Filter by:This pilot clinical trial studies how well cone-beam computed tomography (CBCT) works in guiding bronchoscopy in patients with lung lesions. CBCT during bronchoscopy may help doctors to biopsy lung lesions that are harder to reach.
The purpose of this study is to compare the yield of two methods for obtaining a lung tissue sample: Procedure #1: standard fiberoptic bronchoscopy (FB) with fluoroscopy, and Procedure #2: ultrathin bronchoscope procedure with fluoroscopy and radial endobronchial ultrasound (R-EBUS). These two procedures are similar in that they both: (1) enable your doctor to look inside your lungs with a device called a bronchoscope, and (2) Use fluoroscopy, which is a technique that uses X-rays to see your lungs. This will give the doctor an opportunity to use either of the bronchoscopy methods described above and compare the tests to see if R-EBUS provides better results than standard bronchoscopy.
The main purposes of this study are to assess the performance characteristics of transbronchial needle aspiration (TBNA) in the diagnosis of peripheral pulmonary lesions, and to identify the predictor variables of a positive aspirate.
