CT fluoroscopy for thoracic interventional procedures

In the past several years, CT fluoroscopy has proved a valuable new techniq ue in guiding the performance of intrathoracic procedures. Several approach es to using CT fluoroscopy are discussed. We have found an interrupted, rea l-time technique optimal to facilitate biopsy of percutaneous lung nodules, particularly small lesions. The technique is also valuable in assisting th oracic drainage procedures. This article also discusses the use of CT fluor oscopy to guide transbronchial needle aspiration, which is another potentia lly important application.
