子宫肌瘤的静脉超声造影研究

Study of intravenous contrast enhanced ultrasound for uterus myoma

目的:探讨子宫肌瘤的静脉超声造影特征,为鉴别诊断子宫肌瘤和其他子宫疾病困难时提供新的手段。方法:经病理证实的子宫肌瘤25例共30个病灶进行静脉超声造影,采用意大利Bracco公司生产的第二代声学造影剂Sonovue,造影时重点观察、记录病灶和子宫肌层的显影顺序和充盈方式。结果:子宫肌瘤的典型造影表现为由周围逐渐向中心充盈,呈典型的环状增强,小的肌瘤可呈中心充盈方式,不呈环状增强。肌瘤玻璃样变性时变性区无造影剂灌注。结论:子宫肌瘤具有特征性的静脉超声造影表现,对鉴别诊断有重要意义。

Objective： To explore the features of uterus myoma in intravenous contrast enhanced ultrasound for the sake of differenflaring uterus myoma and other uterus diseases when in tronble Methods ： Twenty - five patients with uterus myoma were investigated using Sonovue （Bracco SPA, Milan, Italy ） . The pattern and sequence of contrast agent appearing in the lesion and myometrium were focused. Results： The typical contrast pattern of myoma is ring -enhancement and contrast agent appears from surround to centre. However, small myoma could show atypical contrast pattern. It shows no ring - enhancement and contrast agent appears from centre to surround. Addirionally, when the myoma has glassy degeneration, no contrast agent appears in the degeneration area. Conclusion： Intravenous contrast enhanced uhrasonography plays an important role in differentiating intrauterine diseases.
