We have described the detailed anatomy of the plantar aponeurosis with emphasis on the more distal structures that can be visualized with MRI. There was no statistically significant difference between the accuracy of ultrasonography and MRI regarding the measurements of the thickness of the central and lateral portions of the plantar aponeurosis. Knowledge of the normal anatomy of these structures enables the radiologist to identify early alterations, providing timely diagnosis and treatment.
ResumoA evolução na avaliação por imagens dos sarcomas musculoesqueléticos contribuiu para melhora significativa no prognóstico e na sobrevida dos portadores destas neoplasias. A caracterização precisa destas lesões, mediante utilização das modalidades de imagem mais adequadas a cada condição clínica apresentada, é de suma importância no delineamento da abordagem terapêutica a ser instituída, com impacto direto sobre os desfechos clínicos. O presente artigo busca atualizar o leitor a propósito das metodologias de imagem no contexto da avaliação local e sistêmica dos sarcomas ósseos e das partes moles.
We analyzed the normal osseous anatomy of the metacarpal heads. Knowledge of this normal anatomy enables the radiologist to differentiate normal concave regions from bone erosions that accompany a variety of synovial inflammatory diseases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
