Abstract:
Objective To observe the value of training about ovarian-adnexal reporting and data system((O-RADS)for risk stratification of adnexal lesions diagnostic efficacy of different seniority physicians before and after training.Methods A total of 575 O-RADS 1-5 point lesions from 470 patients who received non-contrast enhanced pelvic MR and dynamic contrast-enhanced MRI(DCE-MRI)were retrospectively included.The lesions were scored by 1 junior radiologist(radiologist A)and 1 senior radiologist(radiologist B)independently according to O-RADS risk stratification,and the results were recorded as R1 and R2,respectively.Three months later,the lesions were rescored by radiologist A and B after receiving systematic training from gynecological imaging experts,and the results were recorded as R11 and R22,respectively.Two gynecological imaging experts conducted a consensus scoring,and the results were recorded as R0.Taken O-RADS score＞3 as the criterion for malignant,the diagnostic efficacy of radiologist A and B before and after training were evaluated,while taken R0 as the reference,the intra-observer,inter-observer consistency between radiologist A and B,as well as their consistency with R0 were calculated.Results The diagnostic sensitivity and specificity of R0 was 95.21%and 93.14%,respectively.The diagnostic sensitivity of radiologist A before and after training was 92.22%and 95.21%,with specificity of 83.33%and 89.46%,respectively.For radiologist B,the sensitivity before and after training was 95.81%and 95.21%,with specificity of 92.89%and 91.91%,respectively.Good intra-observer consistency of O-RADS score was observed both in radiologist A and B,with Kappa value of 0.845 and 0.884,respectively,which also noticed between radiologist A and B,with Kappa value of 0.761,and the Kappa value of R1,R2 and R0 was 0.781 and 0.911,respectively.After training,the inter-observer consistency of radiologist A and B increased,and Kappa value of R11,R22 and R0 was 0.844 and 0.915,respectively.Conclusion Training about O-RADS for risk stratification was helpful to improving diagnostic specificity of benign and malignant adnexal lesions,especially for junior radiologists.
