About

Roy Joseph Cho is a leading interventional pulmonologist whose work focuses on advancing bronchoscopic techniques for diagnosing and treating pulmonary lesions. His research centers on improving the accuracy and feasibility of navigational bronchoscopy, including electromagnetic navigation (ENB) and robotic-assisted bronchoscopy (RAB), particularly for challenging parenchymal lung lesions. Cho’s major contribution is the introduction and validation of the “artery sign”—a novel pre-procedural CT-based marker that identifies a pulmonary artery branch leading to a target lesion, offering an alternative when the traditional “bronchus sign” is absent. This innovation addresses a critical gap, as up to 40% of lesions lack a clear airway pathway, potentially increasing diagnostic yield. His most-cited work, “The Feasibility of Using the ‘Artery Sign’ for Pre-Procedural Planning in Navigational Bronchoscopy” (2022, 11 citations), has already influenced procedural planning in interventional pulmonology. Cho’s impact is evident in his ability to merge radiological insights with clinical practice, enhancing the safety and efficacy of minimally invasive lung biopsies. His achievements include pioneering this concept and contributing to the evolution of precision bronchoscopy, making him a key figure in the field for researchers and clinicians alike.
