Background Diffuse midline gliomas (DMG) are characterized by a high incidence of H3 K27 mutations and poorer outcome. The HERBY trial has provided one the largest cohorts pediatric DMGs with available radiologic, histologic-genotypic, survival data. Purpose To define MRI molecular characteristics DMG. Materials Methods This study is secondary analysis prospective (HERBY; ClinicalTrials.gov identifier, NCT01390948) undertaken between October 2011 February 2016. Among 121 participants, 50 had...

With the rapidly increasing development of telemedicine technology, evaluation telemedical services becomes more and important. However, professional views aims methods are different from perspective computer science engineering or medicine health policy. We propose that a continuous strategy should be chosen which guides implementation technologies applications. The is divided into four phases in focus shifted technical performance system early to medical outcome criteria economical aspects...

Determination of tumor response to treatment in neuro-oncology is challenging, particularly when antiangiogenic agents are considered. Nontumoral factors (eg, blood-brain barrier disruption, edema, and necrosis) can alter contrast enhancement independent true response/progression. Furthermore, gliomas often infiltrative, with nonenhancing components. In adults, the Response Assessment Neuro-Oncology (RANO) criteria attempted address these issues. No such guidelines exist yet for children....
