Figure 1. Ultrasound images in a 47-year-old woman with uterine myoma before and after microwave ablation therapy. (a) Sonogram obtained before microwave ablation shows a 7.0 × 5.7-cm uterine myoma (arrows) in uterine. (b) Colour Doppler Flow Image obtained before microwave ablation depicts the rich blood flow in the myoma. (c) Sonogram obtained 1 day after ablation shows that the myoma (arrows) has become heterogeneously hyperechoic; the size of the treated myoma is about 6.8 × 4.2 × 4.6 cm. (d) On a Colour Doppler Flow Image obtained 1 day after ablation, no blood signal is detected in the treated region (arrows). (e) Sonogram obtained 1 year after ablation shows that the myoma (arrows) has shrinked remarkably, and the size of the treated myoma is about 4.5 × 3.7 cm. (f) Power Doppler Flow Image obtained 1 year after microwave ablation depicts no blood signal in the myoma. (g) Contrast-enhanced sonogram obtained 1 day after ablation shows no contrast agent in the myoma, suggesting the complete necrosis of myomas (sagittal view). (h) Contrast-enhanced sonogram obtained 1 day after ablation shows no contrast agent in the myoma, suggesting the complete necrosis of myomas (transverse view).

Figure 2. MR images in a 47-year-old woman with uterine myoma after microwave ablation therapy. (a) On contrast-enhanced MR images obtained 1 day after ablation, no enhancement is seen in the treated myoma, suggesting the complete necrosis of myoma (sagittal T1WI MR). (b) On contrast-enhanced MR images obtained 1 day after ablation, no enhancement is seen in the treated myoma, suggesting the complete necrosis of myoma (axial T1WI MR).
