Abstract

Objective: The aim of this study was to evaluate the benefit of image fusion of CT (computertomography) and bone SPECT (single photon emission computed tomography) in diagnosis of head and neck cancer.

Methods and patients: Computer based image fusion has been applied in 39 patients with suspected cancer in the oromaxillofacial region following CT and SPECT without any further hazard for the patients. Afterwards image fusion was set in comparision to simultaneously evaluation of CT and SPECT and histological findings.

Results: In 5 out of 39 patients SPECT/CT image fusion obtained more precise anatomical findings in tumour expansion than simultaneously evaluation of CT and SPECT.

Conclusion: For planning of surgical and radiation therapy of oral and maxillofacial cancer, image fusion of CT/SPECT provides efficient and plastical diagnostic imaging. Particularly in complex anatomical regions like maxilla or base of the skull image fusion could be an additional device, if simultaneous evaluation of CT and SPECT is not clear.

[骨SPECT与CT图像融合——口腔颌面外科的一种特殊诊断方法]。

目的:评价CT(计算机断层扫描)和骨SPECT(单光子发射计算机断层扫描)图像融合在头颈部肿瘤诊断中的价值。方法与患者:对39例口腔颌面部疑似肿瘤的CT及SPECT影像进行融合处理，对患者无进一步危害。之后将图像融合与CT、SPECT的同时评价及组织学表现进行比较。结果:39例患者中有5例SPECT/CT图像融合在肿瘤扩张中获得了比CT和SPECT同时评估更精确的解剖表现。结论:CT/SPECT影像融合可为口腔颌面部肿瘤的手术及放疗规划提供高效、可塑的诊断影像。特别是在复杂的解剖区域，如上颌骨或颅底，如果CT和SPECT的同时评估不清楚，图像融合可以是一个额外的设备。
