Purpose
The most common etiology for patients with cerebral palsy (CP) was white matter injury by cerebral ischemia in preterm or term infants. In this cross-sectional study, we used fixel-based analysis (FBA) to investigate white matter differences between patients with CP and typical developing (TD) children.

Materials and Methods
From 2011 to 2013, a total of 34 children with CP (Compatible with periventricular leukomalacia, 19 boys and 15 girls; mean age: 11.5±3.2 years), and 27 sex-balanced TD children (14 boys and 13 girls; mean age: 17.5±3.6 years) were recruited. Diffusion-weighted images were obtained using a 3T MR scanner. Fiber density (FD) and fiber bundle cross-section (FC), the fixel-specific measures, were calculated within each voxel. A Combined measure (termed FDC) was derived by multiplying FD and FC. An FWE-corrected p < 0.05 with a cluster-extent-based threshold of 10 or more voxels was considered statistically significant.

Results
Compared to the TD children, children with CP reduced in FC and FDC in the anterior and posterior part of the corpus callosum, posterior limb of internal capsule,
superior and posterior thalamic radiation, cingulum fiber, optic radiation, and superior longitudinal fasciculus. In contrast, FD reductions were identified in the posterior part of the corpus callosum, posterior thalamic radiation, fornix, and cingulum fiber. Conclusion
This study provides a thorough FBA profile of white matter differences in patients with CP and TD children with new evidence of FD, FC, and FDC, which helped to clarify the influence of disease on the development of specific white matter regions.
