Abstract Objective: To investigate the diagnostic value of diffusion kurtosis imaging(DKI) in head and neck lymphoma. Methods: The clinical data of 114 cases of head and neck lymphoma(neck lymphoma group), 97 tumor patients with neck lymph node metastasis(lymph node metastasis group) and 82 healthy individuals with benign lymph nodes(benign lymph node group) diagnosed by biopsy from January 2016 to January 2019 in our hospital were retrospectively analyzed. All the selected subjects underwent the DKI examinations. Diffusion(D) and kurtosis(K) values were recorded, and were compared among head and neck lymphoma patients with different pathological types and cell sources. ROC curve was used to analyze the value of DKI in the diagnosis of head and neck lymphoma. Results: There was significant difference in D value among the three groups(F=96.380, P<0.05). D value of head and neck lymphoma group was significantly lower than that of lymph node metastasis group and benign lymph node group(P<0.05). D value of Non-Hodgkin’s lymphoma(NHL) type was significantly lower than that of Hodgkin’s lymphoma(HL) type(P<0.05). D and K values of NHL from B cells and T cells had no significant difference(P>0.05). When the D value was 1.06×10-3 mm2/s, the AUC, sensitivity and specificity of D value in the diagnosis of head and neck lymphoma was 0.801, 85.09% and 69.83%, respectively. When the D value was 0.94×10-3 mm2/s, the AUC, sensitivity and specificity of D value in the diagnosis of head and neck lymphoma was 0.817, 68.18% and 89.13%, respectively. Conclusion: The D value of magnetic resonance DKI has a high value in the diagnosis and classification of head and neck lymphoma, which can provide a reliable basis for early diagnosis of head and neck lymphoma.
