Abstract:
Objective To study the application of fusion of CT and MRI images in X-knife treatment for intracranial lesions.Methods Total 25 patients included:3 gliomas,3 acoustic neuroma,2 pituitary adenoma,one craniopharygioma to be remained or recurred postoperatily,2 pituitary micro-adenoma,5 AVM,4 cavernous angioma,3 metastatic tumour,one neoplasm located pituitary stem and midbrain respectively.Before the fusion of CT and MRI images MRI scan and CT scan for location of X-knife were performed respectively,then MR and CT image were transferred to workstation for the fusion of images.Results All lesions were showed clearly on fusional images and more nodules were observed in 3 metastatic tumour.Skull,soft tissue constructures and the profile of lesions were completely overlaped on overlaped images of CT and MR with an error less 1.0 mm.Conclusion CT and MRI images of head can be accurately registered.The images can show the radiologic informations more clearly than conventional CT image.It provides a safe,effective and little harmful method for X-knife treatment of intracranial lesions.
