Materials and Methods: Eighteen CS and 30 low risk EC confirmed by surgery were retrospectively analysed. The following MRI features of the tumors were evaluated: tumor morphology, maximum tumor diameter, ET/AP, the integrity of junction zone, hemorrhagic, necrotic/cystic components, flow voids, mean ADC values (mADC), relative ADC values (rADC), maximum relative enhancement ratio (MRER) and Washout. Results: There were significant differences between CS and EC in the following qualitative parameters: hemorrhagic, necrotic/cystic components and flow voids (P＜0.05). For quantitative MRI parameters, maximum dimension, ET/AP, MRER and Washout could significantly distinguish CS from low risk EC (P＜0.05). According to the receiver operating characteristic (ROC) curves, when the cut-off values of maximum dimension, ET/AP, MRER and Washout were 37.5 mm, 0.474, 1.299 and 0.021, the sensitivity and specificity of the diagnosis were 83.3%, 83.3%; 88.9%, 83.3%; 94.4%, 96.7%; 100.0%, 72.2%; respectively. Conclusions: Qualitative and quantitative MRI parameters were of great value in differentiating CS from low risk EC. The maximum diameter, ET/AP, MRER and Washout could be used as optimization parameters to provide imaging information for adequate clinical treatment.Key words uterine neoplasms; carcinosarcoma; endometrial neoplasms; magnetic resonance imaging; diagnosis, differential子宫癌肉瘤(uterine carcinosarcoma，CS)是由上皮细胞和间质成分组成的去分化型子宫内膜癌[1]。因复发率高，生存率低[2]，ESMO-ESGO-ESTRO共识会议将CS列为高危型子宫内膜癌(endometrial carcinoma，
