BACKGROUND Oppositional defiant disorder (ODD) is characterised as a recurrent pattern of defiant behaviour towards authority figures, irritability and difficulties in regulating emotions. ODD in adolescents presents similar symptomatology to borderline personality disorder (BPD). A treatment programme that has been shown to be effective for treating problems related to emotion dysregulation su...

Digital breast tomosynthesis (DBT) images of a novel anthropomorphic breast phantom (UPenn phantom) acquired on two breast tomosynthesis systems were analyzed in terms of their power spectra (PS). The β and κ power law coefficients were estimated from 2D planar, tomosynthesis projection images and reconstructed planes. These data were compared to the PS characteristics as retrieved from a group...

OBJECTIVES The objective was to determine if digital tomosynthesis of the breast (DBT) assesses the extension of ductal carcinoma in situ (DCIS) with higher precision than mammography (MG). MATERIAL AND METHODS The local ethics committee approved this retrospective study including 26 patients with DCIS, which were rated by three radiologists. Statistics were performed using intraclass correla...

Heavy demands on the development of medical imaging modalities for breast cancer detection have been witnessed in the last three decades in an attempt to reduce the mortality associated with the disease. Recently, Digital Breast Tomosynthesis (DBT) shows its promising in the early diagnosis when lesions are small. In particular, it offers potential benefits over X-ray mammography — the current ...

PurposeTo develop a computerized detection system for the automatic classification of presence/absence mass lesions in digital breast tomosynthesis (DBT) annotated exams, based on deep convolutional neural network (DCNN).Materials and MethodsThree DCNN architectures working at image-level (DBT slice) were compared: two state-of-the-art pre-trained (AlexNet VGG19) customized through transfer lea...

RATIONALE AND OBJECTIVES Studies have demonstrated a relationship between mammographic parenchymal texture and breast cancer risk. Although promising, texture analysis in mammograms is limited by tissue superposition. Digital breast tomosynthesis (DBT) is a novel tomographic x-ray breast imaging modality that alleviates the effect of tissue superposition, offering superior parenchymal texture v...

Background This article presents a detailed idiographic analysis of Dialectical Behaviour Therapy (DBT) clinicians' experiences of team consultation meetings. DBT is an evidence-based psychological intervention with a demonstrated efficacy in the treatment of borderline personality disorder (BPD). Team consultation meetings encompass one of the primary components involved in this treatment mode...

The aim of this study was to compare the detection of microcalcification clusters by human observers in breast images using 2D-mammography and narrow (15°/15 projections) and wide (50°/25 projections) angle digital breast tomosynthesis (DBT). Simulated microcalcification clusters with a range of microcalcification diameters (125 μm-275 μm) were inserted into 6 cm thick simulated compressed brea...

A carbazole-utilizing bacterium was isolated by enrichment from petroleum-contaminated soil. The isolate, designated Sphingomonas sp. strain XLDN2-5, could utilize carbazole (CA) as the sole source of carbon, nitrogen, and energy. Washed cells of strain XLDN2-5 were shown to be capable of degrading dibenzofuran (DBF) and dibenzothiophene (DBT). Examination of metabolites suggested that XLDN2-5 ...

This paper describes a new reconstruction method for digital breast tomosynthesis (DBT). The new method incorporates detector blur into the forward model. The detector blur introduces correlation in the measurement noise. We formulate it as a regularized quadratic optimization problem with data-fit term that accounts for the non-diagonal noise covariance matrix. By making a few assumptions base...
