【摘要】：目的:探讨常规MRI联合最小ADC值鉴别诊断颈部转移性淋巴结与淋巴瘤的价值。方法:回顾性分析经病理组织学证实的10例(26个病灶)颈部淋巴瘤和18例(34个病灶)转移性淋巴结患者的MRI图像特点,同时测量并比较颈部淋巴瘤与转移性淋巴结的最小ADC值。结果:颈部淋巴瘤组囊变发生率(8%)低于转移性淋巴结组(53%,P0.05);淋巴瘤组病灶周围渗出发生率(27%)低于转移性淋巴结(38%,P0.05)。淋巴瘤组最小ADC值低于转移性淋巴结组最小ADC值,分别为(0.58±0.12)×10~(-3)mm~2/s、(0.76±0.16)×10~(-3)mm~2/s,两者间差异有统计学意义(P0.05)。结论:常规MRI联合最小ADC值有助于鉴别诊断颈部转移性淋巴结与淋巴瘤。
[Abstract]:Objective: to evaluate the value of conventional MRI combined with minimum ADC value in differential diagnosis of metastatic lymph nodes and lymphoma in the neck. Methods: retrospective analysis was made in 10 cases (26 lesions) and 18 cases (34 lesions) of cervical lymphoma proved by histopathology. MRI features of metastatic lymph nodes, At the same time, the minimum ADC values of cervical lymphoma and metastatic lymph nodes were measured and compared. Results: the incidence of cystic degeneration in the cervical lymphoma group was 8% lower than that in the metastatic lymph node group (P 0.05), and the incidence of perifocal exudation in the lymphoma group was 27% lower than that in the metastatic lymph node group. The minimum ADC value in lymphoma group was lower than that in metastatic lymph node group. It was 0.58 卤0.12 脳 10 ~ (-1) 脳 10 ~ (-3) / m ~ (-2) / s, respectively. The difference was statistically significant (P < 0.05). Conclusion: routine MRI combined with minimum ADC value is helpful for differential diagnosis of metastatic lymph nodes and lymphomas in the neck.
