Abstract
Background: Use of virtual monoenergetic images (VMIs) from multi-energy CT scans can mitigate inconsistencies in traditional attenuation measurements that result from variation in scan-related factors. Photon-counting detector (PCD) CT systems produce VMIs as standard image output under flexible scanning conditions.
