Myxoid chondrosarcoma of the sinonasal cavity in a child: a case report.

abstract：OBJECTIVE:Many studies have reported pre-processing effects for brain volumetry; however, no study has investigated whether non-parametric non-uniform intensity normalization (N3) correction processing results in reduced system dependency when using an atlas-based method. To address this shortcoming, the present study ...
