Stillwater Billings Clinic Radiology Department provides comprehensive radiology services including diagnostic x-rays, digital mammography, CT scans, and ultrasounds. Certified Radiologic Technologists perform all procedures in the imaging center. These highly skilled technologists are responsible for positioning the patient to provide a quality and accurate image. These technologists partner with Billings Clinic Radiologists to interpret the images. The results of these images are then shared with your provider.


Ultrasound utilizes sound waves to collect images of organs and tissues in the body. A transducer, utilized by the ultrasound technologist, produces high frequency sound waves that travel through the body. The sound waves send back echoes as they bounce off organs and tissues. The computer equipment utilized transmits those echoes into visual data. Ultrasound does not involve exposure to radiation.

Ultrasound services are offered on Wednesdays in the morning. A doctor’s order is necessary for the ultrasound procedure.


Our new 3-D Mammography Machine, enhanced with the smart curve paddle system, offers patients comfort, and earlier breast cancer detection compared to 2-D alone.  This state of the art equipment is both a screening and diagnostic tool for our patients right here, close to home.

Mammography services are offered by appointment every Monday, Tuesday, and Thursday.
