Figure 2. The location of the endopelvic fascial edema. (a-d) MR images before USgHIFU ablation. (e) Anterior wall fascial edema; (f) posterior wall fascial, right lateral wall fascial, peri-vesical fascial, and perirectal fascial edema; (g) posterior wall fascial, left lateral wall fascial edema; (h) peri-uterine fascial, posterior wall fascial, and perirectal fascial edema.

Figure 3. A 44 years old patient with fibroid. (a-d) MRI images before USgHIFU ablation. (e-h) MRI images after USgHIFU ablation. (a) Pre-USgHIFU a sagittal T2WI image showed a posterior wall fibroid that is almost hyperintense on T2WI. (e-f) Fascial edema was shown as a high-intensity signal on T2WI and diffusion-weighted imaging (arrow).
