Introduction: In this study, we evaluated the diagnostic value of imaging parameters in para-aortic lymph node involvement in patients with cervical cancer.

Materials and Methods: In this study, patients with cervical cancer referred to the imaging department of Shohada Tajrish Hospital were examined using convenience sampling. All patients underwent abdominal and pelvic MRI for staging before starting treatment. The patient's demographic and clinical information was recorded based on a questionnaire and MRI information, FIGO stage, and postoperative pathology were collected. In preoperative MRI, the largest tumor diameter, fornix involvement, and lymph node parameters, and tumor and lymph node characteristics were evaluated in terms of heterogeneity in T2WI, DWI and ADC features, and dynamic contrast enhanced appearance, and were reported by a radiologist who was familiar with the field of gynecological oncology imaging and unaware of the pathology results.

Results: According to the results, the average of all three indices T2 SI, DCE and ADC were higher in patients with para-aortic lymph node involvement, but these differences were not statistically significant (p<0.05). According to the results, it was shown that only the necrotic variable was statistically significant (p=0.001). While other variables including tumor volume, menopause, conglomerated, T2 SI, DCE and ADC did not show any statistical relationship (p<0.05).

Conclusion: In general, it can be said that there was no significant relationship between tumor parameters and MRI with para-aortic lymph node involvement in patients. However, further studies are needed to investigate this issue in the future.
