominal swelling or discomfort
- Suspected gallstones or kidney stones
- Abnormal liver-related blood test results
- Changes in an abdominal organ
- Evaluation of certain blood-vessel abnormalities
- Monitoring a previously identified finding
An ultrasound is an important diagnostic tool, but it does not always provide a final diagnosis on its own. The radiologist’s findings are considered alongside symptoms, medical history, examination and other test results.
How Is the Scan Performed?
During an USG abdomen examination, the patient generally lies on an examination table. The sonographer applies gel to the required area and gently moves the transducer across the skin. The patient may be asked to change position, take a deep breath or briefly hold their breath to obtain clearer images.
The examination is generally comfortable and does not involve needles or injections. Some pressure may be felt if the transducer passes over a sensitive area. Routine ultrasound usually does not require a recovery period.
How Should You Prepare?
Preparation depends on the type of ultrasound. Some abdominal examinations may require fasting, while certain pelvic examinations may require a comfortably full bladder. Patients should follow the specific instructions provided by their doctor or diagnostic centre.
Following preparation instructions can help support clearer imaging. When appropriate, patients can also bring previous imaging reports so the radiologist can compare earlier findings with the current examination.
Is Abdominal Ultrasound Safe?
Abdominal sonography is generally considered a safe, non-invasive imaging method because it uses sound waves rather than ionising radiation. It provides real-time images and can be used for different examinations according to the patient’s needs.
Although ultrasound is useful, it is not the right test for every medical condition. If the images do not provide sufficient information, the doctor may recommend another imaging examination or follow-up.
Understanding Your Ultrasound Report
An ultrasound report describes the structures examined and the observations made during the scan. Medical terminology can sometimes be difficult for patients to understand, so individual findings should not be interpreted without considering the complete report and medical history.
If additional testing is recommended, it does not necessarily mean that a serious condition has been confirmed. Further evaluation may simply be required to understand an unclear finding more accurately.
