Abstract:
Objective To investigate PET/CT and PET/MR characteristics of head and neck squamous cell carcinoma (HNSCC).Methods Totally 40 patients with HNSCC underwent whole body 18F-FDG PET/CT and MR scans of head and neck before anti-tumor treatment.PET positive lesions of HNSCC,including primary lesions and lymph nodes were evaluated by 2 radiologists independently.Then the imaging quality,fusion quality,lesion conspicuity and lesion characteristics were assessed based on PET/CT,PET/MR T1WI and PET/MR T2WI.Results Ninety PET positive lesions in all 40patients were evaluated,including 40 primary lesions and 50 lymph nodes.Similar imaging quality and fusion quality of PET/CT,PET/MR T1WI and PET/MR T2WI were obtained without statistical difference (both P＞0.05).For the lesion conspicuity,PET/MR T1WI and PET/MR T2WI demonstrated significantly better than PET/CT in positive primary lesions and lymph nodes (all P＜0.05).For the characteristics of positive primary lesions,PET/MR T2WI provided more information than PET/CT in 29 lesions,equal to PET/CT in 4 lesions,and less than PET/CT in 7 lesions.Conclusion The application of PET/MR in HNSCC is feasible,being superior to PET/CT in indication of lesions in head and neck area.
