“…Another important issue is the civil liability of the radiologist in the diagnosis of breast cancer by means of mammography. A study shows that the data transmitted to the to the assisting physician by means of a detailed report (28) with accurate location of possible lesions, as well as correct BI-RADS classification, minimize medical errors, thus avoiding civil liability lawsuits (49) .…”

Objective To evaluate the performance of diagnostic centers in the classification of mammography reports from an opportunistic screening undertaken by the Brazilian public health system (SUS) in the municipality of Goiânia, GO, Brazil in 2010. Materials and Methods The present ecological study analyzed data reported to the Sistema de Informação do Controle do Câncer de Mama (SISMAMA) (Breast Cancer Management Information System) by diagnostic centers involved in the mammographic screening developed by the SUS. Based on the frequency of mammograms per BI-RADS® category and on the limits established for the present study, the authors have calculated the rate of conformity for each diagnostic center. Diagnostic centers with equal rates of conformity were considered as having equal performance. Results Fifteen diagnostic centers performed mammographic studies for SUS and reported 31,198 screening mammograms. The performance of the diagnostic centers concerning BI-RADS classification has demonstrated that none of them was in conformity for all categories, one center presented conformity in five categories, two centers, in four categories, three centers, in three categories, two centers, in two categories, four centers, in one category, and three centers with no conformity. Conclusion The results of the present study demonstrate unevenness in the diagnostic centers performance in the classification of mammograms reported to SISMAMA from the opportunistic screening undertaken by SUS.

“…In such a context, mammography, ultrasonography and magnetic resonance imaging represent fundamental tools in the attempt to recognize findings not only suggesting the diagnosis of MMC, but also helping to differentiate between the two his-tological types of the neoplasm directly related to different prognostic factors (11,(13)(14)(15) .…”

Mucinous carcinoma of the breast: iconographic essay with histopathological correlation

et al. 2013

View full text Add to dashboard Cite

The present essay is aimed at describing the most characteristic imaging findings of mucinous carcinoma of the breast, with emphasis on the patterns related to better prognosis. The authors selected cases of mucinous carcinoma of the breast whose images were available, highlighting the imaging findings suggestive of this subtype of breast cancer, either at mammography, ultrasonography or magnetic resonance imaging.

“…In regions such as Eastern Europe, South America, the Southern African region and Western Asia, the reported incidence is moderate, however, it is increasing (1) . Such a fact is followed by a decrease in mortality, which is intimately related to early detection of breast diseases and to the increasing availability of appropriate treatment (2) . In Portugal, the recorded incidence is approximately 4,000 new cases/year (3) .…”

Objective: To compare the capacity of mammography, sonoelastography, B-mode ultrasonography and histological analysis to differentiate benign from malignant breast lesions. Materials and Methods: A total of 12 histopathologically confirmed breast lesions were documented. The lesions were assessed by means of mammography, B-mode ultrasonography and sonoelastography, and histopathological analysis was utilized as a gold standard. Sensitivity and specificity were calculated. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic performance of the mentioned techniques. Results: Sensitivity and specificity in the differentiation between benign and malignant lesions were respectively 100% and 50% for mammography, 100% and 71% for B-mode ultrasonography, and 67% and 83% for sonoelastography. The area under the ROC curve was calculated for the three imaging modalities and corresponded to 0.792 for mammography, 0.847 for B-mode ultrasonography, and 0.806 for sonoelastography. Conclusion: Sonoelastography demonstrated higher specificity and lower sensitivity as compared with mammography and B-mode ultrasonography. On the other hand, B-mode ultrasonography had the largest area under the ROC curve. Sonoelastography has demonstrated to be a promising technique to detect and evaluate breast lesions, and could potentially reduce the number of unnecessary biopsies. Keywords: Breast B-mode ultrasonography; Breast lesions; Mammography; Sensitivity; Specificity; Sonoelastography.Objetivo: Comparar a capacidade de diferenciação de lesões benignas versus malignas por parte da mamografia, ultrassonografia modo-B e elastografia. Materiais e Métodos: Um total de 12 lesões mamárias confirmadas histologicamente foi documentado. A avaliação das lesões foi realizada por meio da mamografia, ultrassonografia modo-B e elastografia. Os resultados histopatológicos foram utilizados como técnica padrão ouro. As sensibilidades e as especificidades foram calculadas. A curva receiver operating characteristic (ROC) foi realizada para avaliar o desempenho diagnóstico das técnicas utilizadas. Resultados: A sensibilidade e a especificidade na diferenciação entre lesões mamárias benignas e malignas foram 100% e 50%, respectivamente, para a mamografia, e 100% e 71% para a ultrassonografia modo-B. A elastografia obteve sensibilidade de 67% e especificidade de 83%. A área abaixo da curva ROC foi calculada para as três técnicas imaginológicas, sendo 0,792 para a mamografia, 0,847 para a ultrassonografia modo-B e 0,806 para a elastografia. Conclusão: A elastografia mostrou ter maior especificidade e menor sensibilidade comparativamente à mamografia e à ultrassonografia modo-B. A ultrassonografia modo-B foi a técnica que demonstrou maior área abaixo da curva ROC. A elastografia mostra-se uma técnica promissora na detecção de doença mamária e, potencialmente, poderá reduzir biópsias desnecessárias. Unitermos: Elastografia; Especificidade; Lesões mamárias; Mamografia; Sensibilidade; US modo-B mamária. Abstract
