Fine-needle aspiration cytology (FNAC) is the reference diagnostic tool in patients with thyroid nodules. Because the true diagnosis is based on histopathologic findings, the final diagnosis of nodules not operated on is postponed, impacting the cost. We aimed to determine the cost of FNAC by taking account of diagnostic mistakes, failures, and follow-up of patients who did not have surgery.A M...

OBJECTIVE The purpose of our study was to provide new sonographic criteria for fine-needle aspiration biopsy of nonpalpable solid thyroid nodules. MATERIALS AND METHODS Sonographic scans of 155 nonpalpable thyroid nodules in 132 patients were prospectively classified as having positive or negative findings. Sonographic findings that suggested malignancy included microcalcifications, an irregu...

The aim of this study was to evaluate the role of fine needle aspiration cytology in the diagnosis of abdominal and retroperitoneal masses in children on this study. In 53 cases of childhood abdominal and retroperitoneal masses within a 4 year period (1998- 2001) preoperative fine needle aspiration was done under the guide of CT scan. 2 pathologists reviewed fine needle aspiration smears. I...

BACKGROUND Fine needle aspiration biopsy (FNAB) is a rapid, sensitive and inexpensive procedure for diagnosing benign and malignant palpable lesions. For lesions that are not palpable or deep seated, FNAB can be performed under the guidance of radiological imaging. Our basic objective was to evaluate the spectrum of intrathoracic lesions by using Computed Tomography guided fine needle aspiratio...

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...

The present study compared the diagnostic yield of ultrasound-assisted cutting-needle biopsy (CNB) and fine-needle aspiration biopsy (FNAB) in chest lesions. A physician performed ultrasound and FNAB with a 22-G spinal needle in all patients, directly followed by a 14-G CNB in patients without contraindication. A total of 155 consecutive lesions arising from the lung (74%), pleura (12%), medias...

BACKGROUND Breast screening is a method of detecting breast cancer at a very early stage. Most of the lesions detected by screening are not malignant. Objective of this study was to compare ultrasound guided fine needle aspiration cytology and core biopsy in the preoperative assessment of non-palpable breast lesions. METHODS The study was conducted prospectively at Department of Radiology, Sh...

BACKGROUND/AIMS Tuberculous peritonitis is prevalent in developing countries and its diagnosis is still challenging due to the lack of specific clinical characteristics and the difficulty in obtaining tissue from the peritoneum without laparoscopy. Endoscopic ultrasound - guided fine needle aspiration is emerging as the most effective and safe method for obtaining tissue from the structures sur...

Needle core biopsy (NCB), as part of triple assessment for preoperative evaluation and diagnosis of breast cancer, is now considered as an established, highly accurate method for diagnosing breast cancer that has replaced either fine needle aspiration cytology or excisional biopsy as the initial diagnostic biopsy procedures in many institutions. In addition to its primary role in establishing a...
