Figure 4From: Early assessment of high-intensity focused ultrasound treatment of benign thyroid nodules by scintigraphic meansExemplary scintigraphical image. Exemplary scintigraphic imaging of a hot nodule (A) pre- and (B) 1 day post-HIFU ablation. Nodular 99mTc-pertechnetate uptake reduction as well as non-nodular uptake recovery due to ceased suppression by the focal autonomy (circle) is clearly visible.Back to article page
