Figure 11f. Fibroid regrowth. (a, b) Sagittal single-shot fast SE T2-weighted (4.4/64) (a) and gadolinium-enhanced gradient-echo T1-weighted (160/4.1, 80° flip angle) (b) MR images obtained prior to UAE show a dominant intramural fibroid within the anterior uterine body. (c, d) On sagittal single-shot fast SE T2-weighted (4.4/64) (c) and gadolinium-enhanced gradient-echo T1-weighted (160/4.1, 80° flip angle) (d) MR images obtained 5 months after UAE, the dominant fibroid has decreased in size and vascularity. A nidus of enhancement in the fibroid continued to grow at 1-, 2-, and 3-year intervals after UAE. (e–g) Axial (e) and sagittal (f ) single-shot fast SE T2-weighted MR images (4.4/64) and a sagittal gadolinium-enhanced 3D T1-weighted VIBE MR image (4.5/1.9, 15° flip angle) (g) obtained 4 years after UAE show regrowth of the dominant fibroid without areas of infarction.
