Fig. 3

An isoechoic thyroid nodule located in the right lobe. a CDI and b PDI show some peripheral vascularization around the nodule. c Color SMI and d monochrome SMI show complete peripheral vascularization surrounding the nodule, with internal microvascularization and small branching details. e Pulsed Doppler (guided by monochrome SMI) established that the small branching microvasculature was real and measurable. f CEUS shows ring enhancement around the nodule and homogeneous internal enhancement. Histology: adenoma
