Localization of Small Peripheral Pulmonary Lesion by Methylene Blue Injection With Radial Endobronchial Ultrasonography in Sublobar Resection.

Ultrasonography can be performed as an adjunct to aid in the localization of small nodules. We describe 25 patients with computed tomographic evidence of peripheral pulmonary lesions (PPLs) who underwent bronchoscopy with endobronchial ultrasonography (EBUS) for localization. The results demonstrate that methylene blue injection with radial EBUS is a simple and easy location technique for PLLs in Sublobar resection.
