Figures

Fig. 1
Strain elastography: B-mode US image (A) showing a nodule in the right thyroid gland (arrow). This lesion showed increased stiffness on elastography (B) and the overlay image (color overlayed on B-mode) (C) with predominantly blue color (high stiffness), which was shown to be a follicular adenoma on histopathology. C, carotid artery.

Fig. 2
Strain elastography: B-mode US image (A) showing a nodule in the left thyroid gland with small areas of calcification in it (arrow). This lesion showed increased stiffness on elastography (B) and the overlay image (color overlayed on B-mode) (C) with a combination of blue and green color (moderate stiffness), which was shown to be a papillary carcinoma on histopathology.
Fig. 3
Fig. 3
Quantitative strain elastography: B-mode US image (A) showing a nodule in the left thyroid gland with cystic changes in it. ROIs were drawn on the lesion and adjacent to the carotid artery as shown in the elastography image (B). This lesion showed increased stiffness and had a thyroid stiffness index of 35, which was shown to be a papillary carcinoma on histopathology.

Fig. 4
Quantitative strain elastography: B-mode US image (A) showing a solid nodule in the left thyroid gland. ROIs were drawn on the lesion and adjacent to the carotid artery as shown in the elastography image (B). This lesion showed intermediate stiffness and had a thyroid stiffness index of 13.5, which was shown to be a follicular lesion with low probability of malignancy on cytology.

Fig. 5
SWE showing a nodule with an SWE value of 72 kPa on a transverse image (A) and an SWE ratio with the surrounding normal thyroid gland on the sagittal image (B) of 2.46, which was shown to be a papillary carcinoma in histopathology.
Fig. 6
Fig. 6
SWE showing a nodule with an SWE value of 7.2 kPa on a transverse image (A) and an SWE ratio with the surrounding normal thyroid gland on the sagittal image (B) of 0.92, which was shown to be a multinodular goiter on histopathology.
Fig. 7
Fig. 7
SWE showing a nodule with an SWE value of 13.8 kPa on a transverse image (A) and an SWE ratio with the surrounding normal thyroid gland on the sagittal image (B) of 0.42, which was shown to be a follicular adenoma on histopathology.
Fig. 8
Fig. 8
SWE showing a nodule with an SWE value of 13.3 kPa on a transverse image (A) and an SWE ratio with the surrounding normal thyroid gland on the transverse image (B) of 0.69, which was shown to be a follicular carcinoma on histopathology. Note the lack of shear wave information from the deeper part of the nodule (arrow) due to the presence of cystic areas.

Fig. 9
Benign lesion with high stiffness on strain elastography: B-mode US image (A) showing a nodule in the left thyroid gland with cystic change in it (arrow). This lesion showed increased stiffness on elastography (B) and the overlay image (color overlayed on B-mode) (C) with predominantly blue color (high stiffness), which was shown to be a fibrotic nodule on histopathology.
