Figure 20f. Uterine leiomyomas treated with UAE. (a-c) Sagittal T1-weighted (a), T2-weighted half-Fourier single-shot turbo spin-echo (b), and contrast-enhanced T1-weighted (c) images obtained before UAE show three uterine leiomyomas (arrows in b and c). (d-f) Corresponding images obtained 3 months after UAE show changes in the signal intensity of the leiomyomas. (d) T1-weighted image shows that the leiomyomas (arrows) now have high signal intensity. White circles = regions of interest for signal intensity measurement. (e) T2-weighted half-Fourier single-shot turbo spin-echo image shows a more discrete interface between the leiomyomas (arrows) and the myometrium. (f) Contrast-enhanced T1-weighted image shows significantly diminished vascularity in all three leiomyomas (arrows). Note that myometrial enhancement is maintained. (Case courtesy of Susan M.
