DISTRIBUTION OF ANSWERS
1. How to judge the intranodular echogenic figures in the largest discrete lesion of the LEFT lobe?
These figures are microcalcifications. 3
These figures are comet-tail artifacts.
Both comet-tail artifacts and microcalcifications are present. 2
2. What is the echogenicity of the largest lesion in the LEFT lobe?
This is an iso/hyperechoic nodule.
This is minimally/moderately hypoechoic nodule. 1
This is deeply hypoechoic nodule.
This is a heterogeneous nodule composed of minimally/moderately and deeply hypoechoic parts. 4
3. How to classify the largest lesion in the LEFT lobe according to the EU-TIRADS?
Category 2 (benign)
Category 3 (low risk)
Category 4 (intermediate risk) 1
Category 5 (high risk) 4
4. According to the EU-TIRADS, should the largest nodule in the RIGHT lobe be evaluated by FNA?
Yes. 2
No. 3
6. Which statement is correct regarding the RIGHT lobe?
The lobe has multiple nodules of different echogenicities.
The lobe both pathological nodules and discrete lesions of Hashimoto's thyroiditis. 3
The discrete lesions are either more active foci of Hashimoto's thyroiditis or areas less influenced by the underlying thyroiditis. 2
