The MRI scanner is usually shaped like a tube surrounded by a large magnet. The child lies on the scanning bed, which is then positioned into the tube. Occasionally, your child may require a liquid contrast agent to make better images, either before or during the scan. The length of the scan depends on the area of the body being evaluated. Generally, MRI takes from half an hour to an hour and a half to complete.
Some children have a fear of closed in places and loud noises.
The technician does not stay in the room with your child during the scan, however the child is monitored at all times through an observation window and an intercom system. Ultrasound An ultrasound uses high-frequency sound waves to produce images of the internal organs and structures of the body. It is a quick method for imaging without the use of radiation. Using ultrasound, sound waves are sent through the body by a tool called a transducer. A gel is applied to the surface of the skin in the area that is to be imaged, and the transducer is placed immediately over it.
