CONTEXT In patients with suspected lung cancer, the presence of mediastinal lymph node metastasis is a critical determinant of therapy and prognosis. Invasive staging with pathologic confirmation is recommended. Many methods for staging exist; mediastinoscopy, an invasive procedure requiring general anesthesia, is currently regarded as the diagnostic standard. OBJECTIVE To compare the diagnos...

BACKGROUND The reported reliability of core needle biopsy (CNB) is high in assessing thyroid nodules after inconclusive fine-needle aspiration (FNA) attempts. However, first-line use of CNB for nodules considered at risk by ultrasonography (US) has yet to be studied. The aim of this study were: 1) to evaluate the potential merit of using CNB first-line instead of conventional FNA in thyroid nod...

BACKGROUND Fine needle aspiration is the main diagnostic tool used to assess thyroid nodules. OBJECTIVES To correlate FNA cytology results with surgical pathological findings in two teaching medical centers across the Atlantic. METHODS We retrospectively identified 484 patients at Hadassah Hebrew University Medical Center, Jerusalem and Mount Sinai Hospital, New York, by means of both preop...

STUDY OBJECTIVE We hypothesized that transoesophageal endoscopic ultrasound guided fine needle aspiration (EUS-FNA) has the potential to be a valuable and accurate new diagnostic technique for mediastinal restaging in non-small cell lung cancer (NSCLC) after induction chemotherapy. The current restaging modalities either have a low diagnostic accuracy (computed tomography (CT) scan of the thora...

BACKGROUND The American Thyroid Association (ATA) recommends using ultrasound-guided fine-needle aspiration (FNA) in order to evaluate supracentimetric and suspect thyroid nodules. The purpose of this study was to evaluate the effective use of FNA before surgery for nodules over 3 cm in diameter. METHODS In this retrospective study, we analyzed the results of ultrasound-guided FNA and postope...

Background Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA) has become the preferred method to diagnose pancreatic masses due to its minimally invasive approach and diagnostic accuracy. Many studies have shown that rapid on-site evaluation (ROSE) improves diagnostic yield by 10-30%; however, more recent studies have demonstrated effective diagnostic accuracy rates without ROSE. O...

BACKGROUND/AIMS Small core biopsy samples can occasionally be obtained with conventional endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA). Although most studies have focused on the cytological analysis of specimens, data regarding histological assessment is scarce. The aim of this study was to determine whether core biopsies by conventional EUS-FNA could increase the accuracy ...

OBJECTIVE The purpose of this study was to evaluate whether ultrasound elastography performed by using carotid pulsation as a compression source and generating the systolic thyroid stiffness index (STSI) can be used as a pre-fine-needle aspiration (FNA) screening tool. METHODS Ultrasound data previously acquired from 62 thyroid nodules in 59 patients who underwent a thyroid FNA were used. Pul...

OBJECTIVE Few studies have modelled the economics of thyroid FNA. METHODS A simple spreadsheet economic model for delivery of thyroid fine needle aspiration (FNA) cytology is described using the UK Royal College of Pathologists' Classification for thyroid FNA which is based on The Bethesda System for Reporting Thyroid Cytopathology. RESULTS We show an estimated 27.8% cost treatment reductio...

Fine-needle aspiration (FNA) of inflammatory and neoplastic head and neck masses has become a widely used procedure in otolaryngology-head and neck surgery. Using both subjective (patient perception) and objective (complication rate, accuracy) criteria, this prospective study evaluated patients undergoing FNA with and without anesthesia. Seventy-five patients were enrolled into 1 of 3 study gro...
