the evaluate the diagnostic value of image guided fine needle aspiration (fna) in breast lesions, the cytologic results of 401 patients were studied. all patients had either unpalpable masses or lesions who were hardly possible to localize by palpation and fna was performed by single radiologist under ultrasound guide in all cases. the cytologic results were divided into four categories (inconc...

OBJECTIVES The exact preoperative diagnosis of parotid gland masses requires highly specific and sensitive diagnostic techniques. The specificity, sensitivity and accuracy of ultrasonography guided fine needle aspiration biopsy of parotid gland masses were assessed. PATIENTS AND METHODS There were 46 female and 36 male patients. The mean age was 39 years (range 18 to 74 years). Ultrasonograph...

OBJECTIVE To study the efficacy and safety of endoscopic ultrasonography-guided fine-needle aspiration in the management of mediastinal diseases in Hong Kong. DESIGN Retrospective review of prospectively collected data. SETTING University teaching hospital, Hong Kong. PATIENTS A total of 125 consecutive patients with various mediastinal and pulmonary lesions that underwent trans-oesophage...

In daily clinical practice the diagnosis of lung cancer is often based on cytological specimens. These cytological samples are increasingly obtained by ultrasound-guided techniques with fine needle aspirations. Recent developments have shown that transesophageal ultrasound guided fine needle aspiration (EUS-FNA) and endobronchial ultrasound guided transbronchial fine needle aspiration (EBUS-TBN...

PURPOSE The purpose of this study was the clinical evaluation of ultrasound-guided biopsy in comparison with ultrasound-guided fine-needle aspiration biopsy of identical, non-palpable breast lesions. MATERIALS AND METHODS From August 1997 until July 1998, 73 ultrasound-guided biopsies were performed in 66 patients with non-palpable lesions of the breast. In 18 patients (age 33-77 years) with ...

Objectives The Papanicolaou Society of Cytopathology’s terminology scheme for endoscopic ultrasound-guided fine needle aspiration cytology includes an ‘atypical’ interpretation category. We conducted a retrospective study to determine the frequency of its use within our institution and the interobserver agreement among pathologists with variable experience in interpretation. Methods Following I...

Endoscopic ultrasound-guided fine needle aspiration-biopsy is a safe and effective technique in diagnosing and staging of pancreatic ductal adenocarcinoma. However its predictive negative value does not exceed 50% to 60%. Unfortunately, the majority of pancreatic cancer patients have a metastatic and/or a locally advanced disease (i.e., not eligible for curative resection) which explains the li...

Computed tomography (CT) allows the performance of fine needle aspiration biopsies in situations in which ultrasound or conventional X rays do not correctly visualize the lesion or the needle tract. One hundred four patients with a clinical suspicion of neoplasia were subjected to CT guided percutaneous aspiration biopsies in a lapse of 6 years. The most frequently biopsied organs were the lung...
