background: the purpose of this study was to evaluate the results of stereotactic breast core needle biopsy in a tertiary breast center of tehran university of medical sciences. methods: patients who were candidates for mammography-guided stereotactic breast core biopsy from march 2011 to december 2013 were included in this study. stereotactic biopsy was performed by a dedicated prone hologic m...

OBJECTIVES Stereotactic biopsy is a suitable method for sampling intrinsic brain lesions. Although this method is considered to be a safe procedure, some risk of complications still exists. The aim of the study was to retrospectively assess the morbidity and mortality of MRI-guided stereotactic biopsy of lesions which were histologically proven to be brain lymphoma. METHODS We retrospectively...

OBJECTIVE To evaluate our initial experience with a cone-beam breast computed tomography (BCT)-guided breast biopsy system for lesion retrieval in phantom studies for use with a cone-beam BCT imaging system. MATERIALS AND METHODS Under the Institutional Review Board approval, a phantom biopsy study was performed using a dedicated BCT-guided biopsy system. Fifteen biopsies were performed on ea...

objective(s):p in vitro chemosensitivity and resistance assays (csras) are a promising tool for personalized treatment of glioblastoma multiform (gbm). these assays require a minimum of 1 to 2 g of tumor specimen for testing, but this amount is not always accessible. we aimed to assess the feasibility and validity of utilizing stereotactic biopsies of gbm in csras. materials and methods: single...

BACKGROUND Stereotactic biopsy for brainstem lesion offers high diagnostic yield with low morbidity. We compared two modalities of biopsy procedure, frame-based and frameless stereotaxy, either transfrontal or transcerebellar route. The benefits and operation considerations are discussed. METHODS Ten patients with intrinsic brainstem lesion diagnosed with stereotactic biopsy from August 2006 ...

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...

PURPOSE To determine the cost savings of stereotactic core needle biopsy over open surgical biopsy in patient subgroups defined according to mammographic findings. MATERIALS AND METHODS From July 1992 through February 1995, stereotactic core needle biopsy was performed in 356 women with 405 nonpalpable breast lesions (254 were masses and 151 were calcification). Lesions were classified accord...

adequate therapy (34). Stereotactic surgery started with the Horsley-Clarke apparatus in 1908 (14). After the introduction of stereotactic surgery in human patients by Spiegel and Wycis in 1947, this approach has been used safely and effectively to obtain tissue diagnosis for intracranial lesions. There are many papers establishing the issues related to the safety, accuracy and diagnostic yield...
