Objective To discuss the application value of DWI combined with T2WI of high resolution MRI in pelvic lymph node metastasis of cervical cancer. Methods Thirty-two cases with cervical cancer, which admitted in our hospital from October 2014 to February 2016, were selected as the research object. All patients were confirmed cervical cancer by surgery and pathology. Among these cases, 33 cases were squamous cell carcinomas, 1 case was gland scale cancer, 1 case was adenocarcinoma. All patients were preoperatively examined by DWI combined T2WI of high-resolution MRI. The Pelvic lymph node metastasis of cervical cancer was diagnosed according to the result of image and apparent diffusion coefficient (ADC) value of the lymph nodes. The average ADC value and minimum ADC value of non-metastasis lymph nodes and metastasis lymph node were compared. Results MRI examination preoperatively revealed 95 pelvic lymph nodes with short diameter greater than 0.8 cm and 108 lymph nodes with definite metastases, it was no significant different compared with the pathological results(P>0.05). The T2 signal intensity of metastatic lymph nodes was slightly higher than the nonmetastatic lymph nodes, but it had no significant difference (P>0.05). The average ADC value and the minimum ADC value of metastatic lymph nodes were significantly lower than that of non-metastatic lymph nodes, the difference was statistically different(P<0.05). Conclusion DWI combined with T2WI of high-resolution MRI can clearly show pelvic lymph node metastasis of cervical cancer. Its accuracy in identification with nonmetastasis lymph nodes is higher. At the same time, it can judge whether pelvic lymph node is invaded by cervical cancer with the quantitative analysis of the ADC values. This technique has clinical application value.
