Journal of Neuroimaging<\/a><\/em>, publicaci\u00f3 oficial de la Societat Americana de Neuroimatge.<\/p>\nLa preservaci\u00f3 de l\u2019\u00e0rea del llenguatge durant la cirurgia \u00e9s un factor essencial per evitar d\u00e8ficits neurol\u00f2gics permanents i t\u00e9 un impacte important en la qualitat de vida del pacient despr\u00e9s de la intervenci\u00f3 quir\u00fargica.<\/p>\n
En aquest estudi, els investigadors han utilitzat la resson\u00e0ncia magn\u00e8tica i, m\u00e9s en concret, la t\u00e8cnica coneguda com a \u201ctensor de difusi\u00f3\u201d per precisar millor com el grau tumoral i la localitzaci\u00f3 del tumor influeixen en les \u00e0rees del llenguatge. Espec\u00edficament, l\u2019an\u00e0lisi s\u2019ha centrat en l\u2019estudi d\u2019una \u00e0rea del cervell, el fascicle front-occipital inferior en el seu recorregut a trav\u00e9s del l\u00f2bul temporal, que juga un paper fonamental en la sem\u00e0ntica i en el processament ortogr\u00e0fic del llenguatge.<\/p>\n
L\u2019afectaci\u00f3 d\u2019aquest fascicle front-occipital inferior pot fer que el pacient deformi o substitueixi paraules durant el discurs. Segons destaca la Dra. \u00c0ngels Camins<\/strong>, gr\u00e0cies a la informaci\u00f3 aportada per aquest treball \u201cels cirurgians podran identificar de forma sistematitzada i no invasiva aquest fascicle, ajudant a definir amb precisi\u00f3 els l\u00edmits de la resecci\u00f3 tumoral<\/em>\u201d.<\/p>\nLa resson\u00e0ncia magn\u00e8tica funcional permet detectar de manera no invasiva els canvis fisiol\u00f2gics que tenen lloc al cervell relacionats amb processos mentals, per exemple durant l\u2019execuci\u00f3 d\u2019una tasca. Les imatges de la resson\u00e0ncia s\u2019obtenen aprofitant determinades propietats magn\u00e8tiques de la mat\u00e8ria i es basen en la premissa que, en produir-se un proc\u00e9s mental, les neurones involucrades requereixen d\u2019una major quantitat d\u2019energia.<\/p>\n
En aquest tipus d\u2019estudis, s\u2019obtenen les imatges alhora que el pacient executa una tasca especifica del llenguatge i s\u2019identifica aix\u00ed en quin lloc exacte del seu c\u00f2rtex cerebral es produeix aquesta activitat. Aquestes imatges es complementen amb les del tensor de difusi\u00f3, que proporciona informaci\u00f3 sobre les fibres o tractes cerebrals que connecten les \u00e0rees corticals obtingudes a la resson\u00e0ncia magn\u00e8tica funcional.<\/p>\n
El Dr. Andreu Gabarr\u00f3s<\/strong>, cap del Servei de Neurocirurgia de l\u2019Hospital de Bellvitge i l’IDIBELL i coautor de l\u2019estudi, destaca que \u201ca banda de la seva utilitat en la recerca i les neuroci\u00e8ncies cognitives, la resson\u00e0ncia magn\u00e8tica funcional s\u2019ha convertit en la pr\u00e0ctica cl\u00ednica en una eina fonamental per tal d\u2019identificar funcions neurol\u00f2giques concretes i poder establir aix\u00ed la millor traject\u00f2ria quir\u00fargica per preservar aquestes funcions<\/em>\u201d.<\/p>\n <\/p>\n
