Ultrasound uses high-frequency sound waves to produce moving images of soft tissues of the body. It produces images of exceptionally high quality and allows physicians to visualize small differences in tissue, which is especially useful in the diagnosis of disease conditions. Ultrasound is painless and non-invasive is considered one of the safest diagnostic tools available.
Ultrasound provides excellent images of:
- A fetus
- Blood vessels
- Many other parts of the body
What is an Ultrasound like?
An ultrasound takes place in a dimly lit spacious private exam room. You will be asked to lie down on a cushioned exam table. You will have warm gel placed on the area to be scanned. A wand will be moved across the area and images will be obtained. You may be asked to hold your breath for a few seconds. Depending on the exam, it will usually take 20 minutes to one hour.
How does an Ultrasound work?
The wand emits high frequency sound and receives the returning echoes. These echoes are analyzed by the ultrasound machine and produce moving, real-time images. Still and moving images are taken to perform the study.
How to prepare for an Ultrasound
Preparation will depend on the type of exam you are having. For some exams you will need to fast for 8-10 hours, for others you will need a full bladder, others require no preparation at all. Your provider will give you your preparation instructions. If you need to change into a gown, it will all be done in the same room as your exam.
