Abstract(s)
A Ressonância Magnética (RM) multiparamétrica
é essencial na avaliação das lesões anexiais
indeterminadas em ecografia, pois possibilita
a adequada caracterização destas lesões,
classificando-as consoante o grau de suspeita de
malignidade. Permite também, orientar a correta
abordagem terapêutica e/ou de seguimento,
limitando os custos associados.
A maioria das lesões anexiais ecograficamente
indeterminadas são de natureza benigna, e
a sua caracterização por RM evita cirurgias
desnecessárias e inapropriadas. Apenas uma
minoria destas lesões corresponde a doença
anexial maligna, e a sua adequada avaliação por
RM permite a implementação atempada da
correta abordagem terapêutica, aspecto essencial
na conduta destes tumores.
Neste artigo as autoras revêm e ilustram as
características em RM das lesões anexiais
indeterminadas em ecografia, permitindo
classificá-las segundo o seu grau de suspeição.
É ainda, realçado o protocolo de RM
multiparamétrica que deve ser aplicado no estudo
destes tumores.
Multiparametric magnetic resonance imaging (MRI) is essential in the evaluation of sonographically indeterminate adnexal lesions, because it enables an adequate characterization of these lesions and their classification based on the degree of suspicion for malignancy. It also allows the most accurate therapy and/or follow-up approach, limiting the associated costs. The majority of indeterminate adnexal lesions at ultrasound are benign and its characterization with MRI avoids unnecessary and inappropriate surgery. Only a minority of these lesions corresponds to malignant adnexal disease, and their proper evaluation by MRI allows timely implementation of the correct therapeutic approach, which is the key aspect in the management of these tumors. In this article the authors review and illustrate the MRI characteristics of the sonographically indeterminate adnexal lesions, which classifies them attending to their degree of suspicion. The multiparametric MRI protocol that should be applied in the study of these tumors is also highlighted.
