Value of Contrast-Enhanced Ultrasound in Adjusting the Classification of Chinese-TIRADS 4 Nodules

Figure 2

Adjustment of C-TIRADS classification of thyroid nodule with hyperenhancement in CEUS. A 61-year-old male patient with a left thyroid nodule, maximum diameter of 16 mm, which was originally classified as C-TIRADS 4A before the adjustment based on the CEUS results. The nodule was reclassified as C-TIRADS 3 after the adjustment. (a) Two-dimensional gray scale. (b) Hyperenhancement at 17 s in CEUS. (c) Still hyperenhancement at 37 s in CEUS. (d) Diagnosed as thyroid follicular adenoma (HE × 100). CEUS: contrast-enhanced ultrasound; C-TIRADS: the Chinese-Thyroid Imaging Report and Data System.
