Application Observation of Dynamic Contrast-enhanced Magnetic Resonance Imaging in Ovarian Cancer
Objectie To explore the application effect of dynamic contrast-enhanced resonance imaging in ovarian cancer.Methods 86 suspected ovarian cancer patients from June 2020 to July 2022 were selected as the study subjects,and all patients underwent dynamic contrast-enhanced magnetic resonance imaging.The pathological examination results were used as the"gold standard"to analyze the diagnostic efficacy of this method;According to the selected location,the confirmed patients are divided into three groups of interest:the entire tumor,tumor hotspots,and surrounding tissues.Complete dynamic contrast-enhanced resonance imaging image post-processing with the help of the Tissue 4D software package,and compare quantitative parameters of each group.Results 52 suspected ovarian cancer patients were diagnosed through the"gold standard"examination,with a diagnosis rate of60.47％.46 positive patients underwent dynamic contrast-enhanced magnetic resonance imaging,with an accuracy of 83.72％(72/86),sensitivity of 80.77％(42/52),specificity of88.24％(30/34),positive predictive value of 91.30％(42/46),and negative predictive value of 75.00％(30/40);There were 36 cases of epithelial ovarian cancer and 16 cases of ovarian borderline tumors.The dynamic contrast-enhanced magnetic resonance imaging quantitative parameters Ktrans,Ve,Kep,and iAUC levels in epithelial ovarian cancer patients were higher than those in epithelial ovarian cancer patients(P＜0.05);The levels of tumor hotspots Ktrans,Ve,Kep,and iAUC in ovarian cancer patients were higher than those in the surrounding tissues and the entire tumor(P＜0.05).Conclusion Dynamic contrast-enhanced resonance imaging has high diagnostic efficacy in ovarian cancer patients,which can understand the permeability of tissue microvessels,indirectly reflect the generation of tumor blood vessels,and monitor tumor hotspot evaluation results more accurately.
