O-arm CT for Confirmation of Successful Navigation During Robotic Assisted Bronchoscopy

Area of Science:

• Pulmonology
• Medical Imaging
• Robotic Surgery

Background:

• Robotic assisted bronchoscopy (RAB) improves access to difficult pulmonary lesions.
• Computed tomography (CT) to body divergence is a limitation in RAB.
• Real-time imaging, like cone beam CT, aids navigation and tool confirmation.

Purpose of the Study:

• To evaluate the feasibility, ease of use, and tool-in-lesion confirmation rate of O-arm CT during RAB.
• To assess O-arm CT as an alternative 3D imaging modality for RAB.

Main Methods:

• Retrospective review of 75 patients undergoing RAB with intraprocedural O-arm CT.
• Analysis of procedure time, O-arm CT usage, radiation dose, and diagnostic yield.

Main Results:

• O-arm CT confirmed tool-in-lesion in 97% of cases (77/79).
• Definitive diagnosis was achieved in 77% to 86% of cases.
• Median procedure time was 80 minutes; median radiation dose was 7.2 mSv.

Conclusions:

• O-arm CT is a feasible and convenient 3D imaging option for RAB.
• It effectively confirms tool-in-lesion during robotic assisted bronchoscopy.
• It offers a valuable alternative to existing intraprocedural imaging modalities.
