OBJECTIVE To assess retrospectively the accuracy of core needle biopsy in diagnosing papillary breast lesions and evaluate the prediction of malignant papillary lesions based on sonographic features. METHODS Review of 130 papillary lesions diagnosed on core needle biopsy (2002-2008) in 110 patients. The biopsy results were compared with final surgical pathology or evolution on imaging follow-...

Background: Tissue diagnosis of anterior mediastinal tumors is very important for making correct therapeutic decision. To evaluate the value of performing percutaneous core needle biopsy in these tumors, we decided to perform this study. Materials and Methods: CT guided core needle biopsy was performed in 17 patients with anterior mediastinal tumor during an18-month period. The biopsy specimens...

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 The aim of this study was to assess the diagnostic performance of stereotactic core needle breast biopsy using spring-loaded or vacuum-assisted techniques for impalpable microcalcification lesions in Taiwanese women. METHODS We retrospectively reviewed the data of patients who received stereotactic core needle breast biopsy for impalpable mammographic microcalcification lesions fro...

OBJECTIVE We wanted to assess the need for surgical excising papillary lesions of the breast that were diagnosed upon sonographically guided 14-gauge core needle biopsy. MATERIALS AND METHODS Sixty-nine women (age range: 25-74 years, mean age: 51.7 years) with 69 papillary lesions (4.9%) were diagnosed and followed after performing sonographically guided 14-gauge core needle biopsies. Surgica...

This communication describes a single-step electrospraying technique that generates core-shell microspheres (CSMs) with encapsulated protein as the core and an amphiphilic biodegradable polymer as the shell. The protein release profiles of the electrosprayed CSMs showed steady release kinetics over 3 weeks without a significant initial burst.
