Doppler ultrasound is based on the same science as conventional ultrasound, which uses sound waves to create an image of the organ. The difference between the two is that Doppler technology uses a different frequency of sound waves to help our specialists measure the speed and direction of blood flow through a blood vessel, including all of the body’s major arteries and veins.
Doppler ultrasound images help physicians to assess:
- Clots or other blockages to blood flow
- Narrowing of vessels which may be caused by plaque
- Tumors and congenital vascular malformation
With the information that the physician gathers from a Doppler ultrasound, they can determine whether or not it is appropriate for the patient to receive another procedure, such as an angioplasty.
Preparing for a Doppler Ultrasound
Preparation for your Doppler ultrasound exam is determined by the part of your body to be examined.
- Wear comfortable, loose-fitting clothing for your Doppler ultrasound exam.
- Remove all clothing and jewelry from the area of your body being examined prior to the exam as these objects interfere with the quality of the images.
- The portion of your body that is being examined will be undressed and you may be asked to wear a hospital gown to cover yourself during the exam.
Depending on what your doctor is looking for, he or she may ask you to prepare by fasting or to consuming liquids in advance of your exam. Please ask your doctor.
You may continue to take regular medications.
What to Expect During a Doppler Ultrasound Exam
Most ultrasound examinations are painless, fast and easy.
You will be positioned on an examination table lying face up. The radiologist or sonographer will apply warm water-based gel on your skin and then place the transducer, a hand-held device that sends and receives ultrasound signals firmly against your body, moving it back and forth over the area of interest until the desired images are captured. There is usually no discomfort from pressure as the transducer is pressed against the area being examined, however, you may feel pressure or minor pain if the transducer is performed over an area of tenderness.
When the Doppler ultrasound study is performed, you may actually hear pulse-like sounds that change in pitch as the blood flow is monitored and measured.
After the examination is complete, the gel will be wiped off of your skin, and you should be able to resume your normal activities immediately.
A radiologist will review your exam images and report the findings to your doctor. Your doctor will then discuss the findings and next steps with you.
