Abstract:
Objective To evaluate the reliability and accuracy of three-dimensional digital fusion anatomy in the preoperative evaluation and therapeutic strategy choice of intracranial tumors.Methods MRI scan,including regular MRI,MRA,MRV and DTI,were performed in 87 case.Then tumor themselves as well as tumor-associated structures were reconstructed and fused through iPlan 2.6 software.Based on the reconstructed images,therapeutic strategy were established,preoperative and intraoperative imags were compared.Results The digital reconstruction were successfully finished in all cases.Meanwhile,digital images,originally radiological images and actual images matched well.No approach-associated complication were met in our series.Among tumors in the convexity,the relationship of the reflux veins and the tumors were divided into three types:anterior(12 cases),posterior(19 cases) and overriding(3 cases).All of the relationships were seen in the preoperative fusion image,and the veins were all effectively protected during operation.The tumor-associated arteries could be pushed or wraped by the tumors,and the three-dimensional fusion image could provided their virtually aberrant pathway as well as their relationship with tumor.During microsurgical managment of tumors in the deep brain parenchyma,safe approach were found with the help of comprehensive understanding of the tumors and their adjacent structures.Conclusion Three-dimensional digital fusion anatomy can vividly and accurately display full rang of information about the tumor,and facilitate tumor treatment safely.
