Appendicitis Ultrasound Scan
Private Appendicitis Ultrasound Scan
£219
When you’re experiencing sudden, sharp pain in your lower right abdomen, nausea, or a fever, appendicitis might be the cause. Left untreated, it can lead to serious complications. An ultrasound scan offers a fast, safe way to assess whether your appendix is inflamed and whether more urgent action is needed.
What Is Appendicitis
The appendix is a small, tube-like organ attached to the large intestine. Appendicitis occurs when this appendix becomes inflamed, often due to a blockage or infection. Typical signs include pain around the belly button that moves to the lower right abdomen, loss of appetite, nausea, vomiting, fever, and sometimes changes in bowel habits. Because the appendix is tucked away and small, diagnosis can sometimes be tricky.
Why Use Ultrasound for Diagnosis
Ultrasound is usually the first imaging option if appendicitis is suspected, especially in people wanting to avoid radiation exposure or where CT scans are less preferable. Some key advantages:
Non-invasive and no radiation – uses sound waves, not X-rays or CTs, making it safer
Speed – provides real-time imaging, so decisions can often be made quickly
Effectiveness – can reveal inflammation, fluid, thickening of the appendix wall, or other signs consistent with appendicitis
Helps rule out other causes – also checks surrounding organs to see if something else is the culprit
That said, ultrasound is quite operator-dependent. If the appendix is difficult to visualise due to bowel gas, obesity, or its position, results may be inconclusive. In those cases, further imaging or clinical monitoring may be needed.
Who Should Get an Appendicitis Scan
You might be advised to have an appendicitis ultrasound scan if you are experiencing one or more of the following:
Pain in the lower-right side of your abdomen, or pain that moves from your mid-abdomen
Fever or chills
Loss of appetite, nausea, or vomiting
Digestive upset such as constipation, diarrhoea, or bloating
Abnormal blood test markers, such as a raised white blood cell count
If the exact cause of abdominal pain is unclear, an ultrasound can help confirm or rule out appendicitis before deciding on surgery or further treatment.
What to Expect During the Scan
Medical history and symptoms review – you’ll be asked about your pain, when it started, and other related symptoms
Positioning – you’ll lie on your back on the scan bed
Gel and probe application – a water-based gel is applied to your abdomen while a sonographer uses a handheld probe to send sound waves
Imaging the appendix – the sonographer looks for signs of inflammation, swelling, or fluid and checks surrounding tissues and organs
Consultation and reporting – you will usually receive verbal feedback during or immediately after the scan, followed by a written report
The scan typically takes around 20 minutes. Preparation is minimal, though fasting for a few hours beforehand can help produce clearer images. A full bladder may be requested in female patients to help visualise the area.
What Happens After the Scan
Depending on the results:
If appendicitis is confirmed – you may be referred urgently for treatment or surgery
If complications are visible – additional treatment such as antibiotics, drainage, or surgical planning may be required
If inconclusive – your symptoms may be monitored, or additional tests carried out
You will receive verbal findings on the day and a full written report shortly after. If urgent action is needed, this will be explained clearly.
Frequently Asked Questions
Will the scan hurt?
No. You may feel slight pressure on tender areas, but the scan itself is painless.
Do I need to see my GP first?
No. You can book directly without a referral.
Can ultrasound alone rule out appendicitis?
Not always. While highly accurate in many cases, further imaging or observation may be required if the scan is inconclusive.
How quickly will I get results?
You will usually receive verbal feedback immediately after the scan and a written report the same day.
