New lung biopsy method aims for safer, more accurate diagnosis

This study tests if using a confocal laser microscope along with a freezing probe (cryoprobe) makes lung biopsies safer and more accurate. Forty adults with lung spots will be split into two groups: one gets the standard ultrasound-guided biopsy, the other gets the new laser-guided method. The goal is to see if the new method causes fewer side effects and gets better tissue samples for diagnosis.
