An ultrasound exam is a painless and non-invasive diagnostic procedure that uses high-frequency sound waves to produce an image of the internal structures of the body. The image is displayed in two dimensions. Because an ultrasound does not use x-rays, there is no radiation exposure, which makes ultrasound completely safe, even for pregnant women. Also, ultrasound studies are quicker and less expensive than some other imaging modalities.
The quality of results from ultrasound is very much dependent on the skill of the operator. For this reason, Torrance Memorial Medical Center employs technologists and radiologists with extensive ultrasound training to perform these exams.
How do I prepare for the exam?
No preparation is necessary for the following types of ultrasound studies:
- Fetal (after fourteen weeks)
- Renal (Kidneys)
- Scrotal (Testicular)
- Thyroid (Neck)
You may eat and drink as usual before the exam and you may take your usual at-home medications as prescribed.
