摘要
[目的]探讨磁共振(MRI)对鼻咽癌颅底骨侵犯的诊断价值。[方法]分析2003年7月至2004年12月35例颅底骨质破坏初诊鼻咽癌患者放疗前后MRI的变化。[结果]35例鼻咽癌患者放疗前均存在程度不等的颅底骨质破坏,MRI可见T1WI骨髓高信号消失及压脂增强后明显强化。经放射治疗,35例患者均呈放疗后状态。[结论]MR平扫及增强扫描图像对鼻咽癌TNM分期及疗效判断有重要价值。
[Purpose] To evaluate the diagnostic value of magetic resonance imaging （MRI） in detecting skull base involved nasopharyngeal carcinoma （NPC）. [Methods] Manifestation changes of MRI in 35 cases of NPC with skulll base involvement from July 2003 to December 2004 were analyzed before and after radiotherapy. [Result] NPC with certain skull base involvement was found in all 35 cases before radiotherapy. The loss of high signal of bone marrow （T1WI） and obviously enhancement after fat pressed enhancement could be seen in all 35 cases. All 35 cases showed postradiotherapeutic condition after radiotheraphy. [Conclusion] Plain scan and enhancement scan of MRI play an important value in TNM staging and response evaluation.
