摘　　要：目的探讨女性子宫癌肉瘤的临床及MRI表现特点,提高MRI的诊断符合率。方法回顾性分析经我院手术及病理证实的12例子宫癌肉瘤的患者的临床及MRI影像资料,讨论并分析其临床及MRI表现特点。结果本组12例患者中,T1WI表现呈等、低信号为主,T2WI表现高、等信号为主,DWI表现呈高、低信号为主,合并出血时T1WI、T2WI、DWI均呈高、等、低混杂信号,6例动态增强扫描病灶均表现为动脉期不均匀强化,低于或等于子宫肌层,静脉期渐进性强化,延迟期强化低于子宫肌层。绝经后与未绝经两组间癌肉瘤的实性成分的ADC值无明显统计学差异(P>0.05)。癌肉瘤与子宫肌瘤两组间的实性成分ADC值的有显著统计学差异(P<0.05)。结论子宫癌肉瘤的MRI动态增强扫描表现具有一定的特点,DWI序列ADC值的测定有助于与子宫肌瘤的鉴别诊断。Objective To investigate the clinical and MRI features of women's uterine carcinosarcoma and improve the diagnostic accuracy of MRI.Methods Retrospective analysis of clinical and MRI imaging data of 12 patients with uterine carcinosarcoma confirmed by surgery and pathology in our hospital,discussed and analyzed clinical and MRI features.Results Among the 12 patients in this group,T1WI showed equal,low signal-based,T2WI high,iso-signal-based,DWI performance was high and low signalbased,combined bleeding when T1WI,T2WI,DWI were high,equal,low mixed signal.Dynamic enhancement scanning showed that all lesions in 6 cases were heterogeneously enhanced in the arterial phase,lower than or equal to the myometrium,progressive enhancement in the venous phase,and enhancement in the delayed phase below the myometrium.There was no significant difference in the ADC values of solid components of carcinosarcoma between postmenopause and non-menopause groups(P value=0.583).There was a statistically significant difference in the ADC values of solid components between carcinosarcoma and uterine fibroids(P value=0.000).Conclusion The MRI dynamic enhanced scan of uterine carcinosarcoma has certain characteristics.The determination of ADC value of DWI sequence is helpful for the differential diagnosis of uterine fibroids.
