A Doppler ultrasound test uses reflected sound waves to evaluate blood as it flows through a blood vessel. It helps doctors evaluate blood flow through the major arteries and veins
It may be used to detect blood flow in carotid arteries and veins, also for ophthalmic artery and vein. This test helps to diagnose defective blood flow in the eye that affects the optic nerve or retinal functions.
During Doppler ultrasound, a handheld instrument (transducer) is passed lightly over the eye globe. The transducer sends and receives sound waves that are amplified through a microphone. The sound waves bounce off solid objects, including blood cells. The movement of blood cells causes a change in pitch of the reflected sound waves (called the Doppler effect). If there is no blood flow, the pitch does not change. Information from the reflected sound waves can be processed by a computer to provide graphs or pictures that represent the flow of blood through the blood vessels. These graphs or pictures can be saved for future review or evaluation.
Information about our patients is collected in a variety of ways and for a variety of reasons (e.g. Providing care and treatment, managing and planning the center, training and educating staff, research etc.). It is stored on paper and on computerized systems.
