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

Figure 1

Adjustment of C-TIRADS classification of thyroid nodule with hypoenhancement in CEUS. A 57-year-old female patient with a right thyroid nodule, maximum diameter of 10 mm, which was originally classified as C-TIRADS 4A before the adjustment based on the CEUS results. The nodule was reclassified as C-TIRADS 4B after the adjustment. (a) Two-dimensional gray scale. (b) Hypoenhancement at 17 s in CEUS. (c) Very hypoenhancement at 37 s in CEUS. (d) Diagnosed as papillary thyroid carcinoma in histopathology (HE × 100). CEUS: contrast-enhanced ultrasound; C-TIRADS: the Chinese-Thyroid Imaging Report and Data System.
