What Is Considered a Fever? Causes & Treatment

Imaging studies

  • Chest X-ray: Chest radiograph may be needed in cases suspected of having pneumonia.
  • Ultrasonography: Ultrasonography may be needed to visualize the kidney, the liver and the gall bladder. It is important to see the kidney in cases of urinary tract infection since there is likely to be an obstruction as well.
  • CT: CT scan is usually not routine except in cases of abscesses or bone infections.
  • Echocardiography: Echocardiography is needed in cases of bacterial endocarditis.
