Convex‐Probe Ultrasonography in Flexible Bronchoscopy
Bibliographic record
Abstract
Despite the advances in diagnostic bronchoscopy that were made with the introduction of conventional transbronchial needle aspiration (TBNA) and radial probe endobronchial ultrasound (EBUS), their respective limitations prompted the development of convex-probe-EBUS (CP-EBUS) which allowed real-time ultrasound guidance of the TBNA procedure. EBUS-TBNA may be performed in clinical environments similar to that of traditional bronchoscopy. This includes endoscopy rooms, dedicated interventional pulmonology suites, and operating rooms. When invasive mediastinal staging is indicated, EBUS-TBNA has been shown to have greater diagnostic accuracy in mediastinal staging of lung cancer compared with computed tomography and fluorodeoxyglucose positron emission tomography. A limitation of the current generation of CP-EBUS bronchoscopes is the relatively large diameter and reduced flex angle which limit access to the proximal airways. In the age of minimally invasive diagnostic and therapeutic technology, the possible applications of CP-EBUS are numerous and represent an exciting future for a game-changing procedure.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
