An ultrasound examination is an imaging technique in which deep structures of the body can be visualised by recording echoes of ultrasonic waves which are directed into the tissues. Unlike x-rays which are potentially dangerous, ultrasound waves are considered to be entirely safe.
With the heart, we can use it to watch how it beats, look at its size and see if there is an enlargement. With the intestines, we can assess if muscles are contracting properly as part of the body’s mechanisms for processing food. It is ideal for getting a close look at small organs (kidneys, liver and spleen) and to check for foreign structures in the chest. Images can be frozen and then printed from the computer to provide a positive record of the examination.
