Robot-assisted navigation system for CT-guided percutaneous lung tumour procedures: our initial experience in Hong Kong

Abstract

Materials and methods Imaging-guided lung procedures are usually challenging due to patient breathing. This is an ongoing prospective study with 50 patients targeted in a university-based hospital. This was an initial assessment of efficacy involving 10 patients with lung tumours who underwent CT-guided lung interventions utilizing the robot-assisted Navigation system (Maxio, Perfint Healthcare, USA). The targeted needle pathway was planned on Maxio Robotic system based on pre-procedural CT-scans. The primary endpoint was satisfactory instrument position for intended intervention. Lesion size and depth from skin were noted. Performance level was documented on a five-point scale (5-1: excellent-poor). Total radiation doses were recorded and compared against 20 patients with conventional CTguidance and CT-fluoroscopy lung procedures (ratio 1:1).
