Uso do tensor de difusão na avaliação dos padrões de acometimento da substância branca em pacientes com tumores cerebrais: é uma ferramenta útil para o diagnóstico diferencial?

Abstract: OBJETIVO: Propõe-se avaliar o papel do tensor de difusão na avaliação dos diferentes padrões de acometimento da substância branca em pacientes com tumores cerebrais e a utilidade desta técnica no diagnóstico diferencial dessas neoplasias. MATERIAIS E MÉTODOS: Quarenta e quatro pacientes com tumores cerebrais, incluindo gliomas de baixo grau, astrocitomas anaplásicos, glioblastomas multiformes e metástases, foram estudados com imagens de ressonância magnética convencional e tensor de difusão. Os tratos de subst… Show more

“…A study developed by Itagiba et al on the role of diffusion tensor MRI in the assessment of white matter involvement in 44 patients with brain tumors, have demonstrated four patterns of involvement, namely, edematous, displaced, infiltrated and disrupted. In such series, the edematous and displaced patterns were found in patients with metastasis, but the second one is nonspecific for such a condition (9) . As regards primary neoplasms, the assessment of the peritumoral region is quite useful in the differentiation with metastases (10) .…”

“…Following these brain templates and the raising necessity to others MR imaging modalities, the Diffusion Tensor Imaging (DTI) was also intensively studied to add more possibilities for the white matter brain studies (Alves et al, 2012;Itagiba et al, 2010;Miraldi et al, 2013;Rittner et al, 2014). In the past, the lack of white matter information is understandable due to a homogeneous appearance in conventional MRI, as well as in histology preparations Mori et al, 2008).…”
