OBJECTIVE: This study aimed at exploring and contrasting the clinical significances and values of MRI, CT and contrast-enhanced ultrasonography in FIGO staging of cervical carcinoma.

PATIENTS AND METHODS: The contrast-enhanced ultrasonography, CT and MRI imaging data of 348 patients with cervical carcinoma confirmed by clinical pathology were analyzed retrospectively and contrasted with pathological findings.

RESULTS: The total accuracy of MRI in cervical carcinoma staging was 79.89% (278/348), and the diagnostic accuracy of MRI in stage IB, stage II, stage III and stage IV of cervical carcinoma was 74.29% (26/35), 75.74% (153/202), 85.25% (52/61), 94.00% (47/50), respectively. The total accuracy of CT in cervical carcinoma staging was 73.28% (255/348), and the diagnostic accuracy of CT in stage IB, stage II, stage III and stage IV of cervical carcinoma was 60.00% (21/35), 69.80% (141/202), 78.69% (48/61), 94.00% (45/50), respectively. The total accuracy of contrast-enhanced ultrasonography in cervical carcinoma staging was 57.47% (200/348), and the diagnostic accuracy of contrast-enhanced ultrasonography in stage IB, stage II, stage III and stage IV of cervical carcinoma was 37.14% (13/35), 50.99% (103/202), 70.49% (43/61), 82.00% (41/50), respectively. The accuracy of MRI in the diagnosis of stage IB, stage II of cervical carcinoma was higher than that of CT and contrast-enhanced ultrasonography (p<0.05), and the diagnostic accuracy of CT was higher than that of contrast-enhanced ultrasonography (p<0.05). The differences among the three methods were statistically significant.

CONCLUSIONS: According to the results of pathological sections, there were statistically significant differences among the sensitivity and specificity of MRI, CT and contrast-enhanced ultrasonography in the diagnosis of stage IB and stage II (p<0.05). MRI has high diagnostic values in the differentiation and diagnosis of cervical carcinoma staging.
