Virtual <i>vs</i>. reality in cone-beam CT-guided robotic-assisted bronchoscopy.

ABSTRACT:

Background

The diagnostic accuracy of shape-sensing robotic bronchoscopy (ssRAB) is impacted by computed tomography-to-body divergence (CTBD) due to a discrepancy between virtual and actual lesion locations. The prevalence, types, implication, and determinants of CTBD during ssRAB remain understudied. This study aimed to qualify and quantify CTBD during cone-beam computed tomography (CBCT)-guided ssRAB and identify contributing factors.

Methods

This was an analysis of a prospectively curated database of patients who underwent mobile CBCT-guided ssRAB for the sampling of parenchymal lung lesions between October 2021 and June 2022. The primary outcome was the distance and vector of target displacement between the virtual preoperative CT-based and the actual intraoperative CBCT
