Abstract:
Objective To compare the results of CT/MRI registration by using two different marker materials. Methods CT and MR transversal images (using electric wire and thin tube filled with lohexol injection as matching points respectively) were obtained from nine cases with brain tumor. Another CT and MR transversal images were also obtained by using the cod-liver oil capsule filled with gadopentetate dimeglumine injection as matching points with the same scanning position. The images were transferred to the TPS for image registration and the effect was evaluated. Results The CT/MRI CRE range for using different kinds of marker material was 0.16-0.28cm,while was 0.06-0.16cm for using the same marker material. Conclusion Comparing with the method using different kinds of material,the method using the same spherical material can get better results in CT/MRI registration.
