This scan checks any lump that may be felt or visualised in the body. Ultrasound is usually the first line method of examination for anyone with a general swelling or bump.The most common causes for lumps in the body are ganglion cysts, lipomas and sebaceous cysts which are all usually easily identifiable on ultrasound.
Other common problems which can show on the scan are:
No preparation for this scan is neccesary.
Before the ultrasound scan our sonographer will explain the examination procedure. You will be asked to lie on the examination couch exposed the area of the lump. We will put a little bit of gel on your skin and a small ultrasound probe will be used to obtain images of your internal organs. During and after the examination our sonographer will explain the findings and an ultrasound report will be issued to take away with you.
Ultrasound imaging is a medical diagnostic technique where sound waves are being used to image various parts of the body.
Other terms for ultrasound imaging are: sonograms, US and sonography.
Ultrasound is widely used these days as it is painless and safe to adults, children and foetuses. There are no side effects such as the ones associated with radiation.
During the ultrasound scan, the sonographer rests a small probe over the skin. This probe produces sound waves i.e pulsations that travel through the tissues. Some of the sound waves are being reflected back to the transducer and the computer analyses the returning echoes and produces the image on the screen. It is the same principle with the sonar the navy uses.
Ultrasound is being used to image mostly solid organs such as liver, kidneys, uterus and ovaries, muscles and blood vessels and babies in the womb.
It has however limited value in organs such lungs, bone, stomach and bowel/colon.
Ultrasound images are black and white but colour Doppler is being used to evaluate organ and blood vessel blood flow and this is what the red and blue colours on the screen are.
