Diagnosis of Multi-slice Spiral CT Enhanced Scanning in Borderline and Invasive Ovarian Tumor / 中国医学影像学杂志

ABSTRACT

Purpose To investigate the diagnostic value of multi-slice spiral CT (MSCT) enhanced scanning in borderline and invasive ovarian tumor,and to provide valuable image evidence for clinical treatment.Materials and Methods One hundred and one patients with pathological-confirmed borderline and invasive ovarian tumor in the First Affiliated Hospital of Jinzhou Medical University from October 2012 to October 2016 were selected,and the preoperative abdominal MSCT enhanced imaging,clinical and pathological data were retrospectively analyzed.The MSCT imaging was observed,and the prediction model of MSCT differentiating borderline and invasive ovarian tumor was established.Results The differences of onset age,menopausal status,tumor solid components,maximum diameter,septa and margin were all statistically significant between borderline and invasive ovarian tumor groups (P＜0.05).The prediction model of MSCT differentiating borderline and invasive ovarian tumor was established using multivariate Logistic regression,on the basis of following variables (OR＞l,P＜0.05)tumor size,solid components and septa.The sensitivity and specificity of the prediction model were respectively 81.3％ (95％ CI0.622-1.000) and 85.7％ (95％ CI0.741-0.973) in predicting borderline ovarian tumor for patients before menopause,and respectively 92.1％ (95％ CI0.835-1.000) and 91.7％ (95％ CI0.761-1.000) for those after menopause.Conclusion MSCT enhanced scanning is helpful to differential diagnose of borderline and invasive ovarian tumor,and it has important significance for clinical treatment and prognosis evaluation.
