Abstract: Objective To explore the establishment and significance of image fusion of MRI and CT scans in laryngeal carcinoma. Methods Conventional body frame and thermoplastic mask were improved and its set-up error were compared with the old one. Thirty one laryngeal carcinoma patients underwent MRI and CT scan with same protocol in the same body position. The two images were transferred into Pinnacle3 V8.0 for registration and fusion. Images of CT, MRI and the fusion were evaluated subjectively. Results Quality of fused images from the 23 patients were satisfying. The result of fusion could be displayed in three ways, including Alpha Blending, Checkerboard and Target Region. In these fused images, both cartilages and soft tissue lesions could be clearly displayed. Conclusion Image fusion of MRI and CT scans in the patients with laryngeal carcinoma can correct the disadvantages of CT scan by improving the visualizaion of soft tissue lesions in the throat, to facilitate the evaluation of the tumor infiltration.

Key words: Image fusion, X-ray computer tomography, Magnetic resonance image, Laryngeal neoplasm
