What is ultrasound?
Ultrasound scanning, often referred to as sonography, is a method that obtains images of internal body organs through the use of high frequency sound waves which are recorded and displayed as images on a monitor. Ultrasound is used to diagnose multiple body parts to identify palpable masses, fibroids, kidney stones, causes of uterine bleeding and other medical conditions.
Carotid ultrasound may show plaques that narrow the carotid artery and limit the flow of blood to the brain. Images are captured in real time and therefore show movement of internal tissue, body organs, blood flows and heart valve functions and the condition of embryo and fetus in pregnant women.
What are the advantages of ultrasound?
Ultrasound does not use x-rays, so it does not expose you to any ionizing radiation. The images are captured in real time, meaning that they can show both the internal organs and the movement of these organs. Blood flow can be measured for its volume and speed. New technology includes three- dimensional images as well as four-dimensional techniques. Like other imaging tests, ultrasound is non-invasive.
Preparation for ultrasound
The preparation for an ultrasound varies for the part to be examined. Preparation instructions will be given when the exam is scheduled.
Exam Time
Most Ultrasound exams will last approximately 20-40 minutes.
Exam Results
After your exam, the radiologist will review your images, and a report will be sent directly to your physician. Reports are available within 24 to 72 hours.
