A carotid ultrasound is also performed to: locate a hematoma, a collection of clotted blood that may slow and eventually stop blood flow. detect dissection of the carotid artery, a split between layers of the artery wall that may lead to obstruction of blood flow or a weakening of the wall of ...
an aneurysm in the aorta. Additionally, ultrasound may be used to provide guidance for biopsies. Doppler ultrasound images can help the physician to see and evaluate: blockages to blood flow (such as clots). narrowing of vessels (which may be caused by plaque). tumors and congenital vascular ...
What does ultrasound show? Ultrasound creates pictures of the internal organs of the body from sound waves. There is no radiation involved. The sound waves are directed into a specific area of the body through a transducer .
