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

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(P0.05), but the differences between T2, T3 staging areas were not significant(P0.05); 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(P0.05), but the differences in the rest of the parts were not significantly(P0.05). 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.
