As imagens de ressonância magnética ponderadas por difusão retratam a difusividade de moléculas de água presentes em tecidos biológicos. Em estruturas biológicas altamente organizadas e compactas como fibras nervosas e musculares, a difusividade é maior na direção paralela às fibras do que perpendicularmente às mesmas. Essa propriedade permite a reconstrução digital das trajetórias das fibras, técnica denominada tractografia, representando uma das poucas formas não invasivas de investigação da conectividade anatômica e organização estrutural do cérebro e do coração. A metodologia de tractografia mais difundida faz uso da integração numérica da direção principal de difusividade para reconstruir essas trajetórias. Porém, esta técnica apresen...
