Computed Tomography

Computed tomography:

  • Uses ionizing radiation similar to an X-ray
  • Obtains cross-sectional images through area of concern in a single breath hold
  • Images can be manipulated as needed to show area of interest
  • Exams may be ordered with or without intravenous contrast and can be ordered to cover the area of the body in question as needed
    • Iodine is used as a contrast agent
      • Any allergies to iodine should be brought to the attention of your physician before showing up for your appointment
      • Pre-medication regiments are available and are prescribed by your physician as needed
  • In some cases oral contrast may be ordered by your physician for your exam
  • Exams are typically completed in 5 to 15 minutes once in the CT suite, so please do not leave the radiology waiting area after you have checked in for your procedure
  • A CT scan is not a full-body tube like an MRI, and in most cases you will be able to see outside of the machine during your exam
  • Exams are conducted by registered CT technologists certified by the American Registry of Radiologic Technologists for advanced specialization training

We are radiation dose conscientious with all we do. In our CT department, we strive to achieve the lowest radiation dose necessary to provide a diagnostically acceptable CT scan for our radiologists.

  • Our CT protocols are optimized using the recommended radiation exposure guidelines set by the American College of Radiology (ACR). We operate using the lowest acceptable radiation doses in these guidelines, in order to minimize radiation exposure to our patients while still providing a diagnostically acceptable study for our radiologists.
  • Our CT department uses the latest in automatic dose modulation. This technology automatically selects the parameters of the scan to generate the lowest radiation dose possible based on each individual body type.
  • Our department also conducts random daily quality assurance and radiation dose audits, which are then submitted and reviewed by the Good Samaritan Medical Center Radiation Safety Committee to ensure that we are operating safely within the recommended guidelines set by the ACR.
  • Finally, each of our two CT machines undergo routine quality control and calibration checks to ensure they are operating as they were intended to by the manufacturer. Additionally, they are certified on an annual basis by the State of Colorado via a certified radiation physicist to ensure that they are both compliant on a state level with the accepted radiation exposure limits.

We look forward to serving your complete computed tomography needs while remaining consistent with the ALARA (As Low As Reasonably Achievable) principle of radiation safety.
