Objective To evaluate the clinical value of 3.0T MRI functional imaging in preoperative staging of cervical cancer. Methods 108 patients with cervical cancer treated in the Affiliated Hospital of Zhengzhou University/Nanyang Central Hospital from September 2012 to May 2017were selected as the subjects. All patients underwent transverse axial and sagittal scanning performed with GE 3.0T magnetic resonance scanners by the fast spin echo (FSE) sequence. The transverse axial echo planar imaging (EPI) sequence was used for diffusion weighted imaging (DWI) scanning.The stage and differentiation degree of cervical cancer were determined according to the imaging findings, and the results were compared with the results of pathological diagnosis after operation. Results There was no significant difference in preoperative MRI staging and postoperative pathological staging (χ2 =2.77, P>0.05). The accuracies of MRI in the diagnosis of clinical stage I b, stage II a, stage II b, stage III a, stage III b, stage IV a and stage IV bof cervical cancer were 84.62% 87.50%, 75.00%, 80.00%, 77.78%, 86.67% and 90.91%, respectively while the sensitivities were 78.57%, 82.35%, 83.33%, 75.00%, 82.35%, 81.25% and 100.00%.There was no statistically significant difference in differentiation degree diagnosed by preoperative MRI and postoperative pathology (χ2 =0.09, P>0.05). The accuracies of MRI in the diagnosis of low to moderate differentiation and high differentiation of cervical cancer were 90.67% and 80.00%, respectively, and the sensitivities were 93.15% and 80.00%, respectively.Conclusion 3.0T MRI functional imaging is of high accuracy and specificity for accurate staging of cervical cancer, and it can be used to evaluate thedifferentiation degree.
