Ultrasound imaging (USG) is a safe, non-invasive test that uses sound waves to produce images of the structures and organs inside the upper abdomen. It is used to check any abnormalities or distension in the kidneys, gall bladder, upper aorta, liver and spleen. It does not use any radiation, and is therefore safe for pregnant women.
It is advisable to wear loose clothing before going for the test. You may be required to remove your clothing for the scan to take place. You’ll also be required to fast for at least eight hours before the test.
An ultrasound is useful to diagnose or detect the following:
An enlarged liver or spleen.
Blockage of the kidney or cancer.
Pregnancy and development of the foetus.
You will be required to lie down, before which you are to open any jewellery or metallic objects and keep it away. You will be required to expose your abdomen and the technician will apply a special lubricating gel on the area to be scanned. The technician will then put a microphone-like object on your abdomen and move it along the gelled areas so as to produce the image on a computer screen attached to it.
Let the technician know immediately if you experience sustained pain or discomfort. The process takes a maximum of 30 minutes. After it is done, you will be required to wipe off the gel and then dress up again.
