OBJECTIVE To evaluate the upgrade rate and delayed false-negative results of percutaneous vacuum-assisted removal (VAR) and surgical excision in women with imaging-histologic discordance during ultrasound (US)-guided automated core needle biopsy (CNB) of the breast and to validate the role of VAR as a rebiopsy method for these discordant lesions. MATERIALS AND METHODS Percutaneous US-guided 1...
OBJECTIVE Pancreatic transplantation has been relatively uncommon until the last 2 decades, but is now an accepted therapeutic intervention for type I diabetes. Core biopsies of pancreas transplants are frequently performed to rule out rejection, which is a leading cause of graft failure. Often, it is difficult to localize the graft for biopsy by imaging. Our objective was to determine whether ...
PURPOSE Stereotactic needle breast biopsy and vacuum assisted breast biopsy have replaced wide local excision in the last decades. B3 lesions of the breast represent a particular subgroup which is difficult to manage. The purpose of the present study was to present our experience with this specific type of lesions and to examine the conformity of Princess Margaret Hospital with current recommen...
PURPOSE To determine the negative predictive value of sonographically guided 14-gauge core needle biopsy of breast masses, with detailed analysis of any false-negative cases. MATERIALS AND METHODS We reviewed 669 cases of sonographically guided 14-gauge core needle biopsies that had benign pathologic findings. Given a benign pathology on core biopsy, true-negatives had either benign pathology...
Ultrasound-guided core needle biopsy (US-CNB) is an important step in the diagnosis of musculoskeletal soft-tissue lesions. To maximize efficacy and minimize the complications of US-CNB, it is critical to collaborate with a multidisciplinary team and to understand the particular considerations of US-CNB for these lesions. The purpose of this article is to provide a systematic review and step-by...
This study reports two cases of intracystic papillary carcinoma of the breast, which had been biopsied preoperatively using a 14 gauge (14G) core biopsy needle. In each case, a needle tract containing groups of epithelial cells within granulation tissue could be identified on histology of the excised specimen. Both cases showed extracapsular tumour, which was interpreted as displacement of epit...
Background : Bone tumours are relatively uncommon. The precise incidence of specific bone tumours is not known, because many bone lesions are asymptomatic and are not biopsied. The initial work up and staging evaluation of a patient with a suspected bone tumour, particularly biopsy is a critical component of successful management. Aim :To assess the diagnostic accuracy of Fine needle aspirates ...
background and objective: computerized tomography and fluoroscopic computerized tomography are amongst the methods used for guiding needle biopsy processes; however, fluoroscopic computerized tomography demonstrates the images during the process of biopsy. this study aims to compare and contrast the success of biopsy under guide of computerized tomography and fluoroscopic computerized tomograph...
