VA North Texas Health Care System
Nuclear Medicine Service
Nuclear Medicine provides a full range of advanced accredited functional imaging and therapy services for the Veterans Affairs North Texas Health Care System, including General Nuclear Medicine, Nuclear Cardiology, Nuclear Medicine Therapy, Positron Emission Tomography (PET), Single Photon Emission Computed Tomography (SPECT) and bone densitometry (DXA).
What is Nuclear Medicine?
Nuclear Medicine is a medical specialty that uses radiotracers (radioactive drugs) to diagnose, treat, and evaluate the response to treatment for many health conditions. These radiotracers may be administered through different routes, but are most commonly given intravenously (within a vein), inhaled, or swallowed to investigate the function of various organs or body systems. Specialized scanners are used to produce the images needed to make a medical diagnosis.

- How do I prepare for my exam?
Instructions vary for each Nuclear Medicine Scan or Procedure, and will be provided to you during pre-registration. It is important to notify the Nuclear Medicine Technologist or Provider of any allergies, recent illnesses, and medications you are currently taking. Also, notify staff if you are, or there is the possibility that you may be, pregnant or if you are currently breast-feeding.
How will I get my results?
Results are typically available to your doctor within two business days of procedure completion. Inpatient or stat (immediate) results are communicated in less than 60 minutes.
