Abstract：
:Ultrasound has proved to be a valuable diagnostic tool in the practice of obstetrics. Its rapidly increasing use by the office-based obstetrician, however, has opened a potential new area of legal vulnerability. The malpractice liability that may arise from its use is reviewed and practical ways to avoid it are considered.
