An ultrasound examination is an imaging technique that uses sound waves to view soft-tissue organs within the body. An ultrasound uses high frequency sound waves to visualize organs within the body. High frequency sound waves (not audible to the human ear) are sent into the body, reflected back to the ultrasound camera to produce an image composed of various shades of grey.

Our expert staff specialists, employing ultrasound equipment and techniques, ensure that we provide you with the best diagnostic assessment to support you and your doctor.

There are no known side effects from ultrasound and this is why it is an excellent tool to image the fetus. Ultrasound has many applications, it can be used for general body imaging, obstetrical and gynecological exams, small part, pediatric, musculoskeletal examinations, interrogation of vasculature  and it aids in biopsy procedures
