(a) Thick feeding vessels can be seen surrounding left lobe nodules of thyroid before LA. (b) A laser is used to occlude feeding vessels of the nodules before LA. (c) Peripheral and internal nodule blood flow disappeared after occlusion of feeding vessels. (d) Immediate CEUS showed no enhancement inside the nodules after occlusion of feeding vessels.
