Application of Magnetic Resonance Imaging in the Diagnosis and Clinical Staging for Cervical Cancer

[Purpose] To evaluate the application value of magnetic resonance imaging(MRI)in the diagnosis and clinical staging for cervical cancer. [Methods] A total of 84 cases with cervical cancer diagnosed by cervical biopsy were staged pre-operation and examined by MRI 2 weeks before operation. According to FIGO standards and with pathology as golden standard for diagnosis,clinical and MRI staging were compared with post-operative pathology to evaluate the diagnostic value of MRI pre-operation in cervical cancer.[Results] The diagnostic accuracy of clinical staging was 61.9%,and the accuracy,sensitivity and specificity for stage Ⅱb were 73.81%,47.06% and 80.6% respectively. The diagnostic accuracy of MRI staging was 86.9%,and the accuracy,sensitivity and specificity for stage Ⅱb were 91.69%,76.47% and 95.52% respectively. The accuracy,sensitivity and specificity of MRI diagnosis for lymph node metastasis were 84.52%,80.00% and 85.14% respectively. [Conclusions]MRI could clearly reveal cervical cancer invasion by multiple imaging,and might improve the accuracy of staging,and has diagnostic value for lymph node metastasis and parametrial infiltration.
