Value of Multilayer Spiral CT in Differential Diagnosis of Benign and Malignant Ovarian Cystic Gland Tumors
Objective:To investigate the clinical value of multilayer spiral CT(MSCT)in the differen-tial diagnosis of benign and malignant ovarian cystic gland tumors.Methods:A total of 89 patients with ovarian cystic gland tumors admitted to our hospital from January 2020 to December 2022 were selected.All patients underwent both ultrasound and MSCT examinations,with pathological examination as the gold standard.Kappa test was used to assess the agreement between ultrasound,MSCT,and pathological diagno-sis.Differences in tumor diameter and CT values measured by MSCT were compared between benign and malignant patients.Additionally,differences in imaging features between benign and malignant tumors were also compared.Results:Of the 89 patients,40 were pathologically confirmed as malignant,and 49 were confirmed benign.Among them,34 cases were detected by ultrasound,with a positive rate of 85.00％(34/40),while 39 cases were detected by MSCT,with a positive rate of 97.50％(39/40).The sensitivity and accuracy of MSCT in differential diagnosis of ovarian benign and malignant tumors were higher than that of ultrasound examination(P＜0.05).The Kappa test showed excellent agreement between both ultrasound and MSCT diagnosis compared to pathological examination(kappa value=0.770,0.932,P=0.000,0.000).The tumor diameter and CT value of maglignant patients were(12.41±1.25)cm and(7.25±0.92)HU,re-spectively,which were higher than those of benign patients[(10.12±1.19)cm and(6.39±0.75)HU](P＜0.05).Malignant tumors also exhibited a higher proportion with irregular tumor shape,uneven enhance-ment density,abdominal effusion,and tumor separation compared to benign tumors(P＜0.05).Conclusion:MSCT has high value in the differential diagnosis of benign and malignant ovarian cyst gland tumors,which can improve the accuracy of differential diagnosis and prevent delays in patient treatment.
