An ultrasound scan uses high-frequency sound waves to create images of the body’s interior, similar to pregnancy scans. A sonographer or radiologist presses a small probe against the skin, generating sound waves that bounce back to form images on a screen. The probe can be moved for different angles, helping to examine organs, blood flow, and detect blockages. For internal exams, a probe may be inserted into the vagina. The sonographer will explain the procedure and obtain your consent beforehand.
Your healthcare provider has referred you for an ultrasound scan. Ultrasound examinations can work towards aiding diagnoses and monitoring a range of medical conditions. This leaflet provides information about the scan, how to prepare, and what to expect during your appointment.
The Oxford Community Diagnostic Centre cannot see patients under the age of 16 for Ultrasound Scans.
There are no known risks associated with ultrasound scans.
Are you required to make any special preparations in advance?
Different scans may require different forms of preparation.
In the case of a pelvis, kidney, or bladder scans you may need a full bladder. Full instructions for this will be provided in your appointment letter.
For other examinations such as gallbladder and pancreas scans, fasting may be required for several hours before the scan.
This will also be detailed in your appointment letter.
What happens during the scan?
The scanning room will have dimmed lights to enhance the visibility of the images. A gel is applied to the skin over the area to be scanned to allow the probe to slide easily and produce clearer pictures.
Depending on the scan your healthcare provider has requested, you may be asked to take deep breaths and hold them briefly. For internal exams, a probe may be inserted into the vagina. The sonographer will obtain your consent beforehand.
Following the scan, you may resume your regular activities. You can eat and drink as normal.
The report will be sent to the clinician who referred you.
