A patient with pulmonary nodules 1 year after curative intent resection of primary lung adenocarcinoma

Answer C
In one multicenter prospective, randomized controlled trial the diagnostic yield of combined REBUS with ENB was 88%, significantly better than either REBUS or ENB alone. In the combined REBUS and ENB group, navigation to the lesion was first performed using the ENB system. When the lesion was reached, the ENB sensor probe was removed and the REBUS probe was inserted through the extended working channel of the bronchoscope to confirm visualization of the target lesion.


Diagnostic sensitivity is increased when radial probe endobronchial ultrasound is combined with electromagnetic navigational bronchoscopy.
