Diagnostic and therapeutic services

The Diagnostic and Therapeutic Care Line facilitates the provision of timely, cost-effective, and high-quality diagnostic care in safe and secure environments.

It includes the clinical services of Medicine, Radiology, Nuclear Medicine and Radiation Oncology. These services function in the settings of ambulatory care, acute care, mental health, geriatric, and rehabilitative care. Facility based diagnostic service employees include physicians, nurses, technicians, technologists, administrators, as well as program assistants and analysts. Combining these diagnostic services and employees into an interdisciplinary group facilitates the sharing of knowledge and permits uniformity of practices and policies.


We offer a variety of imaging services to include X-ray, Ultrasound, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Interventional (special procedures) and Breast Imaging to diagnose and treat diseases within the body.

Nuclear medicine

Nuclear Medicine is a medical specialty that uses radiopharmaceuticals to image the body and treat disease. Radiopharmaceuticals are tiny amounts of radioactive materials. They can be detected by advanced instrumentation to provide information about the physiology (functioning) and the anatomy of the body.

The information gathered helps to establish a diagnosis and aids the physician in the determination of the most effective treatment. Some of Nuclear Medicine’s most frequently performed studies include:

  • Positron Emission Tomography (PET)
  • Nuclear Cardiac stress test
  • Bone Scan
  • Bone Density (BMD)
  • HIDA Scan
  • MUGA Scan
  • Gastric Emptying Scan
  • Renal Scan
  • Thyroid Uptake & Scan
  • V/Q (Lung Scan)

Patients will receive a courtesy call from a Nuclear Medicine technologist or Physician Associate a day prior to the scheduled appointment to discuss the test and go over any concerns.

Nuclear medicine location: 2C-260, 2nd floor, near green elevator, next to Radiology
PET location: 1st floor (Check in is in MRI)
Hours: 7:30 a.m.-4:00 p.m.
Appointments: Patients are referred by their physician.

Radiation therapy

The radiation oncology section works with your health care team to target cancerous tumors safely and precisely using radiation therapy.

Radiation oncologists specialize in using high-energy X-rays to kill or damage cancer cells and either destroy tumors or control their growth. Our doctors sometimes use radiation therapy in combination with surgery, chemotherapy, or other cancer treatments. The radiation therapy you receive will depend on cancer type, tumor size and location, and your general health. Our services include:

  • 3D-Conformal Radiation Therapy (3D-CRT): uses computer planning to deliver precise radiation doses that match the 3D shape of your tumor.
  • Intensity Modulated Radiation Therapy (IMRT) and Volumetric-Modulated Arc Therapy (VMAT): uses sophisticated computer planning with arcs to deliver faster and more precise radiation treatments.
  • Intracranial Stereotactic Radiosurgery (SRS): uses targeted radiation to treat a brain tumor or lesion while minimizing radiation effects on healthy brain tissue.
  • Stereotactic Body Radiation Therapy (SBRT): uses precisely focused radiation to treat tumors in your lungs, spine, liver, or other soft tissues in as little as 1-2 weeks.
  • Image-Guided Radiation Therapy (IGRT): uses detailed daily images prior to treatment, to ensure treatments are delivered accurately and precisely.
  • CT simulation performed with new GE Discovery RT scanner with the ability to minimize artifacts from metal implants.
  • Cyberknife radiosurgery: a robotic radiation delivery system with real-time tracking of tumor with submillimeter accuracy.
  • Participation in VA Cooperative Studies Program (CSP) and NCI’s National Clinical Trials Network (NCTN) cooperative group clinical trials.
  • An American College of Radiology (ACR)-Accredited Radiation Therapy Center
