A papillary thyroid carcinoma located in the right lobe. a CDI and b PDI show peripheral and internal vascularity of the nodule, with c color SMI and d monochrome SMI depicting more detailed peripheral vascularity surrounding the nodule as well as internal disordered small branching microvessels. e Pulsed Doppler (guided by monochrome SMI) established that the small branching microvasculature was real and measurable. f CEUS features of the nodule. The nodule enhances later compared with normal thyroid parenchyma, with disordered heterogeneous hypoechoic enhancement and incomplete peripheral enhancement
