Debakey Veterans Administration Medical Center in Houston.

He is currently serving as the medical director of the ICU at Seton Medical Center Williamson. This facility has acquired the first and only Electromagnetic Navigational Bronchoscopy in central Texas. With this new advancement in technology, Dr. Soubra is now able to provide a minimally invasive approach to diagnosing and guiding therapy for patients with lung cancer.

This specialized bronchoscopy utilizes a CT scan of the patient’s chest as a guide or roadmap (like a GPS device) to map out the lung. Dr. Soubra can then navigate through the lung safely, reaching areas previously unattainable via regular bronchoscopy. He is able to obtain biopsies and tag suspicious masses or tumors for later treatment with minimal risks compared to other, more invasive, techniques such as surgery or traditional CT-guided biopsies.

This provides patients with earlier detection and potentially more curative treatment for lung cancer.
