introduction: the preoperative diagnostic evaluation of the parotid lesion is a valuable aid in planning the operation and the approach to intervention. among different diagnostic tools, fine needle aspiration has a key role. however, the exact efficacy of this technique in our center had not been thoroughly investigated. materials and methods: between january 2000 and june 2007 a subset of 64 ...

Background and Objectives: Thyroid gland because of its superficial location is amenable to direct physical examination. Clinical assessment of thyroid lesions by means of physical examination, thyroid scans and ultrasonography is not completely reliable. Fine needle aspiration cytology (FNAC) is the most cost-effective, safe and an initial diagnostic test in the pre-operative evaluation of thy...

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...

BACKGROUND The comparison between endoscopic ultrasound guided fine needle aspiration (EUS-FNA) and endoscopic ultrasound guided fine needle biopsy (EUS-FNB) for the diagnosis of pancreatic masses is still controversial. Many factors can affect the final results. METHODS Databases, such as PubMed, EMBASE, Cochrane Library, and Science Citation Index updated from 2000 to 2016 were searched to ...

AIM To analyze the diagnostic accuracy of telediagnostic procedures for transbronchial fine needle aspirations. MATERIAL AND METHODS A double blind study was performed on cytological slides of 54 randomly selected cases with transbronchial fine needle aspirations. The slides were digitized using a Leica digital camera DC100 mounted on a microscope Leica Laborlux S, and analyzed by an experien...

BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a widely-accepted method for obtaining both benign and malignant mediastinal lymph node samples. We present the results obtained with a modification that simplifies sampling, known as fine-needle capillary sampling or EBUS-FNC. METHODS A prospective observational study with 44 consecutive patients who u...
