Computed Tomography (CT Scans)

Computed tomography (CT scans) are often used in conjunction with other forms of medical imaging include radiography, ultrasound and MRI. In the trauma setting, it is the study of choice to evaluate patients with either major or minor trauma. With a single scan, multiple organ systems and skeletal structures can be evaluated quickly and safely. CT scans can be used to evaluate almost every portion of the body in seconds. We continue to actively improve our CT scanning capabilities with both hardware and software improvements.

CT of the body is routinely used to evaluate:

  • Staging of Malignancy
  • Evaluation of function – Heart, kidneys, liver, and even the lung with specialized images
  • Fever or pain of unknown origin
  • Trauma
  • Vascular evaluation both in the trauma setting and in presurgical planning for chronic process.
  • Evaluation of the Chest in critically ill patients when there are many co-existing processes present. This may help guide more specific target therapies.

We actively review all CT protocols to ensure patient safety. Our radiation safety committee reviews and evaluates all our CT protocols with phantoms and other devices to ensure they ensure the lowest possible radiation dose. Radiation physicists are actively involved in this process. The scanners are routinely checked and calibrated for accuracy.
