Abstract

Objective: The study aims to evaluate the value of 1.5 Tesla magnetic resonance imaging (MRI) in diagnosing early-stage cervical cancer (CC) in patients who underwent radical surgery at K Hospital.  Subjects and Methods: A cross-sectional descriptive study was conducted on 106 patients with cervical tumors classified as early-stage based on MRI, who underwent radical surgery and had postoperative pathological results from January 2024 to December 2024 at K Hospital. Results: In early-stage cervical cancer (UT CTC), MRI has high value in diagnosing vaginal invasion of the upper 2/3 with sensitivity (Se) = 87,5%, specificity (Sp) = 97,9%, accuracy (Acc) = 97,1%, positive predictive value (PPV) = 77,8%, and negative predictive value (NPV) = 98,9%. MRI also shows 100% accuracy and negative predictive value for diagnosing invasion into the lower 1/3 of the vagina, pelvic sidewall, ureters, bladder, and rectum. For diagnosing pelvic lymph node metastasis, MRI demonstrates 94,3% accuracy and NPV. Regarding early-stage cervical cancer staging, MRI shows an accuracy of 90,1% for stage IB1, 93,9% for stage IB2, and 85,7% for stage IIA1. The overall accuracy is 87,7%. Conclusion: MRI is highly valuable in diagnosing assessing invasion and determining pelvic lymph node metastasis in cervical cancer patients. It plays an essential role in accurate early-stage cervical cancer staging and helps in devising the most appropriate treatment plan for patients.
