ABSTRACT
Summary

Objective:

the aim of this study was to investigate the addition of elastography to the BI-RADS® lexicon for the classification of breast lesions.

Methods:

a total of 955 consecutive patients who were subjected to breast percutaneous biopsy from January 2010 to December 2012 were retrospectively assessed. Overall, 26 patients who did not present with masses on conventional ultrasound were excluded. The patients were classified according to the fifth edition of the breast imaging and reporting data system (BI-RADS®) lexicon, which includes elastographic findings. The BI-RADS®classification is based on the same classification principles that have been suggested by the author, which classify lesions as soft, intermediate, or hard.

Results:

the addition of elastographic findings to the BI-RADS® lexicon improved the sensitivity (S), specificity (SP), and diagnostic accuracy (DA) of ultrasound in the assessment of breast lesions, which increased from 93.85, 72.07, and 76.64 to 95.90, 80.65, and 91.39%, respectively.

Conclusion:

these findings suggest that the addition of elastography to the BIRADS ® lexicon will improve the SP and DA of ultrasound in the screening of breast lesions.
RESUMO
Resumo

Objetivo:

investigar o impacto da adição da descoberta da elastografia das lesões mamárias à classificação segundo o léxico BI-RADS®.

Métodos:

estudo retrospectivo com 955 pacientes consecutivas, submetidas à biópsia mamária percutânea no período de janeiro de 2010 a dezembro de 2012. Foram excluídas 26 pacientes que apresentaram lesão não nodular ao ultrassom convencional. As lesões foram classificadas conforme proposta da 5ª edição do léxico BI-RADS®, que inclui os achados de elastografia. A classificação BI- -RADS® é baseada nos mesmos critérios propostos pelo autor, que classifica as lesões como macias, intermediárias e rígidas.

Resultados:

a adição dos achados da elastografia ao léxico BI-RADS® melhorou a sensibilidade (S), a especificidade (E) e a acurácia diagnóstica (AD) do ultrassom na avaliação das lesões mamárias, de 93.85, 72.07 e 76.64% para 95.90, 80.65 e 91.39%, respectivamente.

Conclusão:

os achados sugerem que a adição dos achados da elastografia ao léxico BI-RADS® pode melhorar a S, a E e a AD do ultrassom no rastreamento de lesões mamárias.
