Our Approach

We believe in efficient and affordable health care. A key element of that ideal comes from fast and accurate diagnostics. Our diagnostics staff is comprised of highly trained professionals eager to identify your specific needs. Once a diagnosis has been made, the journey to recovery continues with your physician as your guide. 

Our Medical Imaging is conveniently located off I-35 on Wonder World Drive.

We provide comprehensive diagnostic services to include the following:

  • Radiography (Plain-film, Myelograms, Fluoroscopy, Arthrograms, Barium studies)
  • Cat Scan (CT)
  • Magnetic Resonance Imaging (MRI)
  • Ultrasound, Interventional
  • Ultrasound
  • Bone Densitometry
  • Mammography
  • Nuclear Medicine
  • PET (Positron Emission Tomography)

All of our imaging areas are digital, meaning we’re “green.”  We’ve eliminated film and chemicals from our department. However, we have the ability to digitally print film if your referring physician requests it. A digital department allows us to be very efficient by providing our physicians the ability to access images from a secure portal on the Web so that they can review each study and the results online, or with the patient in the office. Our radiologists  interpret procedures using voice recognition. As soon as they have dictated your study, it will be available for your physician to review. This provides optimum results reporting so that your physician can be informed of your test results quickly.

Our radiologists include Dr. Douglas Smith, Dr. Stephen Swearingen, and Dr. Gregory de la Iglesia. All are certified by the American Board of Radiology and are members of the American College of Radiology, Texas Medical Association and Tri-County Medical Society.    

We provide direct scheduling at 512-753-3661. We can also provide financial counseling and, in many cases, offers individual payment arrangements.
