【Abstract】 ObjectiveTo explore the application value of 1.5T MRI diffusion-weighted imaging （DWI）） and computed tomography（CT） inthediferential diagnosis offemalepelvic tumors.MethodsOne hundredand fifty-two patientswith pelvic tumorswho visitedour hospitalfrom February 2O19 to March 2024 were includedas the study subjects.Allpatients underwent1.5TDWI-MRIand CTexaminations.Using postoperativepathologicalresultsas the" gold standard"for diagnosis，theresultsof1.5TDWI-MRIand CTexaminations were analyzed.Theapparentdifusion coeffcient （ADC）results inDWIexaminationsofpelvictumorsofdiffrent natures，andthediagnosticvalueofdiffrent examination methods inpelvic tumors and calculated consistency were compared.ResultsThere was no statistically significant difference （P>0.05 ）in the detection rates of cervical cancer，ovarian cancer，ovarian cysts， and uterine fibroids between the two examination methods.In the1.5TDWI-MRI examination of patientswith malignant pelvic tumors，the slow ADC valueand standard ADC value were lower thanthoseof benign patients，whilethe fast ADC value and some fast ADC values were higher than those of benign patients，with statistical diffrences（ P- <0.05）.Compared with CTexamination，1.5TDWI-MRI examination has higher sensitivity，accuracy，and negativepredictivevalue inthe diagnosis of pelvic tumors，with statistical differences P<0.05） .There was no statistical difference in specificity and positive predictive value between the two examination methods （ P> 0.05）.According to Kappa consistency analysis，the 1.5T DWI-MRI examination had a high consistency with the "gold standard"（Kappa=0.872， P <0.001）. Conclusion Compared with CTexamination，the1.5TDWI-MRI examination can effctivelyimprove thediagnostic efficiencyof pelvic tumors.Basedonchanges inADC values，thedifusionof benign and malignant tumors canbe judged，providing an effective reference for the diagnosis of pelvic tumors and worthy of promotion and application.

盆腔肿瘤发病率呈逐年上升趋势，以卵巢及子宫肿瘤发病率最高且最为常见，且发病原因较为复杂，早期无典型症状表现，大部分患者就诊时病情已至中晚期，错失最佳治疗时机，预后效果较差，不仅仅对患者生育能力及生活质量造成影响，严重者甚至危及生命安全[1，2]。（剩余6191字）
