infiltration the accuracy was 84,1%, sensitivity was 28,6%, specificity was 91,8%. Nodal metastases were detected in 15,9% patients (11,6% in PLN and 4,3% PLN&PALN). The accuracy of the MRI for the detection of nodal metastasis was 75,4%, sensitivity 30,8%, specificity 84,2%. Further analysis evaluated the impact of the following features on the MRI efficiency: histological type, patient age, presence of myomas and the reference status of the radiology center. Conclusion Unsatisfactory results of MRI imaging, particularly that overestimate the local infiltration, lead to performing too extensive lymphadenectomy, especially that the ability of detecting LN metastasis by MRI has low rate. All quality bias should be taken into consideration when analyzing the results of the MRI to tailor the surgical treatment.
