Objective To explore the clinical value of magnetic resonance diffusionweighted imaging (DWI) and MR dynamic enhanced scan in the diagnosis of cervical cancer. Methods In our hospital 90 cases of patients with cervical cancer (Cancer Group) and 30 healthy volunteers (control group), the collection time from March 2016 to October 2017, apparent diffusion coefficient between the two groups DWI b=800s/ mm2 table (ADC), the value of dynamic enhanced MR scanning parameters (Ktrans: Kep: transfer coefficient, rate constant, Ve: volume fraction); clinical value and pathological results according to the calculation of single and combined application of two methods in the diagnosis of cervical cancer. Results Cervical cancer group Ktrans, Kep values were significantly higher than the control group (P<0.05), cervical cancer group ADC values were significantly lower than the control group (P<0.05). Cervical cancer and control group Ve values, The sensitivity and specificity of DWI in diagnosing cervical cancer were 85.56% and 80.00% respectively. The sensitivity and specificity of MR dynamic contrastenhanced scan in diagnosing cervical cancer were 87.78% and 86.67% respectively. The MR dynamic contrast-enhanced The sensitivity of combined DWI in diagnosing cervical cancer was 95.56% and the specificity was 93.33%. Conclusion DWI combined with MR dynamic enhanced scanning of cervical cancer can significantly improve the diagnostic sensitivity and specificity.
