Lung Cancer Endobronchial Ultrasonography (EBUS)
To provide earlier detection and accurate diagnosis and staging of lung cancer, Overlake offers an advanced diagnostic technique called endobronchial ultrasonography (EBUS). Overlake is the only hospital on the Eastside to offer EBUS.
Using a linear curved-array ultrasonic bronchoscope, EBUS allows aspiration biopsies to be performed under real-time ultrasound imaging. Our instrument has linear-scanning ultrasound imaging capability and a dedicated aspiration needle, specifically designed for diagnostic biopsies and staging in the lung. In real time, we can observe the aspiration
needle on a video monitor as well as on the ultrasound image, enabling us to much more accurately target the lymph node for diagnosis and staging.
In addition to more accurate diagnoses, there are tremendous benefits to patients including a decreased need for invasive surgery.
