iPath 200 interventional MRI-guided nerve root infiltration
Abstract：Objective:To describe the procedure and evaluate the accuracy of the interventional MRI guided nerve root infiltration.Methods:13 patients with intervertebral disk herniation underwent interventional MRI-guided nerve root infiltration.4 cases of cervical and 9 cases of lumbar nerve roots were infiltration.All patients were performed under 0.23 T open MRI system (Proview,Philips Medical System) with optical tracking system (iPath 200,Philips Medical System).The needle was MR-compatible (Daum, Germany, 20G). The outcome was evaluated as effect on radiculalgia 1～2 months (mean 1.2 months) after the procedure by clinical examination.The effect on radiculalgia was graded as follows:① Obvious relief=the pain obvious or complete relief at the time of outcome evaluation.② Temporary relief=temporary relief of pain.③ No relief but no worsening of pain.④ Worsening of pain.Results:The rate of obvious relief was 92.3% (12/13).The rate of temporary relief was 7.7% (1/13).No patient was no relief of pain or worsening.Conclusion:IMRI-guided nerve root infiltration is an accurate and safe technique.
