Ultrasound, also called sonography, is an imaging procedure that uses high-frequency sound waves to produce real time images displayed on a computer screen. Ultrasound is most commonly utilized during pregnancy to monitor the baby's development stages, and to guide physicians during certain procedures. Ultrasound is used as a key tool to diagnose a wide variety of conditions affecting the organs in the body without the use of ionizing radiation. During the test, patients will lie on the table and will experience little or no discomfort. Depending on the exam, the allotted time could range from 30 minutes to over an hour. The ultrasound procedure may require specific Exam Preparations which can be reviewed prior to your appointment.
