This study aimed to investigate the diagnostic value of intravoxel incoherent motion (IVIM) diffusion-weighted imaging and diffusion kurtosis imaging (DKI) in distinguishing metastatic from nonmetastatic lymph nodes (LNs) in cervical cancer patients. The clinical and imaging data of 102 patients with cervical cancer were collected prospectively, including 38 patients with LN metastasis and 64 patients without LN metastasis. The morphological parameters, diffusion parameters and tumor markers of primary tumors and LNs were measured and compared between the two groups. The results showed that the diagnostic efficiency of diffusion parameters were not as good as morphological parameters.
