Figure 19b. Uterine leiomyoma treated with myomectomy. (a) Sagittal T2-weighted image obtained before myomectomy shows a submucosal leiomyoma (arrow) in the anterior wall of the uterus. (b) Sagittal T2-weighted image obtained 6 months after myomectomy shows that the thickness of the myometrium has become normal. The transverse postoperative scar is seen as a low-signal-intensity line in the anterior myometrium (arrowhead).
