【Abstract】 Objective To analyze the clinical application value of MRI combined with color ultrasound in the diagnosis ofearly ovarian cancer.MethodsNinety female patients with suspected ovarian cancer admited to our hospital from January 2O18 to January 2O24 were colected as studysubjects.Allof them received ultra-sound and MRI imagingdiagnosis，and pathological examination wasusedasthe "gold standard"fordiagnosis.Di-agnostic results wereanalyzed，diagnosticeficacywas evaluated，andquantitativeparametersofbenignandma-lignantovarian tumors were compared with MRI.Corelation between clinical stage of ovarian cancer and quanti-tative parameters of ultrasound and MRI was also analyzed. ResultsThe ultrasound examination missed 17 cas-es and misdiagnosed 12 cases，while MRI examination missd12 cases and misdiagnosed8cases.The combined ultrasound and MRI examination missed 3 cases and misdiagnosed 2 cases.Ultrasound missed diagnosis in17cases， misdiagnosis in 12 cases，MRI missed diagnosis in12cases，misdiagnosis in8cases，combined examina-tion missd diagnosis in 3 cases，misdiagnosis in2cases.The sensitivity，specificity，positive predictivevalueand negative predictivevalueof combinedultrasound and MRI diagnosis were higher than thatof single diagnosis.TheRI and PI indexes of malignant ovarian tumor were lower than those ofbenign ovarian tumor，and the Kep and Ktrans indexes were higher than thoseof benignovarian tumor.Theclinical stageofovariancancerwas negativelycorrlatedwithPIandRI，butpositivelycorrelatedwithKepandKtrans（ P <0.05）.ConclusionThe combination of MRI and color ultrasound in the diagnosis of earlyovariancancer has high clinical diagnosticvalue.Through theanalysis of quantitative parameters of ultrasoundand MRIofovarian tumors，indicating thatquantitativeultra-soundand MRIcan evaluate the stage of ovarian cancer.
