Sonographer doing an<unk> rdiogram of a child<unk> rdiogram in the parasternal long-axis view, showing a measurement of the heart's left ventricle Health societies recommend the use of<unk>  for initial diagnosis when a change in the patient's clinical status occurs and when new data from an<unk> rdiogram would result in the physician changing the patient's care. Health societies do not recommend routine testing when the patient has no change in clinical status or when a physician is unlikely to change care for the patient based on the results of testing. A common example of overuse of<unk>  when not indicated is the use of routine testing in response to a patient diagnosis of mild valvular heart disease. In this case, patients are often asymptomatic for years before the onset of deterioration and the results of the<unk> rdiogram would not result in a change in care without other change in clinical status.<unk>  now has a vast role in pediatrics, diagnosing patients with valvular heart disease and other congenital abnormalities. An emerging branch is fetal<unk> , which involves<unk>  of an unborn fetus.
