The Usefulness of Ultrasound-Guided Core Needle Biopsy Compared to Fine Needle Aspiration in Pre-Operative Diagnosis of Cystic-Predominant Parotid Tumors

Needle Core Biopsy Should Replace Fine Needle Aspiration Cytology in Breast Lesions Diagnosis

Endoscopic Ultrasound-Guided Fine-Needle Aspiration Vs Fine-Needle Biopsy.

RM The primary goal of fine-needle aspiration is to acquire individual cells as opposed to tissue, which is the aim of fine-needle biopsy. Cells may not necessarily provide the stroma, or the associated architecture, of the surrounding tissue. Thus, if the surrounding architecture is needed to make a diagnosis, a fine-needle biopsy, which typically uses a core biopsy needle, should provide that.

Concordance Rate between Fine Needle Aspiration Biopsy and Core Needle Biopsy in Breast Lesions

Background and Objectives:Breast cancer is the most common cancer among women worldwide. Fine needle aspiration biopsy (FNAB) is one of the methods of breast biopsy which is fast, easy and cost effective. The aim of this study was to evaluate the concordance rate between pathologic results of sonography or stereotaxy guided FNAB and guided core needle biopsy (CNB) in the evaluation of breast le...

Endoscopic Ultrasound-Guided Fine Needle Aspiration Accurately Diagnoses Smaller Pancreatic Neuroendocrine Tumors Compared To Computer Tomography-Guided Fine Needle Aspiration.

Introduction The role of EUS-guided FNA as a highly sensitive modality in the diagnosis of pancreatic adenocarcinoma is well documented. However, there is little published data on the role of EUS-FNA in diagnosing pancreatic neuroendocrine tumors (NETs). Objective The aim of this study is to compare the sensitivity of EUS-FNA to that of CT-FNA for diagnosing pancreatic NETs. Methods This is...

Ultrasonography guided fine needle aspiration biopsy of parotid gland masses.

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...
