If you have been feeling a bit under the weather recently and are not sure what is going on, then you may need to visit a consultant. They may tell you that you need to have an ultrasound scan, but you don't really know what this involves. However, you will certainly want to get a lot more information about this technology before you go in for the test, so how does it work?

Non-Invasive Procedure

Ultrasound imaging is a very clever and non-invasive method that allows skilled technicians to have a look at the body's internal organs and structure. Using special equipment, they are able to gather information in the form of sound waves that can then be converted, using a computer program, into a two- or three-dimensional image.

High Sophistication

Doppler ultrasound equipment is even more sophisticated, and it can actually track the movement of blood or other bodily fluids. In this way, a doctor will be able to see if there are any issues with veins, arteries or other related organs.

Ultrasound imagery can be used to help determine the condition of a variety of internal organs and to show the presence of swelling or infection. Unlike the x-ray approach, it does not use any radiation, and there is no threat to the patient or to the technician during application.

During the Test

In terms of preparation, little is required. You may be asked to refrain from drinking or eating before the test, but once you arrive, you will simply need to lie down and work with the technician. They will apply a gel substance to the area in question and this helps transmit and receive the data. A small probe known as a transducer will then be placed onto the skin and will send high-frequency sound waves through the gel and into the body, which will be reflected away from the internal organs and back to the probe itself.

Extra Uses

In certain types of situations, ultrasound technologies can be used to help during a biopsy, and the information received can help to guide the surgeon to the precise area.

Getting Ready

So, this is a non-invasive and completely safe procedure that can provide a great deal of information and help your doctor to come up with their diagnosis. If you need any further information before you go ahead with the test, ask your medical care staff for their help.
