子宫肌瘤的超声造影表现及其诊断价值

目的探讨子宫肌瘤的超声造影表现及其临床意义。方法采用造影剂声诺维及实时超声造影技术对29例子宫肌瘤患者进行超声造影，造影剂注射方法为团注法，观察子宫肌瘤的造影剂灌注过程及造影后声像图特点。结果子宫肌瘤表现为假包膜内血管首先充盈，后造影剂自外周向内快速充盈，瘤体内部造影剂分布均匀，消退较包膜快，而变性区无造影剂分布；浆膜下及黏膜下肌瘤可显示其蒂部血流来源于子宫动脉。结论子宫肌瘤超声造影时具有典型的声像图表现，能为子宫肌瘤尤其不典型肌瘤的诊断和鉴别诊断提供可靠证据。

Contrast-enhanced ultrasound features and clinical significance in the diagnosis of uterine myomas

Objective To explore the imaging features and clinical significance of contrast-enhanced ultrasound(CEUS) in uterine myomas. Methods Twenty-nine cases with uterine myomas were studied by CEUS accompanied with Contrast Tuned Imaging. After bonus SonoVue administration, the perfusion process and sonographic characteristics of lesions were observed. Results After agent administration, uterine myomas demonstrated peripheral enhancement of pseudocapsule, and then the entire masses were enhanced homogeneously from exterior to interior. In the later phase, uterine myomas exhibited earlier washout than pseudocapsule,while the degenerative or necrotic area depicted no agent perfusion. The feeding arteries from uterus depicted clearly in subserous and submucous myomas. Conclusions The myomas had characteristic CEUS features, which would be valuable in the diagnosis and differential diagnosis of different type myomas, especially of atypical myomas.
