Evaluating non-contrast 3D reconstructions for pulmonary segmentectomy: a reliable alternative to contrast-enhanced models in thoracic surgery.

ABSTRACT:

Background

Thoracoscopic segmentectomy is increasingly used to treat early-stage non-small cell lung cancer (NSCLC) due to its ability to preserve pulmonary function and maintain quality of life. Preoperative three-dimensional (3D) reconstructions are essential for planning this procedure, particularly for identifying anatomical variations and ensuring precise resections. While intravenous (contrast-enhanced) (IV) 3D models are the gold standard, they are associated with risks such as allergic reactions, renal impairment, and logistical challenges. The aim of this study was to evaluate whether non-intravenous (non-contrast imaging) (NIV) 3D models can provide an anatomically reliable alternative to IV-based models for preoperative planning in pulmonary segmentectomy.
