Abstract
Objective To explore the significance of magnetic resonance imaging (MRI) in the preoperative diagnosis of myometrial invasion and cervical invasion of endometrial carcinoma. Methods 38 patients with endometrial cancer treated in our hospital from April 2011 to April 2014 were selected,and they were confirmed by postoperative histopathologic examination.The selected patients were given MRI examination.The sensitivity,specificity,positive pre-dictive value and negative predictive value of MRI diagnosis for myometrial invasion and cervical invasion of endome-trial carcinoma was analyzed respectively. Results The accurate rate of diagnosis of myometrial invasion using MRI was 86.8%,the rate of missed diagnosis was 25.0%,the rate of misdiagnosis was 10.0%.The sensitivity of deep myometrial invasion by the diagnosis of MRI was 75.0%,the specificity was 90.0%,the positive predictive value was 66.7%,the neg-ative predictive value was 93.1%.The accurate rate of diagnosis of cervical invasion by MRI was 65.8%,the rate of missed diagnosis was 66.7%,the rate of misdiagnosis was 26.5%.The sensitivity of cervical invasion by the diagnosis of MRI was 33.3%,the specificity was 71.9%,the positive predictive value was18.1%,the negative predictive value was 85.1%. Conclusion MRI in the preoperative diagnosis of myometrial invasion and cervical invasion for endometrial car-cinom is helpful to the selection of operating methods,and has important clinical examination significance.关键词
