What is Obstetric and neonatal diagnostic imaging?
Neurosonographers use ultrasound technology to 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 in infants diagnosed with sickle cell anemia. Like other sonographers, neurosonographers operate transducers to perform the ultrasound, but use different frequencies and beam shapes than obstetric and abdominal sonographers. \n\nObstetric and gynecologic sonographers specialize in the study of the female reproductive system. This includes one of the more well known uses of sonography: examining the fetus of a pregnant woman to track its growth and health.
