Endobronchial ultrasound (EBUS) is a minimally invasive medical procedure that uses ultrasound technology to visualize the airways and surrounding structures in the lungs. During the procedure, a thin, flexible tube called a bronchoscope is inserted into the lungs through the mouth or nose. The bronchoscope is equipped with an ultrasound probe that produces images of the tissues, helping doctors assess conditions like lung cancer or infections. EBUS is particularly useful for guiding biopsies, allowing healthcare providers to obtain tissue samples from lymph nodes or masses in the chest. This technique enhances diagnostic accuracy while minimizing discomfort and recovery time for patients compared to traditional surgical methods.
