Methods A total of 113 patients with IB1 to IIB stage cervical cancer underwent conventional MRI and DWI, and radical hysterectomy plus pelvic and/or paraaortic lymph node dissection. Results Pathological examination showed that lymph node metastases occurred in 19 cases (16.8%). The sensitivity, specificity, and accuracy of conventional MRI and DWI for determining lymph node metastasis in cervical cancer were 68.4% (13/19), 96.8% (91/94), and 92.0% (104/113), respectively. Conclusion There is a high predictable accuracy of conventional MRI and DWI for determining lymph node metastasis in cervical cancer. Key words: cervical cancer; magne
