Primary study on diffusion tensor tracking in assessing of prognosis of neurofunction recovery for patients with hypertensive intracerebral hemorrhage

Objective:To study the impairment severity of cortical spinal tract(CST) of 18 cases with hypertensive intracerebral hemorrhage(HICH) in basal ganglion region by using diffusion tensor tracking(DTT),and to evaluate the clinical value of DTT in assessing the recovery and prognosis of HICH.Method:Eighteen patients with HICH in basal ganglion region were performed duffusion tensor imaging(DTI) using GE sina exite imaging system.American national institutes of health stroke assessment(NIHSS) scores were used for assessment of nerve function injury and the muscle strength were assessed at admission,and the 3rd month,the 6th month after attack of HICH.The relationship between the impairment severity of CST and the level of nerve function in various periods was analyzed.Result:The CST of healthy side showed on DTT was well consistent with known anatomic features,however the CST of affected side was compressed,displaced and broken.The recovery of muscle strength and NIHSS score of patients with intact CST at different periods were better than those in patients with interrupted CST.Three months after attack was the fastest stage of neurological function recovery.Conclusion:For patients with HICH in basal ganglion region,the impairment severity of CST could be evaluated by using DTI,and it was helpful for clinicians to judge the recovery and prognosis of neurological function and to formulate the treatment scheme.
