Clinical Trial Summary

This study aims to evaluate the clinical value of mobile cone-beam CT (mCBCT) in combination with electromagnetic navigation bronchoscopy for the diagnosis of peripheral pulmonary nodules, and to explore the value of mCBCT in improving the diagnostic yield by calculating the improvement in diagnostic yield of patients before and after mCBCT adjustments.

Description:

This study is a prospective, single-arm, single-center observational clinical trial to evaluate the diagnostic value of mobile cone-beam CT (mCBCT) in combination with electromagnetic navigation bronchoscopy for the diagnosis of peripheral pulmonary nodules. The investigators will adjust the position of electromagnetic navigation bronchoscopy base on the intraoperative 3D imaging findings of mCBCT. The value of mCBCT in improving diagnostic yield is explored by comparing the diagnostic yield Post-mCBCT with that of Pre-mCBCT. The Pre-mCBCT diagnostic yield is the proportion of patients diagnosed by electromagnetic navigation bronchoscopy and with no need for adjustment after mCBCT spin confirmed "tool-in-lesion" during the procedure in all enrolled subjects. The Post-mCBCT diagnostic yield is the proportion of diagnosed patients with and without adjustment after mCBCT spin during the procedure in all enrolled subjects.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Diagnostic yield improvement ratio	Diagnostic yield improvement ratio, defined as Post-mCBCT diagnostic yield minus Pre-mCBCT diagnostic yield.; The Pre-mCBCT diagnostic yield, defined as the proportion of patients diagnosed by electromagnetic navigation bronchoscopy and without any adjustment after first time mCBCT spin during the procedure in all enrolled subjects.; The Post-mCBCT diagnostic yield, defined as the proportion of diagnosed patients including those with and without adjustment after mCBCT spin in all enrolled subjects.; Diagnostic yield was defined as all instances in which the results of bronchoscopy matched the final diagnoses.	Up to at least 6 months
Secondary	Pre-mCBCT navigational yield	The proportion of patients who was confirmed tool-in-lesion by the first time mCBCT spin and no need for further adjustment in all enrolled subjects.	Intra-procedure
Secondary	Post-mCBCT navigational yield	The proportion of patients who was confirmed tool-in-lesion with and without adjustment by mCBCT in all enrolled subjects.	Intra-procedure
Secondary	Total radiation dose	Radiation dose from procedure, measured by the dose area product (DAP), defined as the product of dose and beam area (Gy cm^2).	Intra-procedure
Secondary	Fluoroscopy time	The fluoroscopy time during the procedure.	Intra-procedure
Secondary	Adjustment time	The adjustment time during the procedure, defined as the time between the first mCBCT spin scanning to final spin scanning.	Intra-procedure
Secondary	Total operation time	The total operation time was defined as the time from bronchoscope insertion to withdrawal of the glottis.	Intra-procedure
Secondary	Factors affecting diagnostic yield	The factors affecting diagnostic yield includes the nodule nature, nodule size, nodule location, bronchus sign on CT, etc.	Up to at least 6 months
Secondary	Complication rate	The complications refer to the proportion of serious adverse events related to the procedure during or within 1 month after the operation.	Up to 1 month
