Abstract |
Objective 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).
Materials and 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.
Conclusion 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. |
