Abstract：Objective To study the diffusion changes in basilar part of pons after striatocapsular infarction with diffusion tensor imaging ,and to explore its relationship with upper limb motor functional lesion .Methods 15 patients with unilat-eral upper limb motor functional lesion after striatocapsular infarction onset at first time were enrolled and performed with DTI scan 2 weeks after onset .We measured the fractional anisotropy (FA) and the mean diffusivity (MD) of amphi-basi-lar part of pons and computerized the asymmetry index (AI) of FA of two sides .Correlation analysis was performed with AI and FM scores of the affected upper limb .Results The FA of affected side basilar part of pons decreased significantly compared with the unaffected side and the MD of two sides were resemblance at 2 weeks after onset .There was significant negative correlation between AI and FM scores of the affected upper limb .Conclusion DTI can detect early diffusion changes in basilar part of pons after striatocapsular infarction .The integrity of pyramidal tract in basilar part of pons and the motor function of affected upper limb are closely related .DTI can provide considerable reference index for clinical as-sessment on striatocapsular infarction .
