MRI is more valuable than CT in the diagnosis of cervical cancer

To analyze the diagnostic values of CT and MRI for cervical cancer.

The clinical data of 83 patients with cervical cancer and 16 patients with cervicitis admitted to Zhejiang Putuo Hospital from January 2017 to December 2021 were retrospectively analyzed. Among them, 18 patients receiving CT examination were categorized as the CT group, and the remaining 81 patients with MRI examination were the MRI group. In total, 83 patients were finally diagnosed with cervical cancer through pathologic examination. The diagnostic values of CT and MRI for cervical cancer staging and pathologic features were analyzed.

Compared to CT, the sensitivity and accuracy of MRI in diagnosing cervical cancer were higher (P<0.05), as was its detection rate in the diagnosis of stage I and II (P<0.05), but the difference in the detection rate of stage III was not statistically significant. In addition, among the 83 cases of cervical cancer, it was confirmed by surgical and pathological examination that 41 cases experienced parametrial invasion, 65 had interstitial invasion, and 39 had lymph node metastasis. The detection rate of MRI in the diagnosis of interstitial and parametrial invasion was also markedly higher than that of CT (P<0.05), but the difference in the lymph node metastasis detection was not significant.

MRI can clearly display the structure of various layers of the cervix and its lesions. It is more accurate in clinical diagnosis, staging, and evaluation of pathologic features of cervical cancer compared to CT, and is available on a more reliable basis for diagnosis and treatment.
