| 目的 探讨MRI对鼻咽癌(NPC)的UICC/AJCC(2002,6th)分期和我国1992年福州分期的影响。方法 分析经病理证实的39例NPC患者的影像学资料,治疗前1周内均有CT和MRI资料。结果 CT不能显示咽颅底筋膜,MRI显示清楚;MRI显示茎突后间隙肿块和鼻窦肿块性质较CT明确;MRI显示颅底骨质肿瘤侵犯较CT敏感。根据UICC/AJCC分期标准,28.2%(11/39)的病例发生分期改变,根据1992年福州分期标准,35.9%(14/39)发生改变。结论 MRI对于鼻咽癌的侵犯途径和范围,特别早期诊断有重要意义。建议NPC临床分期应考虑以MRI为标准。 |

| Objective To investigate the influence of MRI on the T, N staging system, 6th edition, UICC/AJCC and the 1992 Fuzhou staging system, China, by comparing CT and MRI of nasopharyngeal carcinoma (NPC). Methods Thirty-nine cases pathologically proven as nasopharyngeal carcinoma were selected from March 2003 to September 2004. All were underwent CT and MRI examination in one week before treatment. Results The pharyngobasilar fascia could be seen by MRI which not by CT. MRI appeared more superiority than CT in the composing of retrostyloid space and paranasal sinuses invasion by tumor tissue of NPC. MRI was more accurate than CT in destruction the base of skull. As a result, 28.2% (11/39) of NPC staging system, UICC/AJCC and 35.9% (14/39) of the 1992 Fuzhou staging system of China were should undergo changes. Conclusion MRI is beneficial to scanning the range, passage and extent of NPC, especially in the preliminary diagnosis of NPC. MRI was considered to be the standard imaging exam for clinical stage of NPC. |
