摘　　要：目的:探讨MRI在侵袭性葡萄胎诊断中的临床应用价值。方法:收集7例行MRI扫描诊断为侵袭性葡萄胎并经手术和病理证实的病例,进行对比分析。结果:多序列MRI扫描显示,7例患者子宫均有不同程度增大,肌层不均匀增厚,宫腔和肌层内见长T1、长T2信号的囊性和等信号结节影,外肌层和盆腔内可见大量的血管流空信号。5例子宫腔内见短T1、长T2信号出血灶,3例子宫肌层见斑点状短T1、长T2信号出血灶。4例双侧附件出现实性或囊性肿块。T1WI增强扫描表现为宫腔、肌层及附件病灶呈环形和结节状强化。结论:侵蚀性葡萄胎的MRI表现具有特征性,有助于临床诊断和治疗。Objective To investigate the clinical value of magnetic resonance imaging（MRI） in diagnosing the invasive mole.Methods Collect 7 patients with invasive mole diagnosed by MRI and confirmed by surgery and pathology.Results Enlargement of the uterine cavity and irregularly thickened myometrium were observed in all seven cases with long Tl and long T2 cystic lesions and iso-intense nodules in the uterine cavity and myometrium and signal void of vessels in the deep myometrium and pelvic cavity.Short T1 and long T2 Hemorrhagic lesions were found in the uterine cavity in 5 cases.Spotty short Tl and long T2 singnal were found in myometrium in 3 cases.Solid or cystic masses were found in bilateral adnexas in 4 patients.Gadolinium-enhanced T1-weighted imaging showed rim and nodular enhancement in all 8 cases.Conclusion The invasive mole displayed characteristic MRI findings,contributing to the diagnosis and treatments.
