Focused right lower abdominal ultrasound • London & St Albans
Private appendicitis ultrasound scan
A focused, radiation-free ultrasound assessment of the appendix and right lower abdomen for clinically stable patients with localised pain or suspected inflammation. The examination can identify sonographic features that support appendicitis, but an inconclusive scan cannot safely exclude it.
- No ionising radiation
- Focused appendix assessment
- Written report and images
- Urgent escalation when indicated
Direct answer
Can ultrasound detect appendicitis?
Ultrasound can detect appendicitis when the appendix is clearly visualised and demonstrates characteristic inflammatory changes. The practitioner may assess appendix diameter, compressibility, wall appearance, local tenderness, surrounding fat, fluid, an appendicolith and increased blood flow.
However, the appendix is not always visible because of bowel gas, body habitus, its position or discomfort limiting pressure. A non-visualised appendix or apparently normal scan does not reliably rule out appendicitis. Ongoing symptoms may require urgent clinical examination, blood and urine tests, observation, CT or MRI.
This ultrasound is an imaging test, not an emergency service or a stand-alone diagnosis. Suspected appendicitis requires clinical assessment, and severe or worsening symptoms should be evaluated urgently in hospital.

Scan coverage
What is assessed during the £219 appointment?
The examination is focused on the right lower abdomen and tailored to your symptoms, clinical history and technical visibility.
Appendix visualisation
The practitioner searches for the appendix using graded compression and documents whether it is fully, partly or not visualised.
Size and compressibility
A visible appendix may be measured and assessed for abnormal enlargement, wall thickening and failure to compress.
Local inflammatory signs
Assessment may include surrounding echogenic fat, local fluid, hyperaemia and focal tenderness under the probe.
Appendicolith or collection
The scan may demonstrate a calcified appendicolith, peri-appendiceal fluid or a visible collection where present.
Adjacent bowel and tissues
Accessible bowel loops, mesentery, lymph nodes and surrounding soft tissues are reviewed for visible alternative or associated findings.
Alternative visible causes
Depending on sex, anatomy and preparation, ultrasound may identify another visible cause of right lower abdominal pain, but the scan is not a full abdominal or pelvic examination.
Symptoms and referrals
When might an appendix ultrasound be considered?
- Localised pain or tenderness in the right lower abdomen
- Pain that began centrally and moved to the lower right side
- Pain worsened by movement, coughing or gentle pressure
- Nausea, vomiting, loss of appetite or low-grade fever
- Raised inflammatory markers or white blood cell count
- Clinical concern about appendicitis where ultrasound is considered appropriate
- Need to avoid ionising radiation, including selected younger or pregnant patients under clinical guidance
- Assessment for another visible cause of focal right lower abdominal pain
Before your appointment
How to prepare for an appendix ultrasound
Preparation depends on your symptoms and whether additional pelvic views may be needed. Follow the exact instructions in your booking confirmation.
Follow fasting advice
You may be asked not to eat for several hours before the scan to reduce bowel contents and gas. Small sips of water and essential medication may be permitted unless advised otherwise.
Bladder instructions
Some patients may be asked to arrive with a comfortably full bladder, particularly if pelvic structures may need assessment. Use the exact volume and timing provided.
Bring clinical information
Bring recent blood, urine or pregnancy-test results, medication details, referral information and previous CT, MRI or ultrasound reports if available.
Do not delay urgent care
Do not wait to fast, fill your bladder or attend a booked scan if pain becomes severe, spreads, or is accompanied by collapse, confusion or breathing difficulty.
Your appointment
What happens during the scan?
The examination is non-invasive and uses a handheld probe over the abdomen.
- 1
History and safety review
The practitioner asks where the pain began, how it has changed, associated symptoms, pregnancy possibility, previous surgery, medicines and any test results.
- 2
Right lower abdominal examination
You usually lie on your back. Gel is applied and the practitioner scans the right lower abdomen, often using gradual graded compression to move bowel gas and assess tenderness.
- 3
Appendix and surrounding tissues
The visible appendix is assessed in multiple planes. Colour Doppler and targeted views may be used to document inflammation, fluid, an appendicolith or another visible finding.
- 4
Result and escalation
The main observations and limitations are explained. A written report is provided, and urgent hospital or clinical review is recommended when findings or symptoms are concerning.
Clinical limitations
What can happen after an inconclusive scan?
Non-visualisation is not the same as a normal appendix. If the appendix cannot be seen, the report will describe secondary signs, technical limitations and the need for clinical correlation.
Depending on age, pregnancy status, symptoms and examination findings, the next step may be urgent medical review, repeat examination, blood and urine tests, observation, CT or MRI. In adults with significant right lower quadrant pain, CT is frequently used because it assesses the appendix and alternative causes more comprehensively.
When symptoms are strongly suggestive of appendicitis, clinicians may recommend hospital treatment or surgical review even when imaging is not definitive.

Patient questions
Appendicitis ultrasound FAQs
These answers provide general guidance. Suspected appendicitis needs clinical assessment, and individual medical advice takes priority.
What is an appendicitis ultrasound scan?
It is a focused ultrasound examination of the right lower abdomen. The practitioner looks for the appendix where visible and for signs that may support appendicitis, such as enlargement, non-compressibility, surrounding inflammatory change or fluid. The scan may also identify another visible cause of pain.
Can ultrasound confirm appendicitis?
Ultrasound can show findings that strongly support appendicitis when the appendix is clearly seen. However, the appendix is not always visible, and an inconclusive or normal-looking scan cannot always exclude appendicitis. Clinical review, blood tests, observation, CT or MRI may still be required.
When should I go to A&E instead of booking?
Go to A&E for severe or rapidly worsening abdominal pain, pain spreading across the abdomen, repeated vomiting, fainting, marked weakness, breathing difficulty, confusion, or signs of sepsis. Do not delay urgent assessment to attend a routine private scan.
What symptoms may lead to an appendix scan?
Symptoms may include pain beginning near the belly button and moving to the lower right abdomen, increasing pain with movement or coughing, nausea, vomiting, loss of appetite, fever, diarrhoea or constipation. These symptoms have many possible causes and require clinical assessment.
How should I prepare?
Follow the instructions in your booking confirmation. You may be asked to avoid food for several hours, and some patients may be asked to attend with a comfortably full bladder. Do not fast or delay urgent medical care when symptoms are severe or worsening.
How long does the scan take?
The focused examination commonly takes around 20 minutes, although the appointment may be longer if the appendix is difficult to visualise or surrounding structures need assessment.
Will the scan hurt?
Ultrasound itself is non-invasive and does not use radiation. The practitioner may apply graded pressure over the right lower abdomen, which can feel uncomfortable when the area is tender. Tell the practitioner if the pain becomes too strong.
Why might the appendix not be seen?
The appendix may be obscured by bowel gas, body habitus, overlying bowel, its anatomical position or discomfort limiting probe pressure. Non-visualisation is common and does not by itself rule out appendicitis.
Do I need a GP referral?
No referral is normally required for private booking. However, suspected appendicitis is an urgent clinical condition, so a GP, NHS 111 or emergency department may be more appropriate depending on your symptoms.
When will I receive the results?
The practitioner will usually explain the main observations after the examination and provide a written report. Urgent or concerning findings require prompt clinical or hospital assessment; the ultrasound report is not a substitute for medical examination and treatment.
