What Is An 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 An Ultrasound?
Some of the advantages of Ultrasound is it does not use x-rays, the images are real time, that can show the internal organs, as well as, movement of these organs. Blood flow can be measured as to its volume and speed. New technology includes 3 dimensional images as well as 4 dimensional techniques. Ultrasound is non-invasive and involves no radiation.
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.
Most Ultrasound exams will last approximately 20-40 minutes.
