Comprehensive imaging services

Imaging services allow for the visualization and treatment of medical conditions. Different exams allow radiologists and physicians to view structures and activity within the body with greater clarity and with minimal invasion to the body. Imaging exams are vital for diagnosis and there are a variety of tests that can be performed.

At St. David's hospital, we offer a wide range of diagnostic imaging and radiology services that provide precise information for our team to give you the best medical treatment. Our specialized imaging services are available at 6 different facilities in the greater Austin area. For your convenience, we offer imaging services 24 hours a day, seven days a week. In order to provide you with personalized treatment, we use the latest, cutting edge diagnostic imaging technology and techniques to examine and diagnose medical conditions.

Licensed and certified imaging staff

To ensure you receive the best possible care during your exam, all of our technicians are registered by the American Registry of Radiologic Technicians and licensed through the Medical Radiologic Technology program. Additionally, all St. David's radiologists are board-certified by the American College of Radiology.

Our radiologists, technologists, registered nurses and support staff are willing and ready to work with you in any capacity—whether it is in an inpatient facility, outpatient facility, operating room or an emergency room. We strive to make you comfortable while you receive great care in a professional, friendly environment.

Medical imaging at our hospitals

Imaging services are commonly used to help doctors diagnose issues of the brain, heart and bones and assist with prenatal care and breast health. We offer a variety of imaging services, including:

  • Angiography
  • Bone density testing
  • Computed tomography (CT) scans
  • Digital and 3D mammography
  • Image-guided biopsies
  • Interventional radiology
  • Lung biopsies
  • Magnetic resonance cholangiopancreatography (MRCP)
  • Magnetic resonance imaging (MRI) scans—including 3T and cardiac MRIs
  • Mammography—including 3D mammograms
  • Pulmonary function tests (PFTs)
  • Nuclear medicine
  • Ultrasounds, including maternal fetal ultrasounds
  • X-rays

In addition to medical imaging, our facilities offer a wide range of diagnostic and laboratory tests, including dual-energy X-ray absorptiometry (DEXA) bone scans.

CT services

We offer advanced procedures using CT scans, including CT angiography (CTA) and CT enterography (CTE). CTA is a heart imaging test performed to identify blocked arteries. This technology can detect calcified plaque in the arteries and help a patient understand their risk of heart disease or failure.

Similarly, a CTE also uses this technology. However, it combines CT imaging and a contrast material (a material swallowed or injected to help distinguish among organs, tissues, bones and blood vessels) to generate images of the small intestines. The scans can help inform a diagnosis or determine the effectiveness of a treatment.

Endoscopy services

Endoscopic imaging is an advanced technology most often used to evaluate digestive health. During an endoscopy, your doctor will use a long, thin tube with an attached camera to examine inside your body. This technology allows your medical team to view tissue or the interior of an organ in great detail. Endoscopes can be used to diagnose symptoms, such as internal bleeding and inflammation, and to guide surgeries.

Low-dose computed tomography (LDCT)

Sarah Cannon Cancer Institute at St. David's North Austin Medical Center, St. David's South Austin Medical Center and St. David's Round Rock Medical Center are utilizing innovative technologies to detect suspicious lung nodules by analyzing CT exams for the presence of incidental lung nodules which could represent a malignancy. Our lung nodule coordinator works collaboratively with you, your patient and our pulmonary medicine team to improve access to care with early intervention.

What you need to know

Sarah Cannon Cancer Institute at St. David's North Austin Medical Center, St. David's South Austin Medical Center and St. David's Round Rock Medical Center provide seamless lung nodule coordination that includes:

  • Continuity of care and ongoing treatment by a lung nodule coordinator
  • Personalized lung cancer risk evaluation and clinical assessment
  • Individualized care and treatment recommendations from our radiology and pulmonary team
  • Detailed discussion of the benefits and risks of clinically appropriate evaluation

Ultrasound services

Ultrasounds use high-frequency sound waves used to produce images of body structures. This imaging technique is offered at all St. David’s HealthCare hospitals. This technology is commonly used in maternal-fetal medicine and several other medical specialties, including abdominal, thyroid and women's health scans.
