Open Spina Bifida Aperta Atlas

The Open Spina Bifida Aperta (OSBA) atlas is a set of neuroimaging templates for newborns with open spina bifida (spina bifida aperta, SBA). The OSBA atlas was constructed using structural T2-weighted and diffusion tensor MRI of 28 newborns with SBA. The corrected gestational age at MRI was 38.1 ± 1.1 weeks (mean ± SD). The OSBA atlas consists of T2-weighted and fractional anisotropy templates, along with 9 tissue prior maps and region of interest (ROI) delineations. The OSBA atlas offers a standardized reference space for spatial normalization and anatomical ROI definition.
