X-knife Treatment of Intracranial Lesions:CT Iocalization

Objective:To explore the methord of CT localization for X-knife treatment of intracranial lesions.Methods:337 cases of intracranial tumors and arteriovenous malformations were treated by X-knife with CT aided lacalization.A FN-89 or Fischer stereotactic frame combine with Somatom-DR CT system was used for CT scan.According to the CT image series the X-knife treatment plan was quickly optimized with the software of stereotactic treatment planning(STP).Results:With CT scan all the lesions were located accurately in X-knife treatment.Conclusion:We conclude that X-knife using CT located is an effective and safe technique in the treatment of intracranial tumors and AVMs.
