Based on the principle of sonar, Diagnostic Musculoskeletal Ultrasound uses sound to determine an object’s size, shape, and consistency. This can also help determine whether it’s solid or filled with fluid. In healthcare, this can be used to detect changes in organs, tissues, and vessels as well as abnormal masses, such as tumors. During an ultrasound exam, a transducer is used to send the sound waves and record the echoing waves. When the transducer comes in contact with your skin, it sends small pulses of inaudible, high-frequency sound waves into your body. These sound waves will then bounce off of internal organs, fluids, and tissues, and the receiver within the transducer will record small changes in the pitch and direction of the sound. These waves are then measured and displayed on a computer, creating a real-time image on the monitor. Video loops of the images may also be created and saved. This procedure does not require an injection of a contrast agent and because it doesn’t use radiation, it does not pose any of the health risks commonly associated with X-rays. In addition to this, you will not be confined in an enclosed space during the ultrasound, eliminating any issues with claustrophobia.
