An imaging-guided core needle biopsy has been proven to be reliable and accurate for the diagnosis of both benign and malignant diseases of the breast, and has replaced surgical biopsy. However, the possibility of a false-negative biopsy still remains. Imaging-pathology correlation is of critical importance in imaging-guided breast biopsies to detect such a possible sampling error and avoid a d...
The aim of the present study was to investigate whether imprint cytology can improve the diagnostic accuracy of computed tomography-guided transthoracic core biopsy. Between October 1997 and June 2004, thoracic lesions in 622 patients underwent biopsy using 19-gauge coaxial guiding needles and 20-gauge biopsy needles under computed tomography guidance. Touch imprint cytology and histopathology ...
In recent times, the diagnosis of breast lesions has mostly become dependent on core needle biopsies (CNBs) with a gradual reduction in the rate of performing fine-needle aspiration cytology (FNAC). Both the procedures have their pros and cons and outsmart each other taking into account different parameters. Both the methods are found to be fraught with loopholes, taking into account different ...
Aim The aim of the study was to review two techniques that can be used to verify focal lesions in the breasts: fine-needle aspiration biopsy and core-needle biopsy. Material and methods Fifty-five articles (original papers and reviews), half of them published within the past 5 years, were included in the analysis. The authors also took their own experience into account. Results Pre-operativ...
PURPOSE To determine the frequency with which ultrasonographically (US) guided core biopsy obviated diagnostic surgical biopsy of nonpalpable breast masses, to calculate the cost savings of diagnosis attributable to US-guided core biopsy, and to compare the costs of US-guided versus stereotactically guided core biopsy. MATERIALS AND METHODS US-guided core biopsy was performed in 151 consecuti...
Incidence of breast cancer is increasing in developing countries. The chances of cure are related to early diagnosis. In recent years there has been increased use of core needle biopsy for preoperative diagnosis of breast lesions. Seventy one patients, who were diagnosed to have infiltrating ductal carcinoma on fine needle cytology and for whom core needle biopsy was done were taken up for the ...
HYPOTHESIS The incidence of sentinel node (SN) metastases from invasive breast cancer might be affected by the technique used to obtain biopsy specimens from the primary tumor before sentinel lymph node dissection. DESIGN Prospective database study. SETTING The John Wayne Cancer Institute. PATIENTS AND METHODS We identified 663 patients with biopsy-proven invasive breast cancer who underw...
A pathological diagnosis of pulmonary Langerhans cell histiocytosis (PLCH) usually requires a surgical lung biopsy. To date, diagnosis of PLCH by core needle biopsy has not been reported. Three cases are presented of PLCH diagnosed by CT-guided core biopsy in adult female smokers found to have multiple small bilateral lung nodules. The nodules biopsied were 5 mm, 7 mm and 1 cm in size, and show...
BACKGROUND The purpose of this study was to determine the yield of stereotactic core breast biopsy and its cost-saving potential. METHODS This observational study was conducted at the Department of Radiology at Aga Khan Hospital in Karachi. All female patients (n = 84) undergoing stereotactic core breast biopsy under mammographic guidance from January 2005 to May 2010 were included. Stereotac...
