Abstract

Abstract:

Objective

To observe and analyze the therapeutic effect of focal uterine adenomyosis treated with percutaneous microwave ablation by contrast-enhanced ultrasound and dynamic contrast enhanced MRI (DCE-MRI).

Methods

From January 2013 to July 2016, 42 patients with focal uterine adenomyosis voluntarily underwent percutaneous microwave ablation in the tumor hospital of Liaocheng. Contrast-enhanced ultrasound and DCE-MRI were performed before and after percutaneous microwave ablation. The therapeutic effects of percutaneous microwave ablation in treatment of uterine adenomyosis lesions were observed.

Results

After percutaneous microwave ablation of the 42 cases, the ablated zone showed no enhancement with contrast-enhanced ultrasound and DCE-MRI. Contrast-enhanced ultrasound showed that the volume and ablation rate of ablated zone were (49.0±29.5) cm³ and (91.6±7.1)%, and that of DCE-MRI were (49.4±29.9)cm³ and (91.9±6.7)%, respectively. The results showed that percutaneous microwave ablation could cure focal uterine adenomyosis at the rate over 90%. Contrast-enhanced ultrasound and DCE-MRI are in accordance in observing the ablation rate.

Conclusions

Contrast-enhanced ultrasound can accurately show the ablation rate of focal uterine adenomyosis treated with percutaneous microwave ablation, which is quite consistent with DCE-MRI. Contrast-enhanced ultrasound has its advantages such as identifying the lesions which need immiedately supplemental ablation.
