Summary

This study aims to evaluate whether femtosecond laser imaging combined with FastLung AI model can provide intraoperative diagnostic performance that is non-inferior to standard frozen section diagnosis for pulmonary nodules or suspected pulmonary tumor lesions. Patients scheduled for lung surgery and requiring intraoperative pathological assessment will be prospectively enrolled. After tumor excision, the fresh tumor specimen will be bisected through the central plane. One half will be used for standard frozen section diagnosis, and the mirrored counterpart will be used for femtosecond laser imaging. Both diagnostic results will be compared with the final paraffin-embedded pathological diagnosis as the reference standard. The results of femtosecond laser imaging will not guide intraoperative clinical decision-making.

DIAGNOSTIC_TEST

Femtosecond Laser Imaging

Fresh surgical specimens will be examined intraoperatively using femtosecond laser imaging. The imaging results will be recorded for diagnostic performance evaluation and compared with final paraffin pathology. The results will not guide intraoperative clinical decision-making.

DIAGNOSTIC_TEST

Frozen Section Diagnosis

Fresh tumor specimens will be evaluated intraoperatively by standard frozen section pathology. After the tumor is bisected through the central plane, one half of the specimen will be submitted for frozen section diagnosis, while the mirrored counterpart will be used for femtosecond laser imaging. Frozen section diagnosis will be used for routine intraoperative clinical decision-making and will also be compared with final paraffin pathology.
