Figure 9d. MR images of partial uterine septum. (a) Coronal oblique fast spin-echo T2-weighted image (6000/120) shows flat external uterine contour with prominent upper myometrial component (short arrow) and small lower fibrous component (long arrow). (b) Coronal oblique fast spin-echo T2-weighted image (6100/110) shows partial septum with insinuated leiomyomas (arrow). (c, d) Coronal oblique fast spin-echo T2-weighted images (6000/105) show partial septum with extensive adenomyosis (curved arrows). Note concave external uterine contour (straight arrow).
