What is an ultrasound?

Ultrasound imaging is based on the same principles involved in the sonar used by bats. Ultrasound imaging is one of the most widely used diagnostic procedures available. It provides a safe, noninvasive and virtually painless means of observing soft tissue anatomy.

Our ultrasound system generates an advanced level of image quality to help your physician diagnose your condition with confidence. It may provide your doctor all the information needed to recommend a course of action, eliminating the need for other types of more complicated exams or exploratory surgery.

What can you expect during an ultrasound

Before your ultrasound

You should wear comfortable, loose fitting clothing for your exam. Other preparation depends on the type of examination you are scheduled for. For some scans, your doctor may instruct you not to eat or drink for as many as 12 hours before your appointment. For others, you may be asked to drink up to six glasses of water, two hours prior to your exam, and avoid urinating so that your bladder is full when the scan begins.

During the ultrasound

The technologist will assist you onto the examination table. At this time, a transmission gel will be applied to the area of your body that will be examined. A transducer will be moved slowly over the body part being imaged. You will not feel a thing except for the slight pressure and movement of the transducer. It is important that you remain still and relaxed during your procedure.The exam takes between 30 and 60 minutes, depending upon the anatomy under study.
