Stereotactic vacuum-assisted breast biopsy (VAB) has been used to evaluate microcalcifications or non-palpable breast lesions on mammography. Although stereotactic VAB is usually performed in a prone or upright position, an expensive prone table is necessary and vasovagal reactions often occur during the procedure. For these reasons, the lateral decubitus position can be applied for stereotacti...

Purpose. To evaluate the correlation between MRI and histopathological findings in patients with mammographically detected 3-5 BI-RAD (Breast Imaging Reporting And Data Systems) microcalcifications and to allow a better surgical planning. Materials and Method. 62 female Patients (age 50 ± 12) with screening detected 3-5 BI-RAD microcalcifications underwent dynamic 3 T contrast-enhanced breast ...

AIM A retrospective analysis of 126 consecutive computed tomography (CT)-guided, frame-based stereotactic procedures in 121 patients is presented to evaluate the diagnostic yield, accuracy, complications, management of non-diagnostic cases and followup. MATERIAL AND METHODS The medical records of the identified patients were investigated retrospectively. Age, sex, surgical procedures, histopa...

RATIONALE The aim of the study was to evaluate stereotactic biopsy for diagnosing intracranial lesions in patients with AIDS. PATIENT CONCERNS Seven AIDS patients with an intracranial lesion who underwent stereotactic biopsy were included in this retrospective study (4 males and 3 females, 15 to 49 years old). The patients' disease history ranged from 1 month to 1 year. The samples were exami...

Focal brain lesions (FBL) in HIV-infected patients remain a diagnostic dilemma. Approximately 30-40% of all patients with AIDS show central nervous system (CNS) disease [1,2]. This number increases to 75% or more in autopsy studies. Approximately 10% of AIDS patients with CNS disease have one or more mass lesions [2]. The differential diagnosis of these mass lesions is broad and can include pri...

OBJECTIVE Despite the growing popularity of frameless image-guided surgery systems, stereotactic frame systems are widely accepted by neurosurgeons and are commonly used to perform biopsies, functional procedures, and stereotactic radiosurgery. We investigated the accuracy of the Brown-Roberts-Wells stereotactic frame system when the mechanical load on the frame changes between preoperative ima...
