【Abstract】ObjectiveTo explore the application valueof 1.5T MRIdiffsion-weighted imaging （DWI） and computed tomography （CT）inthediferential diagnosisof female pelvic tumors.MethodsOne hundredandfty-two patientswith pelvic tumors who visitedour hospital from February 2O19 to March 2O24 were includedas the study subjects.All patients underwent 1.5TDWI-MRI and CT examinations.Using postoperative pathological results as the "gold standard"for diagnosis，theresults of 1.5T DWI-MRIand CT examinations were analyzed.Theapparent difusioncoefficient （ADC）results inDWIexaminations of pelvictumorsofdiferentnatures，andthediagnostic value of diferent examination methods inpelvictumorsand calculatedconsistency were compared.ResultsThere was no statistically significant diffrence （P>O.O5）inthedetectionratesof cervicalcancer，ovariancancer，ovariancysts，and uterine fibroids between the two examination methods.In the1.5TDWI-MRI examination of patients with malignant pelvic tumors，the slow ADC value andstandard ADC value were lower than those of benign patients，while the fast ADC value and some fast ADC values were higher than those of benign patients，with statistical differences （ P <0.05）. Compared with CTexamination，1.5TDWI-MRI examination has higher sensitivity，accuracy，andnegative predictive valuein the diagnosis of pelvic tumors，with statistical differences（ P <0.05）.Therewas no statistical difference in specificity and positive predictive value between the two examination methods（ P >0.05）. According to Kappa consistency analysis，the1.5T DWI-MRI examination had a high consistency with the "gold standard"（Kappa=0.872， P <0.001）.ConclusionCompared with CT examination，the1.5TDWI-MRI examination can effectively improve the diagnostic efficiency of pelvic tumors.Based on changes inADC values，the diffsion of benign and malignant tumors canbe judged，providingan effctive reference forthe diagnosisof pelvic tumorsand worthyof 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6082字）
