We evaluat ed the diagnostic performance of MRI for the parametrial invasion and LN involvement using surgicopathologic findings as the reference standard Results The sensitivity , specificity and accuracy of MRI in det ecting parametrial invasion w ere 800% , 914% and 889% respectively; while clinical examinat ion were 500% , 829% and 756% respectively The sensitivity , specificity and accuracy of MRI in detecting LN involvement was 556% , 944% and 867% respectively Conclusion Preoperat ive MRI is more useful for the evaluation of parametrial involvement in cervical cancer than clinical examination Preoperat ive MRI shows high speci ficity, however, the sensitivity is low for detecting LN involvement in cervical cancer Further studies are necessary to im prove the sensit ivit y [Key ords] Cervical cancer; Lymph node; Magnetic resonance imaging MRI * 陈对梅, 王 峻 , 牛金亮, 郑 英 ( , 030001) [ ] MR 45 MR , , , 3 MRI MRI 800% , 914% ,
