Caption: In comparison with malignant nodules, ,   .
The distribution of VTI score (score 1 to score 6) of benign nodules was significant different from that of the malignant ones. Most of benign nodules were classified to be score 1 to score 3 on VTI score and most of malignant nodules were classified to be score 4 to score 6 ( , ). But the distribution of VTI score of nodular goiters was not significantly different from that of Hashimoto nodules ( , ).
