Introduction: : In injury of the corona radiata of intracerebral hemorrhage (ICH), motor impairment and improvement can be predicted. This study was conducted for comparison of fractional anisotropy (FA) of the corona radiata depending on volume of ICH using diffusion tensor imaging (DTI).

Methods: Twelve patients with cerebral hemorrhage located around the corona radiata in the brain underwent DTI within 6 months of onset. The FA of the corona radiata located in the posterior internal capsule was calculated and compared depending on intracerebral volumes. FA was compared between healthy and unhealthy side and motor improvements were analyzed. FA ratio was compared between Group 1 (Group1, volume of ICH<30ml) and Group 2 (Group 2, volume of ICH=30ml).

Results: Lower FA was found in Group 2 than in Group 1. Negative correlation was observed between FA ratio and volume of hematoma. Motor function also showed good correlation with FA anisotropy of corona radiata located in the posterior internal capsule.

Conclusions: Large ICH has a lower FA ratio. Negative correlation was observed between FA ratio and volume of hematoma. The FA of the corona radiata located in the posterior internal capsule showed good correlation with motor function and ICH volume.

Patient Care: The FA of the corona radiata located in the posterior internal capsule showed good correlation with motor function and ICH.

Learning Objectives: Volumetric comparison of fractional anisotropy using diffusion tensor imaging for corona radiata in patients with intracerebral hemorrhage
