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.
