摘　　要：目的探讨富于细胞型子宫平滑肌瘤的MRI征象特点,提高其MRI诊断准确性,为临床治疗方案的制定提供依据。方法收集18例经病理证实子宫富于细胞型平滑肌瘤的资料,对其病理特点及MRI表现进行回顾性分析。结果 16例病灶T1WI上呈均等信号,T2WI上呈均匀等或稍高信号,2例表现为高、等、低混杂信号;16例DWI为高信号,2例为等信号;增强扫描15例早期明显强化,各期强化均高于子宫肌层,3例为中晚期强化。结论"T1WI等信号,T2WI等或稍高信号,DWI高信号,早期强化"是子宫富于细胞型平滑肌瘤的MRI特征性表现,MRI是诊断此病的重要检查方法。Objective To investigate MRI characteristic manifestations of cellular uterine leiomyoma,and to improve the diagnostic accuracy of MRI,so as to provide basis for the development of clinical treatment plan.Methods The data of 18 cases of patients diagnosed of cellular uterine leiomyoma by pathological examination were collected and analyzed retrospectively.The pathological features and MRI manifestations of cellular uterine leiomyoma were analyzed retrospectively.Results Equal signals on T1WI and homogeneous or slightly high signals on T2WI were observed in 16 cases,and mixed high and low signals in 2 cases.Among 18 patients,high signals on DWI were seen in 16 cases and equal signals on DWI in 2 cases;significant enhancement was noted in 15 cases in early phase of enhanced MRI scanning,with enhancement in all phases higher than that of myometrium,and enhancement was noted in 3 cases in the middle and late phases.Conclusion"Equal signals on T1WI,homogeneous or slightly high signals on T2WI,high signals on DWI and enhancement in early phase"are MRI characteristic manifestations of cellular uterine leiomyoma,and MRI is an important examination method for the diagnosis of the disease.
