Abstract Objective Compare the application effects of 3.0T MR 3D T1-SPACE enhancement and T1 TSE DIXON enhancement sequences in nasopharyngeal carcinoma(NPC)scanning.Methods 105 patients diagnosed with nasopharyngeal carcinoma in our hospital between January 2022 and March 2025 were selected and underwent 3.0T MR 3D T1-SPACE enhancement and T1 TSE DIXON enhancement sequence examinations.The artifacts and tumor display effects,detection of primary lesion invasion range,and cervical lymph node metastasis examination were compared between the two examination methods.Results The artifact and tumor display effect scores of the 3D T1-SPACE enhancement sequence were points and points,respectively,which were higher than those of the T1 TSE DIXON enhancement sequence points and points(P<0.05).Compared with the T1 TSE DIXON enhancement sequence,the detection rates of NPC invasion into the cavernous sinus,intracranial,sinus,skull base bone,retropharyngeal lymph nodes,oropharynx,and parapharyngeal space in the 3D T1-SPACE enhancement sequence were,and,respectively,which were higher than those in the T1 TSE DIXON enhancement sequence respectively(P<0.05).The detection rates of cervical lymph node metastasis in Zone II and Zone III using 3D T1-SPACE enhancement sequence were respectively,which were higher than those ofusing T1 TSE DIXON enhancement sequence(P<0.05).Conclusion The application of T1 TSE DIXON enhancement sequence and 3D T1-SPACE enhancement sequence in NPC scanning can provide more satisfactory image quality,and the detection rate of primary lesion invasion range is higher,with a higher detection rate of cervical lymph node metastasis in Zone II and Zone III.
