Sonography
Sonography uses an ultrasound scan to capture live images inside a patient’s body. This will allow your doctor to determine any issues with organs, vessels or tissue without making an incision.
Ultrasound scans are typically associated with pregnancy because it uses no radiation, unlike other imaging techniques. However, sonography can also be used for other reasons.
Your doctor may choose to perform an ultrasound scan if you have pain, swelling or other symptoms that require them to need an internal view of your organs.
An ultrasound can provide a view of the following areas:
- Bladder
- Brain, especially for infants
- Eyes
- Gallbladder
- Kidneys
- Liver
- Ovaries
- Pancreas
- Spleen
- Thyroid
- Testicles
- Uterus
How to prepare for an ultrasound
In most cases, ultrasound scans are done on the spot, but they can be scheduled too. For a scheduled ultrasound scan, there are several ways you can prepare for an ultrasound scan. Preparation varies depending on the organ that your doctor wants to examine.
If your abdomen is being examined, you may need to fast between eight to 12 hours before. Undigested food will make it difficult for your doctor to get a clear view.
For the gallbladder, liver, pancreas, or spleen, you may need to stay away from fatty foods the night before your test and fast until your procedure. You may still drink water and take any necessary medications if instructed by your doctor.
For your bladder, you may need to drink a lot of water beforehand so that your bladder is complete and can be visualised better.
Ask your doctor any questions and follow their instructions before getting an ultrasound scan.
