Figure 1.
A spherical lesion with enhanced blood flow.
Before treatment, a spherical lesion and enhanced blood flow is shown by contrast ultrasound.
Figure 2.
A spherical lesion with decreased volume and low blood flow.
Three months after treatment the spherical lesion's volume decreased significantly, and there is no reinforcement of blood flow at the lesion with strengthening in tissues surrounding the lesion.
Figure 3.
A spherical lesion with significantly decreased volume and no blood flow.
Six months after treatment there is a significant decrease in the volume of the spherical lesion, with no reinforcement of its blood flow. There is no evident increase in blood flow of tissues surrounding the lesion.
Figure 4.
A spherical lesion with no blood flow.
One year after treatment, the volume of the spherical lesion decreased mildly, but with no reinforcement of its blood flow. No blood flow was shown in the tissue surrounding the resection area.
