OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration could be performed better with computer-based preparation. METHODS Three-dimensional virtual bronchoscopy was used to develop 2 modes of computer-based "virtual endobronchial ultrasound." "Virtual endobronchial ultrasound standard" used conventional virtual bronchoscopy to determine the spot and angle for transbronchia...

OBJECTIVE Mediastinoscopy as diagnostic procedure for evaluation of mediastinum in patients with non-small-cell lung cancer has long been considered the reference standard. However, less invasive method has occurred. Endobronchial ultrasound-guided transbronchial needle aspiration came into widespread use and has resulted in controversy as to whether it is a good replacement for mediastinoscopy...

BACKGROUND AND PURPOSE Washout thyroglobulin provides evidence for metastatic or recurrent lesions, However, the cutoff value is still controversial. We investigated an optimized cutoff value and indication for the use of washout thyroglobulin from fine-needle aspiration in neck lymph nodes from preoperative or postoperative patients with well-differentiated thyroid cancers. MATERIALS AND MET...

BACKGROUND Hitherto uncommon, the incidence of extracranial metastases of primary brain malignancies may increase, with improved treatment methods and longer patient survival. Fine needle aspiration biopsy is a simple, safe and reliable method to diagnose metastatic malignancy. It has definite advantages over tissue biopsy, which is more invasive and is of higher risk to the patient. Ours is a ...

Introduction Fine Needle aspiration cytology (FNAC) is currently practiced worldwide.Fine aspiration cytology has proven to be an effective first line diagnostic tool in evaluating palpable thyroid lesions. It allows better selection of the patients who need to undergo a surgical procedure (1). However, in most of thyroid lesions, an unsatisfactory specimen, especially mixed with blood, poses a...

Posterior interosseous nerve palsy caused by a ganglion is not common and most previous patients were treated with excisional surgery. We treated a case conservatively with needle aspiration using ultrasonography, after a nerve conduction study. A 77-year-old man presented with impaired active finger extension of the left metacarpophalangeal joints. The nerve conduction study revealed conductio...

Communications to the Editor are basically in agreement with his statements, we feel a few comments are in order. The extremely high rate of specific benign diagnoses reported by Khouri et al’ from needle biopsies of lung nodules is not the experience of most practitioners, and is probably due to their unique expertise, as well as the fact that in most instances they used an 18 or 20 ga needle ...

Introduction. Primary amyloidosis is a disorder resulting from the deposition of fibrillary protein in extracellular tissue. Diagnosis of primary amyloidosis in the celiac/para-pancreatic lymph nodes via endoscopic ultrasound-guided fine needle aspiration has not been reported in the literature. In this article, we report our first observation. Our patient is a 64-year-old Caucasian man who was...
