Radiology Exam: Ultrasound Scan

An ultrasound scan is a device that uses high-frequency sound waves to create images of the inside of the body. The scans are used to assess soft tissue structures, including muscles, blood vessels, the heart and various organs.

Technological advancements in the field of ultrasound now include images that can be made in a three-dimensional view (3-D) and/or four-dimensional (4-D) view. A 4-D is a 3-D view that also shows movement.
