The Pediatric Radiology Department at Boston Children's Hospital combines individualized care, specialty expertise, and the most advanced technology to obtain the highest quality ultrasounds for children with images that provide the most accurate diagnoses for patients ranging in age from fetal life through young adulthood. Pediatric Ultrasound, which is also known as sonography, is a painless, non-invasive imaging technique that lets us look inside your child's body without the use of radiation. It uses high-frequency sound waves to create pictures of organs, muscles, soft tissues and blood vessels.

Hemophilia is an inherited bleeding disorder in which the blood does not clot normally because of a missing or dysfunctional clotting protein. Clotting proteins, also called clotting factors, work with other blood components such as platelets, von Willebrand factor, and other proteins to form a blood clot. When any of these components is absent or low, increased bleeding can result. If clotting factor VIII (8) or factor IX (9) are affected, this bleeding disorder is called hemophilia.
