An ultrasound scan deploys high-frequency sound waves to produce live images of the human organs. Also known as a sonogram, it involves no radiation and allows the doctor to locate the abnormalities of the human organs, blood vessels, bones and soft tissues. The ultrasound scan is a preferred method of scanning for pregnant ladies and other abdominal diseases. Most of the times, an ultrasound scan, is recommended to detect diseases and abnormalities of the following organs:
- Uterus; and
- Blood Vessels
To prepare for an ultrasound scan, you are typically asked for fast for the preceding 8 to 12 hours. This fasting is to ensure that the undigested food does not obstruct the sound waves and distort the picture. Additional precautions or instructions may be given based on the part of the body required to be scanned.
