endobronchial ultrasonography

Abbreviation: EBUS
The fitting of a bronchoscope with an ultrasound transducer to identify masses adjacent to the bronchi. EBUS has been used to improve the diagnostic yield of transbronchial lung biopsies and needle aspiration in patients suspected of having lung cancer and sarcoidosis.

In a prospective study, EBUS proved to be superior to CT scan in showing airway involvement by lung cancers32.
Role in assessment of mediastinal, intrapulmonary and endobronchial lesions: The EBUS has made it possible for the physicians to visualize, sample and diagnose various mediastinal abnormalities40 including sarcoidosis41 and mediastinal lymphoma37.
The EBUS provides useful supplementary information during various interventions including resection of endobronchial lesion, stricture dilatation, stenting, laser therapy, and argon plasma coagulation43.
The end diagnosis made by conventional TBNA was tuberculosis in 13 of 20 cases (65%) cytologically [24], whereas in our study the diagnostic value of EBUS TBNA was 60% in tuberculosis (6 out of 10).
4%) were successfully diagnosed by EBUS guided TBNA with a 22-gauge needle.
EBUS elastography with a strain ratio cut-off of ≥32.
In summary, this study showed that EBUS elastography, especially the stain ratio, is more accurate than traditional EBUS imaging for distinguishing malignancies in the hilar and mediastinal lymph nodes of lung cancers.
