Researchers at the Children’s Hospital Los Angeles have recently discovered a new imaging technique to help classify pediatric brain tumors noninvasively. Using magnetic resonance spectroscopy (MRS), investigators were able to identify four different subtypes of medulloblastoma (SHH, WNT, Group 3 and Group 4). The current practice of subgroup determination is completed after removing the tumor surgically. “The ease of obtaining MRS at the time of diagnosis should allow its incorporation into future clinical trials aimed at validating this technique to improve diagnostic classification and, ultimately, improve outcomes in children with medulloblastoma.”
