1. How to judge the borders of the nodule in the DORSAL part of the right lobe? *

7 The borders are regular.
3 The borders are blurred.
1 The borders are not regular but the irregularity is caused only by the presence of multiple nodules next to each other. Therefore, the nodule' borders should not be regarded as irregular.
17 It is worth considering the borders as irregular.

Expert comment. I agree with most of the colleagues. Although there are blurred parts of the borders, but the extent of them is lower than 25%. Moreover, it is a reasonable assumption, that in this nodule th blurred is caused by technical reasons.

2. How to judge the borders of the nodule in the VENTRAL part of the right lobe? *

19 The borders are regular.
4 The borders are blurred.
1 The borders are not regular but the irregularity is caused only by the presence of multiple nodules next to each other. Therefore, the nodule' borders should not be regarded as irregular.
4 It is worth considering the borders as irregular.

Expert comment. I can accept the first and third answer. There is quite a large undulation at the ventral

3. What is the echogenicity of the nodule in the VENTRAL part of the lobe?

22 This is an iso/hyperechoic nodule.
5 This is a minimally/moderately hypoechoic nodule
1 This is a deeply hypoechoic nodule.

Expert comment. Although beside the dominant isoechoic parts, the nodule has minimally hypoechoic portions, the degree does not exceed the normal heterogeneity. So, I would consider the lesion as iso/hyperechoic.

4. What is the echogenicity of the nodule in the DORSAL part of the lobe?

2 This is an iso/hyperechoic nodule.
13 This is a minimally/moderately hypoechoic nodule
13 This is a deeply hypoechoic nodule.

Expert comment. When defining the echogenicity, cystic areas sould not take into account. The solid portion are partly minimally/moderately hypoechoic, partly deeply hypoechoic. Th former prevails, so the nodule should be regarded as minimally/moderately hypoechoic.
