| 摘 要： | 目的 探索喉部CT/MRI融合图像的建立方法及意义。方法 改良头颈肩固定体膜体架并比较其与常规装置的重复摆位误差；31例喉癌患者应用同一装置固定体位，1 d内先后行CT和MRI扫描，层厚3 mm，将数据导入飞利浦公司Pinnacle3 V8.0放射治疗计划系统进行自动配准和融合。对融合图像、MRI、CT图像进行主观评价。结果 23例（23/31）CT/MRI融合图像清晰；融合后的数据可以透明混合、棋盘格式、靶区勾画多重显示三种方式观察；既能够清晰显示甲状软骨、环状软骨、杓状软骨，又可以显示会厌、 声带、室带、喉室、会厌前间隙、声门旁间隙、杓会厌皱襞、喉软骨破坏、喉外组织等喉部结构病变及喉癌的颈淋巴结转移。结论 喉部CT/MRI融合图像，可以弥补CT在喉部软组织病变的显示不清晰的缺点，对喉癌手术前肿瘤范围的评估具有重要意义。

| 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. |
