The Value of DWI and DCE-MRI in the Diagnosis and Staging of Cervical Cancer in Middle-aged and Elderly People
Objective To investigate the value of diffusion weighted imaging(DWI)and dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI)in the diagnosis and staging of cervical cancer.Methods A total of forty-seven patients with cervical cancer confirmed by pathology were enrolled and subjected to routine MR,diffusion weighted imaging(DWI),and dynamic contrast-enhanced magnetic resonance(DCE-MR)scanning.By FIGO staging,they were split into two groups,stage Ⅰ+ⅡA group and the stage Ⅱ B+Ⅲ+Ⅳ group,and ROIs were drawn by two experienced radiologists to compare the differences of different quantitative parameters between the two groups.Results The variance±standard deviation of ADC value was(0.869±0.181)×10-3mm2/s in group 1,while in group 2 it was(0.716±0.1)×10-3mm2/s,which was statistically significant.The results of nonparametric tests of Ktrans,Kep and Ve in group 1and group 2 showed statistically significant differences(p＜0.05).Conclusion On the basis of conventional MRI scanning,the application of DWI and DCE-MRI can provide more comprehensive and accurate diagnosis,measurement and the staging of tumor assessment in cervical cancer,which has important reference value for the development of personalized treatment plans in clinical practice.
