| 摘 要： | 目的 总结不同临床分期宫颈癌的超声造影表现.方法 应用反向脉冲谐波超声造影技术,联合时间-强度曲线(TIC),分析48例经病理证实的不同临床分期宫颈癌患者的超声造影资料,总结宫颈癌超声造影增强方式.结果 宫颈癌超声造影表现为增强早期病变内造影剂灌注明显早于子宫肌层,呈均匀或不均匀增强;增强晚期造影剂消退早于子宫肌层,与正常宫体形成明显的界限,可清晰显示病变轮廓及对周围组织的浸润程度.结论 超声造影能较准确地判断宫颈癌分期及肿瘤浸润范围,在一定程度上弥补常规超声在宫颈癌诊断和分期中的不足.

| Abstract: | Objective To summarize the manifestations of contrast-enhanced ultrasound in different stage cervical cancer.Methods Contrast-enhanced ultrasound using pulse inversion harmonic imaging and on time-intensity curve was undergone in 48 cases with pathologically diagnosed cervical cancer, data were analyzed to summarize the features of contrast enhancement.Results Lesion tissue was enhanced homogeneously or heterogeneously earlier than myometrium.Lesion exhibited earlier washout than that of myomerium in the later phase, while the peripheral area still remained hyper-enhancement.Lesion invasion and borderline could be determined in ultrasound clearly.Conclusions Contrast-enhanced ultrasound could accurately diagnose the stage of cervical cancer and lesion invasion.It may compensate for the shortcomings of conventional ultrasound in the diagnosis of cervical cancers and disease stage. |
