Abstract

Virtual bronchoscopic navigation (VBN) with photon-counting CT reduces radiation dose by 83% compared to energy-integrating CT, meeting the threshold for lung cancer screening and the high resolution standards required for accurate VBN https://bit.ly/3BXQ3zj

a) Relative distribution of the radiologists' assessments regarding image quality, sharpness and noise on a Likert scale from 1 (insufficient) to 5 (very good). b) Bar chart showing the average radiation dose in radiation-sensitive thoracic organs for both computed tomography modalities, along with the corresponding radiation dose reduction factor achieved by the use of photon-counting detector computed tomography (PCCT), with a five-fold reduction benchmark indicated by a red dashed line. c) Representative axial slices of lesions obtained using the virtual navigation bronchoscopy protocol, with energy-integrating detector computed tomography (EID-CT) (top) and PCCT (bottom) shown for different subjects. Lesions are located in the right upper lobe (left column) and the right lower lobe (right column), emphasising improved image quality, enhanced sharpness and reduced noise, as assessed by radiologists.
