%A Ngoc, Doan Van %A Van Lenh, Bui %A Dieu, Bui %D 2020 %T The Value of Magnetic Resonance in Assessment of Size, Invasion, Metastasis and Cervical Cancer Stage Classification %K %X This study investigates the value of magnetic resonance (MR) in assessing size, invasion, lymph node metastasis and cervical cancer stage classification in 117 patients who underwent surgery for whole hysterectomy and pelvic lymph node dredge in Vietnam National Cancer Hospital from July 2016 to August 2018. The study results show that tumor size accuracy (Acc) was 93.2%; vaginal invasion Sp was 98.2%; Acc, 96.6%, NPV, 98.2%; parametrial invasion Sp, 98.2%; Acc, 98.3%, NPV, 100%; pelvic wall invasion Acc , 98.3%; Sp was 115/116, 99.1%; NPV, 99.1%; metastatic lymph node Sp, 98.0%; Acc, 88.9%; NPV, 89.8%. The Acc of the value of MR in cervical cancer stage diagnosis from stage IB was 96.1%; and the overall Acc was 82.9%. The study results also show that the use of MRI in combination with clinical examination in size, invasion, metastasis and cervical cancer stage classification is necessary to improve the accuracy of the diagnosis.      Keywords  Cervical cancer, MRI of cervix.
