What is ultrasound?
Ultrasound, also referred to as sonography, is a safe and non-invasive imaging modality that employs high-frequency sound waves to generate real-time, detailed images of the body’s internal structures. It plays a vital role in diagnosing, monitoring, and guiding the management of a wide range of medical conditions.
- It is safe, non-invasive, and does not expose patients to radiation.
- It assists in diagnosing medical conditions and provides a painless and patient-friendly imaging experience for accurate clinical evaluation.
- It examines organs, tissues, and blood flow with precision.
- It utilises high-frequency sound waves to produce real-time images of internal body structures.
Preparation before attending the scheduled Ultrasound appointment:
Abdominal examination:
It is best if 4 hours of fasting is observed which will enable us to carry out the detailed study of the gallbladder.
Pelvis and Urinary Tract examination:
It is advisable to drink 500 ml water 1 hour before your scan to carry out the detailed study of the urinary bladder and pelvic organs. Please do not empty your bladder before your scan.
Groin/Soft Tissues/DVT/Testes/Prostate/ AAA screening:
No prior preparation is required.
If you normally take any medications, please continue to take it and follow any specific instructions provided by your healthcare professionals.
What happens during the ultrasound examination ?
You will be asked to lie on the examination table, and the operator/assistant will help position you appropriately. Ultrasound Gel will be applied to the area being examined to enhance image quality.
Feel free to communicate with the healthcare professional throughout the procedure if you experience any discomfort or have concerns.
It’s important to remain as still as possible to ensure clear ultrasound images are captured.
You may be asked to take a deep breath, hold it for a few seconds, and then exhale. This breathing exercise can help improve image quality during the scan. However, if you are unable to do this, it’s not a problem, as it is not essential for obtaining accurate results.
What happens after the ultrasound examination ?
Your ultrasound results will be reviewed by healthcare professionals, and a report will be provided to you while you wait in the designated area.
The findings will be discussed with you, and if necessary, guidance will be offered regarding whether a follow-up appointment with your GP is needed to review the results and determine the next steps.
Please note that specific instructions may vary based on your individual circumstances. Always adhere to the advice given by your GP.
Who will perform the ultrasound examination ?
The ultrasound examination will be performed and interpreted by a skilled, expert, experienced and qualified sonographer. Results will be provided immediately.
What will my ultrasound report contain ?
A review of the ultrasound findings will contain the following key elements:
- The specific anatomical region examined will be identified and assessed for the presence of pathological or normal findings.
- Detailed description of pathological findings: In cases where deviations from normal anatomy are observed, a comprehensive description of these findings will be documented.
- Precise measurements of any identified masses, fluid collections (e.g., cysts), or other pertinent anatomical structures will be recorded.
- The echogenicity and texture of the tissues visualised will be described, including distinctions such as solid, cystic (fluid-filled), hypoechoic (relatively decreased echogenicity), and hyperechoic (relatively increased echogenicity).
- Clinical impression: A concise summary of the findings and potential diagnostic/ considerations will be presented.
- Recommendations for further management: Recommendations/ suggestions regarding subsequent diagnostic procedures, therapeutic interventions, or additional clinical evaluations will be discussed.
How long does an ultrasound examination take?
Ultrasound exams usually take between 10 and 30 minutes.
Ultrasound examination and its limitations:
Sometimes image quality can be affected by:
- Patient body habitus (obesity, excessive gas)
- Bone or air interference (making it difficult to image structures behind them)
- May not be optimal for all conditions: Other imaging techniques like CT or MRI may be needed for further characterisations.
- Patient cooperation: For certain exams, patients may need to hold their breath or maintain specific positions.
Any risk factors?
Ultrasound is generally considered a safe procedure with a low-risk diagnostic imaging technique.
It does not use ionising radiation, eliminating radiation exposure concerns.
There are no known established long-term harmful effects associated with standard diagnostic ultrasound.
Allergic reactions to the ultrasound gel are infrequent. We use water-based ultrasound gel for examinations. If you have any allergies to such products, please inform us beforehand.
The procedure is typically painless, although some pressure may be applied during the scan.
