OBJECTIVE: To investigate the value of multi-ultrahigh-b-value diffusion-weighted imaging (UHBV-DWI) in differentiating high-grade astrocytomas (HGAs) from low-grade astrocytomas (LGAs), analyze its association with aquaporin (AQP) expression. METHOD

Avaliou-se a relação colina/N-acetil-aspartato (Co/NAA), obtida pela espectroscopia multivoxel com tempo de eco (TE) curto, na graduação histológica dos astrocitomas encefálicos (graus I, II e III-IV), comparando com o parênquima cerebral norm

Publikováno v: Cancer. 66:6-14

Of 77 patients with supratentorial Grades I and II astrocytoma diagnosed from January 1975 to December 1984, 66 were treated with postoperative radiation therapy. The patients received a tumor dose of 5000 to 5500 cGy in 180 cGy fractions, five fract
