BACKGROUND Sonographic features of lymph nodes on endobronchial ultrasound (EBUS) have been shown to be useful in prediction of malignancy in mediastinum and hilum. The aim of this study was to assess the utility of morphologic features of mediastinal and/or hilar lymph nodes obtained by EBUS in patients with sarcoidosis. MATERIALS AND METHODS We(More)
BACKGROUND AND OBJECTIVES Electromagnetic navigation bronchoscopy (ENB) is a promising new technology to increase the diagnostic yield of peripheral lung and mediastinal lesions. Conventional flexible bronchoscopy has a limited yield in peripheral pulmonary lesions, even in experienced hands. Radial endobronchial ultrasound (r-EBUS) with its real-time(More)
PURPOSE We aimed to put forward the contribution of virtual bronchoscopy in the determination and diagnosis of tracheobronchial system pathologies. We compared the data obtained from PET/CT and virtual bronchoscopy (VB) with the fiberoptic bronchoscopy (FOB) data of the cases with a diagnosis or pre-diagnosis of lung tumor. MATERIALS AND METHODS A total(More)
OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a new method for the diagnosis and staging of lung disease, and its use is increasing worldwide. It has been used as a means of diagnosing lung cancer in its initial stages, and there are data supporting its use for the diagnosis of benign lung disease. The aim of this(More)
UNLABELLED BACKGROUND Multidetector computed tomography (MDCT) provides guidance for primary screening of the central airways. The aim of our study was assessing the contribution of multidetector computed tomography- two dimensional reconstruction in the management of patients with tracheobronchial stenosis prior to the procedure and during a short(More)
BACKGROUND Expiratory central airway collapse (ECAC) is abnormal central airway narrowing during expiration. ECAC involves 2 different pathophysiological entities as tracheobronchomalacia and excessive dynamic airway collapse (EDAC). Although the exact cause is unknown, chronic obstructive pulmonary disease (COPD) is frequently accompanied by ECAC. Although(More)
