Sonography/Ultrasound

Sonography, or ultrasound, is a diagnostic study that uses sound waves to create images of various body structures. It is commonly used to examine the internal soft tissue organs, blood vessels and, since there is no radiation used, it can be used to monitor the progress of pregnancy.   Doppler Ultrasound can also be used to assess blood flow, and detect narrow arteries or clots in veins.  In some cases, special 3D imaging may also be utilized to aid in your diagnosis. 
 

Prior to your exam, you will be asked to change into a gown. The technologist will begin by asking you a series of questions regarding your medical history. These questions may include:

• Do you have any pre-existing conditions?
• What symptoms have you experienced recently?
• History of any type of surgery?

Please feel free to ask any questions you may have.

You will lie on the exam table with the area to be scanned exposed. A non-greasy gel will be applied to your skin. The technologist will use a transducer (probe), moving it across the area to be examined while applying mild pressure. You may be asked to take a deep breath, hold your breath, or roll onto your side.

Some Pelvic Sonograms require transvaginal examination, to get close up images. You can empty your bladder before this test. You will lie on your back with your knees bent. You will be asked to insert a slender shielded probe covered with non-greasy gel into the vagina, just as you would a tampon. Any movement of the probe should not be painful.

During Vascular Ultrasound exams, you may hear a "whooshing" noise. This is the sound of your blood flowing. For Arterial studies of the lower extremities, cuffs will be applied at intervals on you legs and arm to measure pressures, similar to having your blood pressure taken.
