Quantification of airway wall contrast enhancement on virtual monoenergetic images from spectral computed tomography

1

Quantitative post-processing of CT is crucial for assessing lung abnormalities in various inflammatory airway diseases.
2

Contrast material can alter lung density and airway dimension measurements, making non-enhanced CT acquisitions generally recommended.
3

Spectral detector CT allows for the production of iodine maps and virtual monoenergetic images for enhanced assessment of airway wall contrast.
4

This study analyzed lung parenchyma and airway wall attenuation across different energy levels in healthy individuals using spectral CT.
5

A total of 234 patients were included, with both non-enhanced and contrast-enhanced spectral CT scans evaluated for lung and airway wall enhancement.
