Value of MRI and diffusion-weighted imaging in diagnosing normal-sized pelvic lymph nodes metastases in patients with cervical cancer.

The short-axis diameter, ratio of short-to-long-axis diameter and ADC of lymph nodes have moderate value in the diagnosis of the metastases of the normal-sized lymph nodes for the patient with cervical cancer as the sole indices. The combined evaluation of D, D and ADC is much more valuable in the detection of metastatic lymph nodes.
