The Gonzaba Story



Complete Radiological Care Under One Roof

Gonzaba Medical Group (GMG) is one of the leading providers of Diagnostic Imaging Services in San Antonio with radiology services offered at four of our seven convenient locations – Main, Northwest, Woodlawn and Downtown.

Our radiology department is accredited by the American College of Radiology and Intersocietal Commission for the Accreditation of Vascular Laboratories. This means we have voluntarily gone through a rigorous review process to ensure we meet nationally-accepted standards. Through education and certification, GMG personnel are well-qualified to obtain and interpret medical images. Our equipment is appropriate for the test or treatment you receive and the facility meets or exceeds quality-assurance and safety guidelines.

GMG uses the latest diagnostic imaging technology available and offers several modalities of radiological services. GMG is staffed with a Board Certified Radiologist, experienced technicians and caring office personnel. Our success in reporting clinical images is the result of years of experience and is supported by referrals from the physician community.

There are seven radiological services that GMG provides:
  1. MRI (Magnetic Resonance Imaging) – MRI is a test that uses a powerful magnetic field, radio waves, and a computer to produce detailed pictures of the body’s internal structures that are clearer, more detailed and more likely in some instances to identify and accurately characterize disease than other imaging methods.
  2. CT (Computerized Tomography) – CT (also called “CAT” scan), is a diagnostic imaging test used to create detailed images of internal organs, bones, soft tissue, and blood vessels. The cross-sectional images generated during a CT scan can be reformatted in multiple planes, and can even generate three-dimensional images.
  3. Ultrasound – Ultrasound imaging uses a transducer or probe to generate sound waves and produce pictures of the body’s internal structures. It does not use ionizing radiation, has no known harmful effects, and provides a clear picture of soft tissues that don’t show up well on x-ray images. Ultrasound is often used to help diagnose unexplained pain, swelling, and infection.
  4. Vascular Studies – Uses Ultrasound technology to evaluate the body’s circulatory system and help identify blockages and detect blood clots. A Doppler ultrasound study – a technique that evaluates blood flow through a blood vessel – is usually part of this exam. Ultrasound does not use ionizing radiation, has no known harmful effects, and provides a clear picture of soft tissues that don’t show up well on x-ray images.
  5. Echocardiograms – Uses sound waves to produce images of your heart. This commonly used test allows your doctor to see your heart beating and pumping blood. Your doctor can use the images from an echocardiogram to identify heart disease.
  6. Bone Densitometry – Also called dual-energy x-ray absorptiometry or DEXA, uses a very small dose of ionizing radiation to produce pictures of the inside of the body (usually the lower spine and hips) to measure bone loss. It is commonly used to diagnose osteoporosis and to assess an individual risk for developing fractures. DEXA is simple, quick, and noninvasive. It’s also the most accurate method for diagnosing osteoporosis.
  7. Mammography – Is a specific type of breast imaging that uses low-dose x-rays to detect cancer early – before women experience symptoms -when it is most treatable. Mammography plays a central part in the early detection of breast cancers.

The radiology department has a dedicated appointment/question line for your convenience. Please call 210-923-XRAY (9729) to speak with an Ancillary Coordinator.


GMG’s Radiology Department also boasts industry-leading RIS/PACS (Radiology Information System/Picture Archiving and Communication System) technology. A PACS enables nearly instant access to images and patient data within radiology. Together with a RIS and other clinical information systems, images can be integrated with the radiology report and with other patient information systems, such as laboratory, pharmacy, cardiology and nursing reports.
