Summary

Computed tomography (CT) accurately images pig nasal structures, correlating well with traditional scoring methods for turbinate atrophy. This non-invasive technique offers a reliable alternative for assessing nasal health in swine.

Area of Science:

  • Veterinary Radiology
  • Swine Anatomy
  • Diagnostic Imaging

Background:

  • Turbinate atrophy in swine can impact respiratory health and performance.
  • Traditional methods for assessing turbinate atrophy are invasive and subjective.
  • Computed tomography (CT) offers a non-invasive imaging modality.

Purpose of the Study:

  • To evaluate the efficacy of computed tomography (CT) for imaging pig nasal bony structures.
  • To compare CT-based scoring of turbinate atrophy with traditional methods.
  • To assess the correlation between CT imaging and a tissue/air area ratio.

Main Methods:

  • Twenty-three 27-week-old pigs with varying stages of turbinate atrophy were included.
  • Nasal structures were scored visually on CT scans and transversal nose cuts.

  • A tissue/air area ratio was determined using density differences on CT images.

    • Main Results:

    • A highly significant positive correlation was found between visual scoring of CT images and transversal cuts (r = 0.98, p < 0.0001).
    • A highly significant negative correlation was observed between visual CT scoring and the tissue/air area ratio (r = -0.82, p < 0.0001).
    • CT imaging demonstrated strong agreement with traditional scoring methods.

    Conclusions:

    • Computed tomography (CT) is a reliable and accurate tool for assessing turbinate atrophy in pigs.
    • CT provides a non-invasive alternative to traditional scoring methods.
    • CT imaging can be used to objectively quantify nasal structure changes in swine.
