Ultrasound works by bouncing sound waves off the inside of the body. Echoes from the waves are converted into an image, called a sonogram. The technique is sometimes called sonography or sonar. Ultrasound has become an increasingly important part of diagnostic imaging, providing information that can guide a physician's care for a patient’s clinical management.
Ultrasound visualizes tendons, muscles, joints, vessels and internal organs. The sonographer uses a handheld probe that is passed over the body targeting certain areas. The sounds or echoes from the probe are sent to a computer housed within the ultrasound machine. These echoes are then transformed into pictures.
Ultrasounds have no long term side effects.
