Study on the accuracy of MRI for cervical cancer staging / 实用放射学杂志

ABSTRACT

Objective To investigate the value of MRI in the staging of cervical cancer.Methods 9 7 patients with cervical cancer were selected,were detected by conventional MRI sequence (T1 WI,T2 WI)and DWI scan.Results Routine MRI diagnosis of cervical cancer staging and pathological stage Kappa value were 0.840,P＜0.05,the consistency was excellent.The accuracy rate of routine MRI for cervical cancer staging was 89.69%,and the accuracy rates of stageⅠ,stageⅡand stageⅢwere 80.95%,89.74% and 94.59% respectively. The ADC value of stage Ⅲ cervical cancer was (0.77±0.20)×10－3 mm2/s,which were significantly lower than that of stage Ⅰ and stage Ⅱ (P ＜0.05).The ADC value of stage Ⅱ cervical cancer was (0.89±0.14)×10－3 mm2/s,which was significantly lower than that of stageⅠ(P＜0.05).The ADC value of poorly differentiated cervical cancer was (0.82±0.15)×10－3 mm2/s,which was significantly lower than that of moderately high differentiation (P＜0.05).Conclusion Conventional MRI has high accuracy in the j udgment of cervical cancer staging,and has excellent consistency with pathological staging.Moreover,DWI can provide imaging reference for cervical cancer differentiation,and it is expected to be an accurate evaluation method for assessing the clinical stage of cervical cancer staging.
