From: Using preoperative ultrasound vascularity characteristics to estimate medullary thyroid cancer
Two examples illustrating the vascularity features of penetrating branching vascularity. (A) A case of a 57-year-old man whose ultrasound showed a 1.2-cm solid thyroid nodule in the right lobe. (B) CDFI of the lesion. (C) A case of a 60-year-old woman whose ultrasound showed a 1.6-cm solid thyroid nodule in the right lobe. (D) CDFI of the lesion. Histological pathology confirmed that these two nodules were MTC.
