What is Ultrasound?
Ultrasound imaging (or sonography) is a method of acquiring information about the inside of the body using high frequency sound waves. Because ultrasound examinations are captured in real-time, they can show the size, shape and texture of the internal organs and blood vessels. Ultrasound waves cannot pass through gas so the stomach or bowel cannot be evaluated.
Is it safe?
For standard diagnostic ultrasound examinations there are no known harmful effects. No ionising radiation is involved.
Preparation for the scan
For some ultrasound scans, patient preparation may be required. Detailed instructions are given at the time of booking your appointment. For certain scans, you may be required to fast , whilst for others, you will be asked to drink several glasses of water and to fill your bladder prior to examination. Please check with the centre if you are unsure as to which preparation is required for your scan.
What happens during the scan ?
During the procedure, you will be asked to lie, usually face up, on an examination table. A gel is applied to the skin, and an ultrasound probe (transducer) is moved over the gel to acquire the images.
How long will the scan take ?
The examination takes approximately 20 minutes
When do I get the results?
The radiologist (specialist imaging consultant) will write a report to your referring doctor detailing the findings from the scan. The report will be sent to your referring doctor usually within 48 hours.
