Clinical value of magnetic resonance diffusion weighted imaging and dynamic enhanced imaging in endome-trial carcinoma staging / 中国基层医药

ABSTRACT

Objective To study the value of magnetic resonance diffusion weighted imaging (DWI)and dynamic enhanced imaging (DCE)in endometrial carcinoma staging.Methods 200 cases with endometrial carcinoma were selected,DWI and DCE were given before operation.The diagnostic value of two kinds of examination methods for the diagnosis of endometrial carcinoma in general and basic level was compared.Results The overall accuracy of muscle invasion of magnetic resonance DWI was 91.5%(183 /200),which was significantly higher than 77.5%(155 /200)of magnetic resonance DCE,the difference was statistically significant (χ2 =11.231,P <0.05 ).The accuracy,sensitivity and positive predictive value of the magnetic resonance DWI superficial and deep muscular layer were significantly higher than those of the magnetic resonance DCE (χ2 =9.283,8.231,9.021,8.927,8.142, 9.405,all P <0.05).Compared with pathological results,Kappa value of magnetic resonance DWI was 0.807,Kappa value of magnetic resonance DCE was 0.587.Conclusion Magnetic resonance DWI compared with magnetic reso-nance DCE,the accuracy and sensitivity of the infiltration of endometrial carcinoma was higher.
