BACKGROUND Despite known benefits to needle biopsy for suspicious breast lesions, variability in the use of this technique has been documented in practice. We sought to study the use of needle biopsy and open surgical biopsy in women with breast cancer, predictors of needle biopsy use, and the effect of biopsy choice on overall number of surgical procedures needed to treat breast cancer. METH...

Using testicular spermatozoa from either open biopsy (29 cycles) or biopty gun needle biopsy (49 cycles), a total of 81 intracytoplasmic sperm injection (ICSI) cycles among 57 couples were carried out from January, 1994 to September, 1997. In six cycles, no spermatozoa were obtained, and in three cycles spermatozoa from both needle and open biopsies were used. The fertilization (37% after open ...

BACKGROUND Core needle biopsy is a relatively new technique used to diagnose salivary gland lesions, and its role in comparison with fine needle aspiration cytology needs to be refined. METHODS We compared the results of 228 ultrasound-guided core needle biopsy and 371 fine needle aspiration procedures performed on major salivary gland tumors with their postoperative histological diagnoses. ...

BACKGROUND AND PURPOSE Diagnostic test accuracy studies for ultrasonography-guided fine-needle aspiration and ultrasonography-guided core needle biopsy have shown inconclusive results due to their heterogenous study designs. Our aim was to compare the diagnostic accuracy of ultrasonography-guided fine-needle aspiration versus ultrasonography-guided core needle biopsy for detecting malignant tum...

Introduction. Needle biopsy, including core needle biopsy (CNB) and vacuum-assisted breast (VABB) with or without radiological support) is the initial investigative method of choice for preoperative diagnosis lesions. Ultrasound-guided VABB (US-VABB) has become widely accepted because its high accuracy. In this review, diagnostic performance indices CNB were compared US-VABBB techniques.

BACKGROUND Controversy exists over whether or not single-needle liver biopsies are sufficient to compare histological parameters in patients with non-alcoholic fatty liver disease. AIMS To identify sampling variability, we biopsied four liver specimens per patient, based on biopsy size (needle vs wedge) and location (left vs right lobe), immediately prior to bariatric Roux-en-Y gastric bypass...

Endoscopic ultrasound is an important innovation in the field of gastrointestinal endoscopy and allows evaluation of many organs in the vicinity of the gastrointestinal tract. Endoscopic ultrasound-fine needle aspiration has been established to be an important tool in the management of pancreaticobiliary disease and is used for screening, staging, biopsy confirmation, and palliation. The accura...

Objectives: Ultrasound-guided synovial biopsy is increasingly applied in rheumatology. Usually forcepsor needle-based techniques are used. So far there has been no direct comparison of different devices regarding their suitability in high resolution musculoskeletal ultrasound (hrMSUS)-guided synovial biopsy. Methods: A core needle biopsy (Quickcore, Cook Medical, Bloomington, IN, USA), an anter...
