CT-based quantification of trachea shape to detect invasion by thyroid cancer

ConclusionsGeometric moments and bounding shape features can quantify the tracheal shape and are reliable for identifying DTC tracheal invasion. The selected features quantified the extent of tracheal deformity in DTC patients with and without tracheal invasion.Clinical relevance statementSix geometric features provide a non-invasive, semi-automated evaluation of the tracheal invasion status of thyroid cancer.Key Points• A novel method for quantifying tracheal shape using 56 geometric moments and 60 bounding shape features was developed.• Six features identify tracheal invasion by thyroid carcinoma.• The selected features quantified the extent of tracheal deformity in differentiated thyroid carcinoma patients with and without tracheal invasion.
