Key Points

The research aims to establish cut-off values for superior mediastinal width to enable early detection of thoracic aortic diseases.
Retrospective analysis of 152 subjects with both CTA and chest radiographs.
Measurements of superior mediastinal width at three levels on chest radiographs.
Categorization of thoracic CTA findings into normal and abnormal groups.
Calculation of cut-off values using ROC curve analysis.
Optimal cut-off value for mediastinal width identified at ≥ 8.4 cm at the aortic knob level.
ROC analysis indicates a sensitivity of 77.3% for the identified cut-off.
Statistically significant findings indicating potential for early disease detection.
