Ultrasound imaging uses sound waves to produce pictures of muscles, tendons, ligaments, nerves and joints throughout the body. It is used to help diagnose sprains, strains, tears, trapped nerves, arthritis and other musculoskeletal conditions. Ultrasound is safe, non-invasive, and does not use ionising radiation. Ultrasound imaging can show the structure and movement of the body's internal organs, and can also show blood flowing through blood vessels.

Ultrasound imaging uses sound waves to produce pictures of muscles, tendons, ligaments, nerves and joints throughout the body
Ultrasound imaging uses a small probe called a transducer and gel placed directly on the skin. High-frequency sound waves travel from the probe through the gel into the body. The probe collects the sounds that bounce back, and a computer uses those sound waves to create an image. Ultrasound captures images in real-time, so it can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels.
The images produced by ultrasound can provide a detailed view of muscles and other soft tissues. The boundaries of the muscle are clearly visible because the epimysium surrounding the muscle is a highly reflective structure. Normal muscles are relatively black, but different muscles have specific appearances on ultrasound because of the variability in the proportion of fibrous tissue and the orientation of muscle fibres. For example, the anterior tibial muscle has a generally whiter appearance than the rectus femoris.
Ultrasound imaging can also be used to analyse the extent and type of involvement of individual muscles. This can be useful in the diagnosis and treatment of medical conditions.

Ultrasound is safe, non-invasive, and does not use ionising radiation
Ultrasound is a safe, non-invasive procedure that uses high-frequency sound waves to produce pictures of muscles, tendons, ligaments, nerves and joints throughout the body. It is used to help diagnose sprains, strains, tears, trapped nerves, arthritis and other musculoskeletal conditions. Ultrasound does not use ionising radiation, unlike X-rays, but it is still capable of producing some biological effects in the body under specific settings and conditions. For example, ultrasound waves can heat the tissues slightly and, in some cases, produce small pockets of gas in body fluids or tissues (a process known as cavitation). The long-term consequences of these effects are still unknown.
Ultrasound imaging has been used for over 20 years and has an excellent safety record. It is considered safe when used prudently by appropriately trained healthcare providers. The FDA, as well as many professional societies, discourage the casual use of ultrasound and recommend that it be used only when there is a true medical need.
Ultrasound is a non-ionising form of radiation, meaning that individual photons do not have enough energy to ionise atoms. This is in contrast to X-rays, which do expose people to ionising radiation.
Ultrasound imaging uses a small probe called a transducer and gel placed directly on the skin. The high-frequency sound waves travel from the probe through the gel into the body, and the probe collects the sounds that bounce back. A computer then uses those sound waves to create an image. Because ultrasound captures images in real-time, it can show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels.
Ultrasound is a valuable tool for examining the musculoskeletal system, as it can provide clear pictures of muscles and the surrounding tissues. The boundaries of the muscle are clearly visible because the epimysium surrounding the muscle is a highly reflective structure. Normal muscles are relatively black, but different muscles have specific appearances on ultrasound because of the variability in the proportion of fibrous tissue and the orientation of muscle fibres. For example, the anterior tibial muscle has generally a whiter appearance than the rectus femoris.

Ultrasound imaging uses sound waves to produce pictures of muscles, tendons, ligaments, nerves and joints throughout the body. It can be used to diagnose sprains, strains, tears, trapped nerves, arthritis and other musculoskeletal conditions. Ultrasound is safe, non-invasive, and does not use ionising radiation. It requires little to no special preparation, although you may be asked to leave jewellery at home and wear loose, comfortable clothing or a gown.
Ultrasound imaging of the musculoskeletal system provides pictures of muscles, tendons, ligaments, joints, nerves and soft tissues throughout the body. It can show the structure and movement of the body's internal organs and blood flowing through blood vessels.
Ultrasound images of muscles show the boundaries of the muscle clearly because the epimysium surrounding the muscle is a highly reflective structure. Normal muscles are relatively black, but different muscles have specific appearances on ultrasound because of the variability in the proportion of fibrous tissue and the orientation of muscle fibres. For example, the anterior tibial muscle has generally a whiter appearance than the rectus femoris. Muscle echogenicity increases with age, which is caused by age-related replacement of muscle fibres by fat and fibrous tissue.
Ultrasound can also show greater morphologic detail in skeletal muscle than other tissues, allowing for an analysis of the extent and type of involvement of individual muscles.

Ultrasound can show the structure and movement of the body's internal organs
Ultrasound uses sound waves to produce pictures of muscles, tendons, ligaments, nerves and joints throughout the body. It can also show the structure and movement of the body's internal organs, as well as blood flowing through blood vessels. Ultrasound is safe, non-invasive, and does not use ionising radiation. It can be used to diagnose sprains, strains, tears, trapped nerves, arthritis and other musculoskeletal conditions.
Ultrasound imaging of muscles can show the extent and type of involvement of individual muscles. It can also show the boundaries of the muscle, as well as the bone echo beneath it. The appearance of muscles on ultrasound varies depending on the proportion of fibrous tissue and the orientation of muscle fibres. For example, the anterior tibial muscle has a whiter appearance than the rectus femoris. Muscle echogenicity increases with age, as muscle fibres are replaced by fat and fibrous tissue.
