Ultrasound, or sonography, uses high-frequency sound waves to produce images of the body without the need for ionizing radiation.

Because of their safety and efficacy, doctors order ultrasound tests frequently. Ultrasound exams at DIOS are read by a board-certified radiologist, a physician specially trained to interpret ultrasound studies.

The nature of ultrasound also lends to its common use in women's imaging, whether examining a developing pregnancy, the breast, or the pelvis.  The real-time nature of ultrasound also allows for effective needle guidance in injection, aspiration, and biopsy procedures.

The State of Oregon implemented a law in 2015 that requires a health care provider's order for any medical imaging.  Due to this, we cannot offer 3D/4D OB ultrasounds as a complimentary service along with OB anatomy survey exams.
