Purpose To investigate the feasibility of low-dose positron emission mammography (PEM) concurrently to MRI identify breast cancer and determine its local extent. Materials Methods In this research ethics board–approved prospective study, participants newly diagnosed with concurrent acquisitions were assigned independently density, tumor size, histopathologic subtype undergo PEM up 185 MBq fluorine 18–labeled fluorodeoxyglucose (18F-FDG). Two radiologists, unaware location, reviewed images...
Background The diagnostic value of screening the contralateral breast with MRI in patients newly diagnosed cancer is poorly understood. Purpose To assess impact for on long-term outcomes and to determine whether subgroups unfavorable prognoses would benefit from terms survival. Materials Methods Data consecutive seen January 2008 December 2010 were reviewed retrospectively. Patients neoadjuvant chemotherapy, previous cancer, distant metastasis, absence mammography at diagnosis, no planned...
Abstract BACKGROUND: Recommendation for breast magnetic resonance imaging (MRI) screening women with a prior history of chest radiation is currently based on expert opinion, because existing data are very scant. The objective this study was to evaluate added cancer yield MRI in population. METHODS: A retrospective review identified 98 therapy who had mammography and performed at the authors' institution between January 2004 July 2010. Medical records these patients results 558 studies (296...
Purpose: Breast arterial calcifications (BAC) are not routinely reported on mammography but linked to coronary artery calcification (CAC) and cardiovascular disease (CVD) events. We sought assess primary care provider (PCP) follow-up after BAC CAC notification the association between CT. Methods: Participants without known CVD undergoing at a single centre were prospectively recruited over 18 months. qualitatively scored (none/mild/moderate/severe) by 2 breast radiologists. All participants...
OBJETIVO: Avaliar artigos, na literatura, que verificam o valor preditivo positivo das categorias 3, 4 e 5 do Breast Imaging Reporting and Data System (BI-RADS®). MATERIAIS E MÉTODOS: Foi realizada pesquisa base de dados Medline utilizando os termos "predictive value" "BI-RADS". Foram incluídos 11 artigos nesta revisão. RESULTADOS: O variou entre 0% 8%, 4% 62%, 54% 100%, respectivamente. Três avaliaram, concomitantemente, critérios morfológicos lesões apresentaram maior mamografia, sendo...
The aim of this study is to evaluate the performance Radialis organ-targeted positron emission tomography (PET) Camera with standardized tests and through assessment clinical-imaging results. Sensitivity, count-rate performance, spatial resolution were evaluated according National Electrical Manufacturers Association (NEMA) NU-4 standards, necessary modifications accommodate planar detector design. detectability small objects was shown micro hotspot phantom images. clinical camera also...
The Canadian Association of Radiologists (CAR) Breast Disease Expert Panel consists breast imaging radiologists, a high-risk clinician, patient advisor, and an epidemiologist/guideline methodologist. After developing list 20 clinical/diagnostic scenarios, systematic rapid scoping review was undertaken to identify systematically produced referral guidelines that provide recommendations for one or more these scenarios. Recommendations from 30 contextualization criteria in the Grading...
Background: Breast arterial calcification (BAC) on mammography correlates with increased cardiovascular risk. Reporting BAC is not standard practice. Our study evaluates the awareness of Canadian radiologists who report clinical significance and their attitudes towards reporting compared to European American counterparts. Methods: Following local institutional ethics approval, a 25 question survey (SurveyMonkey) was disseminated via provincial national society email lists. Responses were...
Introduction A newly developed clinical organ-targeted Positron Emission Tomography (PET) system (also known as Radialis PET) is tested with a set of standardized and custom tests previously used to evaluate the performance Mammography (PEM) systems. Methods Imaging characteristics impacting uptake value (SUV) detectability small lesions, namely spatial resolution, linearity, uniformity, recovery coefficients, are evaluated. Results In-plane resolution was measured 2.3 mm ± 0.1 mm, accuracy...
Contrast-enhanced breast magnetic resonance imaging (MRI) is currently recommended as a screening tool for high-risk women and has been advocated with radiologically dense tissue. While MRI acknowledged its high sensitivity (with an exception lower-grade ductal carcinoma in situ (DCIS) where emerging techniques like diffusion-weighted offer improvement), limitations include to hormonal changes relatively false-positive rate, potentially leading overdiagnosis, increased uncertainty,...
