Low-radiation computed tomographic (CT) scans effectively image orbital trauma, revealing soft-tissue injuries and muscle adhesions. This technique provides diagnostic image quality, aiding in the assessment of conditions like symptomatic diplopia.

Area of Science:

  • Radiology
  • Ophthalmology
  • Medical Imaging

Background:

  • Orbital trauma requires accurate imaging for diagnosis and treatment planning.
  • Conventional computed tomographic (CT) techniques may involve significant radiation exposure.
  • Assessing soft-tissue abnormalities in the orbit is crucial for understanding patient symptoms.

Purpose of the Study:

  • To evaluate the efficacy of a low-radiation-dose CT technique for imaging orbital trauma.
  • To assess the diagnostic image quality and demonstration of soft-tissue abnormalities using this technique.
  • To examine the contribution of soft-tissue injuries to symptomatic diplopia in patients with orbital trauma.

Main Methods:

  • Review of 75 CT examinations from 66 patients with orbital trauma.

  • Utilization of a low-radiation-dose CT technique (120 kVp, 80 mAs) in dynamic scan mode.
  • Analysis of image quality and demonstration of orbital soft-tissue abnormalities, including multiplanar reconstructions.

    • Main Results:

    • Low-radiation-dose CT provided diagnostic image quality in all cases, with excellent quality in 73 examinations.
    • Soft-tissue abnormalities, such as muscle adhesions, were well visualized.
    • The technique facilitated the assessment of injuries contributing to symptomatic diplopia.

    Conclusions:

    • Low-radiation-dose CT is a valuable tool for evaluating orbital trauma, offering diagnostic image quality with reduced radiation exposure.
    • The technique effectively demonstrates orbital soft-tissue injuries, aiding in the diagnosis of conditions like diplopia.
    • Multiplanar reconstructions enhance the visualization and assessment of orbital soft-tissue abnormalities.
