The application value of quantitative analysis of orbital soft tissue parameters on plain CT scans in evaluating the activity of thyroid-associated ophthalmopathy
To investigate the feasibility of specific quantitative metrics, such as diameters and densities, from orbital CT scans for assessing inflammatory activity status in patients with thyroid-associated ophthalmopathy (TAO).
Key Findings:
ROC curve analysis indicated diagnostic efficacy for active TAO with specific thresholds: intraorbital fat density ≥ -78.5 HU, OM/TOA ratio ≥ 0.301, and superior rectus CSA ≥ 49.115 mm2.
Interpretation:
The study demonstrates that specific quantitative measurements from CT imaging can reliably assess disease activity in TAO patients.
Limitations:
Retrospective design may introduce selection bias and confounding factors.
Conclusion:
Quantitative measurements from CT scans, particularly of the superior rectus muscle and intraorbital fat density, are reliable indicators for evaluating TAO activity, which can enhance clinical decision-making.
