Although mammography has been the gold standard for the early detection of breast cancer, if a woman has dense breast tissue, a false negative diagnosis may occur. Breast ultrasound, whether hand-held or automated, is a useful adjunct to mammography but adds extra time and cost. The primary aim was to demonstrate that our second-generation Aceso system, which combines full-field digital mammography (FFDM) and automated breast ultrasound (ABUS) in a single platform, is able to produce improved quality images that provide clinically meaningful results...

Multifunctional nanoprobe was drawing increased attention in tumor diagnosis and therapy. The simple and effective establishment of the theranostic nanoplatforms was still under urgent need. Meanwhile, the targeting ability and morphology of nanoprobe were essential for the effective endocytosis, which could further affect the diagnosis. In this work, two morphologies of nanoprobes were fabricated using gold nanorods (AuNRs) and gold nanospheres (AuNSs). Thiolated-hyaluronic acid labeled with nile blue (HS-HA-NB), a near-infrared (NIR) fluorescence dye, was coated on the surface of the gold nanoparticles to form stable nanoprobes (AuNR@HS-HA-NB, AuNS@HS-HA-NB)...

The purpose of our work was to identify imaging features of atypical apocrine lesions and determine the rate of upgrade to ductal carcinoma in situ (DCIS) or invasive carcinoma at excision after such a diagnosis on percutaneous breast biopsy. From January 1, 2006, through October 8, 2013, a total of 33,157 breast core biopsies were performed at University of Pittsburgh Medical Center. Of those, 58 (0.2%) showed atypical apocrine lesions. For 24, atypical apocrine adenosis (AAA) or atypical apocrine metaplasia (AAM) was the only risk lesion, with no known ipsilateral malignancy, and the results of excision were available...

Background: Dual plane breast augmentation is a technical variation of the submuscular plane described as a technique that reduces contour deformities due to contraction of the pectoralis major muscle and lower risk of double-bubble deformity associated with breast ptosis. Despite improvement in the aesthetic aspect, there is still no consensus whether this technique affects the function of the pectoralis major muscle. Objectives: The aim of this study was to correlate functional with volumetric changes associated with dissection of the muscle origin in submuscular breast augmentation...

BACKGROUND: Bilateral axillo-breast approach robotic thyroidectomy (BABA RT) is frequently performed and has excellent cosmetic results. However, there has been concern that subcutaneous tunneling in construction of the operation field might interfere with subsequent breast imaging. In this study, we evaluated whether BABA RT interferes with breast imaging by evaluating serial perioperative results of mammography and ultrasonography. METHODS: We selected female patients who underwent BABA RT between 2008 and 2012, and who also had mammography or ultrasonography pre- and postoperatively, and compared the results of pre- and postoperative imaging...

Although transmission-based x-ray imaging is the most commonly used imaging approach for breast cancer detection, it exhibits false negative rates higher than 15%. To improve cancer detection accuracy, x-ray coherent scatter computed tomography (CSCT) has been explored to potentially detect cancer with greater consistency. However, the 10-min scan duration of CSCT limits its possible clinical applications. The coded aperture coherent scatter spectral imaging (CACSSI) technique has been shown to reduce scan time through enabling single-angle imaging while providing high detection accuracy...
