Background The diagnostic yield of endoscopic ultrasound (EUS) guided fine-needle aspiration (FNA) is variable, and partly dependent upon rapid onsite evaluation (ROSE) by a cytopathologist. Second generation fine-needle biopsy (FNB) needles are being increasingly used to obtain core histological tissue samples. Aims Studies comparing the diagnostic yield of EUS guided FNA versus FNB have reach...

Diagnostic Yield Characterization Expert (DYCE) is a knowledge based system shell used for automated data interpretation in semiconductor manufacturing. Using a combination of artificial intelligence techniques , DYCE assists manufacturing and development personnel to diagnose problems by automatically interpreting hundreds of pieces of data, just as a human expert would do. Diagnosis time has ...

adequate therapy (34). Stereotactic surgery started with the Horsley-Clarke apparatus in 1908 (14). After the introduction of stereotactic surgery in human patients by Spiegel and Wycis in 1947, this approach has been used safely and effectively to obtain tissue diagnosis for intracranial lesions. There are many papers establishing the issues related to the safety, accuracy and diagnostic yield...

BACKGROUND Radial-probe endobronchial ultrasound (rEBUS)-guided transbronchial biopsy (TBB) is invaluable in the diagnosis of peripheral pulmonary lesions (PPLs); however, in certain instances, the procedure has to be repeated because of initial non-diagnostic procedure(s). Little if any literature has been published on this issue. Therefore, the aim of this study was to investigate the utility...

INTRODUCTION Since the National Lung Screening Trial demonstrated the utility of low-dose computed tomography screening for lung cancer, the detection rate of ground-glass nodules (GGNs) has increased. Endobronchial ultrasound with a guide sheath (EBUS-GS) is widely performed to diagnose peripheral pulmonary lesions, but there are not enough reports on the predictive ability of EBUS-GS in diagn...
