Low-Dose Computed Tomography (CT)

We do not just meet the standards in low-dose radiation. We set them.

CT, also called CAT scan or Computed Tomography, is a type of diagnostic test that uses sophisticated, computerized X-ray equipment to produce cross-sectional images that enable detailed evaluation of anatomy to help detect a variety of diseases and conditions.

Weighing the benefits of advanced imaging such as Computed Tomography (CT) with the potential risk of exposing yourself to radiation is always a careful balance. At Fairfax Radiology, your health and well-being and that of your loved ones are our top priorities. That is why we were one of the first Radiology practices in the nation to provide low-dose CT scanning at all of our facilities. It is why we have built an extensive patient safety program that ensures every scanner is carefully programmed and tested to provide the lowest achievable radiation dose.

As part of our ongoing commitment to quality and safety, Fairfax Radiology has achieved accreditation status through the American College of Radiology (ACR), for various imaging modalities that we offer. For CT, the ACR Accreditation Program evaluates the qualifications of personnel, appropriateness of different technical scan parameters and ensures that optimal minimal radiation dose protocols are incorporated and followed. Fairfax Radiology employs the most qualified physicians, technologists and other personnel, who all require ongoing continuing education to remain skilled in providing radiology services.

With higher resolution scans and lower radiation exposure, Fairfax Radiology is the clear choice for advanced CT imaging.

Fairfax Radiology's CT Radiation Dose Reduction Initiative includes:

  • Advanced, low-dose GE CT scanners at each of our CT imaging centers.
  • Software technology, Adaptive Statistical Iterative Reconstruction (ASIR) that reduces radiation dosage.
  • CT scanners that incorporate dose notifications and alerts as well as adjust the amount of radiation based on size, shape and body composition.
  • Highly trained Technologists who adhere to specific exam protocols that maximize image quality while minimizing radiation dose.
