鼻咽癌CT与MRI诊断结果对比及临床价值

Results of CT and MRI Diagnosis and Clinical Value of Nasopharyngeal Carcinoma （NPC）

目的：对鼻咽癌向周围一些临近的结构出现侵犯之后在 CT以及MRI中的表现和诊断结果进行对比和分析，希望能够对问题的及时发现和决策的制定提供一定的科学依据。方法：通过对经过病理证实的20例鼻咽癌患者的CT和MRI的资料进行分析和对比，对CT以及MRI对于鼻咽癌的诊断结果进行了分析。结果：在20例鼻咽癌患者中，T1WI等信号有13例（65．0％），T2WI高信号有17例（85．0％）。 CT同MRI对于鼻咽癌以下结构浸润率的显示具有明显的差异，其中完全茎突后间隙以及海绵窦的P值分别为0．014、0．016。对于副鼻窦的检出效率方面两者的差异没有统计学意义。结论：采用MRI来对鼻咽癌患者进行影像学的检查可以取得良好的诊断结果。此外，MRI还可以对肿瘤的侵犯范围进行更加准确的了解，因此已经成为了临床上检查鼻咽癌的首选影像学方式。

Objective：Nasopharyngeal carcinoma into the surrounding some to neighboring structure appeared after the assault on the performance of CT and MRI , and compare the results of diagnosis and analysis of the problems found in time and to provide certain scien -tific basis for decision making .Methods：through the after 20 cases of pathologically proven of CT and MRI in patients with nasopharynge -al carcinoma （ NPC） data analysis and comparison , the result of the CT and MRI for the diagnosis of nasopharyngeal carcinoma were ana -lyzed.Results：In 20 patients with nasopharyngeal carcinoma , such as T1WI signal in 13 cases （65.0%）, high T2WI signal in 17 cases （85.0%）.CT and MRI in nasopharyngeal carcinoma following structure of infiltration rate show significant differences , which fully sty-loid process after clearance and cavernous sinus P values were 0.014, 0.016, respectively.For detection of paranasal sinus efficiency difference of no statistical significance .Conclusion：Using magnetic resonance imaging （ MRI） for nasopharyngeal carcinoma patients with the diagnosis of imaging examination can achieve good results .In addition, MRI can also to more accurate understanding of the scope of tumor invasion, thus has become a clinical examination imaging method of choice for nasopharyngeal carcinoma （NPC）.
