This is a medical imaging method that uses high frequency sound waves to obtain diagnostic images of structures within the body. Ultrasound can be used to view an unborn foetus, examine internal organs, show movement of internal tissues and organs, to guide procedures such as needle biopsies, image the breast and guide biopsies of breast cancer and evaluate structures such as the thyroid and scrotum.
How Do I Prepare for the Ultrasound Exam?
You will be expected to wear comfortable clothing. For specific examinations, you will be requested not to eat or drink for up to 8hr before the examination. If you are getting a pelvic ultrasound scan done, you may also be asked to drink up to 6 glasses of water 2 hours prior to the exam and avoid passing urine to allow your bladder to be full when the exam begins.
What to Expect During the Ultrasound Examination
The examination is painless and takes less than 30 minutes. After being positioned on the examination table, a clear gel will be applied by the sonographer to the area being examined. The sonographer firmly presses the transducer over the area being examined to capture the image. After completion of the procedure, you should be able to resume your normal activities.
