对比分析MRI和CT技术对鼻咽癌T分期的影响

The Comparative Analysis of MRI and CT Technology on T Staging of Nasopharyngeal(NPC)

目的对比分析MRI和CT技术对鼻咽癌T分期的影响。方法统计分析2012年3月至2014年3月我院收治的54例鼻咽癌患者的临床资料。结果 MRI技术下的鼻咽癌T分期中T1、T4分期患者例数明显比CT技术多(P<0.05),但二者在T2、T3分期方面的差异均不显著(P>0.05);MRI和CT技术相对应T分期的相同符合率为75.9%(41/54);MRI和CT技术在鼻咽癌T分期口咽、头长肌、海绵窦、椎前间隙、颈静脉孔、斜坡、颈A鞘区部分占据、颈A鞘区完全占据显像率差异均显著(P<0.05),但在其余各部位差异均不显著(P>0.05)。结论在显示鼻咽癌软组织、斜披等特殊部位的结构方面,MRI比CT敏感,能够将准确的依据提供给T分期判断及治疗靶区的确定,具有较高的诊断价值。

Objective To compare and analyze the impact of MRI and CT technology on T staging of NPC.Methods The clinical data of 54 cases of NPC carcinoma patients in our hospital from March 2012 to March 2014 were statistically analyzed.Results The numbers of patients in T1, T4 staging of nasopharyngeal T staging under MRI technology were significantly more than CT technology （P〈0.05）, but the differences between T2, T3 staging areas were not significant （P〉0.05）; The same rate of MRI and CT technology corresponds to T staging was 75.9% （41/54）; The differences of nasopharyngeal T stage oropharynx, head longus, cavernous sinus, anterior gap, the jugular foramen, the slope neck A sheath section occupied neck A sheath completely occupied imaging rate between MRI and CT technology were significant （P〈0.05）, but the differences in the rest of the parts were not significantly （P〉0.05）.Conclusion MRI is more sensitive than CT in structure display of special parts nasopharyngeal soft tissue, such as oblique Phi, it can provide an accurate basis for T staging judgement and treatment planning determination, has higher diagnostic value.
