Sonography, or ultrasonography, is the use of sound waves to generate an image for the assessment and diagnosis of various medical conditions. Diagnostic medical sonographers may specialize in obstetric and gynecologic sonography, abdominal sonography, neurosonography, breast sonography, vascular sonography and cardiac sonography.
Obstetric and gynecologic sonographers specialize in the imaging of the female reproductive system. One of the well-known uses of sonography: examining the fetus of a pregnant woman to track the baby’s growth and health.
Abdominal sonographers inspect a patient’s abdominal cavity to help diagnose and treat conditions primarily involving the gallbladder, bile ducts, kidneys, liver, pancreas, spleen, and male reproductive system.
Neurosonographers focus on the nervous system, including the brain. In neonatal care, neurosonographers study and diagnose neurological and nervous system disorders in premature infants. They also may scan blood vessels to check for abnormalities indicating a stroke.
Breast sonographers use sonography to study diseases of the breasts. Sonography aids mammography in the detection of breast cancer. Breast sonography can also track tumors, blood supply conditions, and assist in the accurate biopsy of breast tissue. Breast sonographers use high-frequency transducers, made exclusively to study breast tissue.
