Quantitative Comparison of Virtual and True Noncontrast Lung Images in Photon-counting CT: Global and Regional Attenuation Assessment.
Background Use of virtual noncontrast (VNC) images from photon-counting CT (PCCT) may reduce radiation dose and support quantitative lung analysis by obviating the need for separate true noncontrast (TNC) acquisitions. Their accuracy for lung densitometry, however, has not been systematically assessed. Purpose To evalu...
