Abstract：Objective To investigate the application value of vascular caliber in identifying the benign
and malignant thyroid nodules by superb microvascular imaging (SMI) technology. Methods Totally
105 patients with 111 thyroid nodules were randomly selected by ultrasonography, which were divided
into benign group and maligant group according to pathological detection results. Then benign group and
maligant group were divided into two groups respectively according to the size of the nodules, and the
grouped criterion was 2 cm. SMI software was used to measure the blood vessel diameters in the thyroid
nodules, and compared the results. Results In the group which the value of vascular caliber was less than
or equal to 2 cm, the average blood vessel diameters of benign group and maligant group were separately
(0.90±0.13), (0.61±0.17) mm, so there were significant statistical differences between the two groups
(P=0.000), the diagnostic threshold was 0.75 mm, the sensitivity was 77%, the specificity was 85%.
In the group which the value of vascular caliber was larger than 2 cm, the corresponding values were
separately (1.12±0.19), (0.76±0.20) mm, there were also significant statistical differences between
two groups (P=0.000), the diagnostic threshold was 0.95 mm, the sensitivity was 76%, the specificity
was 83%. Conclusion SMI can effectively measure the diameter of blood vessels, which is conducive to
diagnose the benign and malignant thyroid nodules.
