Blind Source Separation (BSS) is a powerful tool for analyzing composite data patterns in many areas, such as computational biology. We introduce a novel BSS method, Convex Analysis of Mixtures (CAM), for separating non-negative well-grounded sources, which learns the mixing matrix by identifying the lateral edges of the convex data scatter plot. We propose and prove a sufficient and necessary condition for identifying the mixing matrix through edge detection in the noise-free case, which enables CAM to identify the mixing matrix not only in the exact-determined and over-determined scenarios, but also in the under-determined scenario...

PURPOSE: Stringent quality assurance is required in MRI breast screening to ensure that different scanners and imaging protocols reach similar diagnostic performance. The authors propose a methodology, based on power spectrum analysis (PSA), to evaluate spatial resolution in clinical images. To demonstrate this approach, the authors have retrospectively compared two MRI sequences commonly employed in breast screening. METHODS: In a novel approach to PSA, spatial frequency response curves (SFRCs) were extracted from the images...

OBJECTIVE: Currently, dynamic contrast-enhanced (DCE) breast magnetic resonance imaging (MRI) prioritizes spatial resolution over temporal resolution given the limitations of acquisition techniques. The purpose of our intrapatient study was to assess the ability of a novel high spatial and high temporal resolution DCE breast MRI method to maintain image quality compared with the clinical standard-of-care (SOC) MRI. MATERIALS AND METHODS: Thirty patients, each demonstrating a focal area of enhancement (29 benign, 1 cancer) on their SOC MRI, consented to undergo a research DCE breast MRI on a second date...

PURPOSE: Roughly two-thirds of early breast cancer cases are associated with negative axillary nodes and do not benefit from axillary surgery at all. Accordingly, there is an ongoing search for non-surgical staging procedures to avoid lymph-node dissection or sentinel node biopsy (SNB). Non-invasive imaging techniques with very high sensitivity (Se) and negative predictive value (NPV) could eventually replace SNB. We aimed to establish the role of axillary US and MRI, alone or in combination, associated with ultrasound-guided fine-needle aspiration biopsy (US-FNAB) in the prediction of axillary node involvement...

BACKGROUND: Dynamic contrast-enhanced magnetic resonance imaging (DCE - MRI) has been widely used in the management of breast cancer, and its diagnostic value in breast imaging has been demonstrated. There have only been a few reports regarding the usefulness of pre-contrast imaging. Knowledge about clinically significant findings of preoperative, pre-contrast T1 and T2 MR images will allow more accurate decisions regarding patient treatment and management. OBJECTIVES: The aim of this study was to evaluate the clinically significant findings of preoperative, pre-contrast T1 and T2 MR images in recently diagnosed breast cancer patients...

Desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. It has been associated with scar from previous breast surgery or trauma. Especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. We presented multimodality imaging findings (ultrasound, computed tomography, magnetic resonance imaging and positron emission tomography/computed tomography) of chest wall desmoid tumor mimicking recurrent breast cancer in a 38-year-old patient with a history of left modified mastectomy...

Purpose The primary toxicity of trastuzumab therapy for human epidermal growth factor receptor 2-overexpressing (HER2-positive) breast cancer is dose-independent cardiac dysfunction. Angiotensin-converting enzyme inhibitors and β-blockers are recommended first-line agents for heart failure. We hypothesized that angiotensin-converting enzyme inhibitors and β-blockers could prevent trastuzumab-related cardiotoxicity. Patients and Methods In this double-blinded, placebo-controlled trial, patients with HER2-positive early breast cancer were randomly assigned to receive treatment with perindopril, bisoprolol, or placebo (1:1:1) for the duration of trastuzumab adjuvant therapy...

Becker naevus syndrome is a rare epidermal naevus syndrome defined by the co-occurrence of a Becker naevus with various cutaneous, muscular and skeletal anomalies. In the majority of cases, abnormalities exclusively consist of ipsilateral hypoplasia of the breast, areola and/or nipple in addition to the naevus. Here, we report on a 42-year-old woman with an extensive Becker naevus reaching from the left buttock to the left calf verified on histological examination. In addition, there was marked hypoplasia of the fatty tissue of the left thigh confirmed by magnetic resonance imaging in contrast to hyperplasia of the fatty tissue of the left gluteal area...
