Objective:

To investigate the value of SonoLiver software in contrast-enhanced ultrasound (CEUS) of thyroid tumors.

Methods:

A total of 158 cases of thyroid tumor (88 malignant

70 benign) underwent CEUS. SonoLiver software was used to quantitatively analyze the CEUS and reconstructed dynamic vascular pattern (DVP) parametric images.

Results:

The relative maximum intensity (Imax) of malignant thyroid tumors were significantly higher than that of benign lesions (

P

0.05). The relative rising time (RT)

time to p

eak (TTP) of malignant lesions were shorter than those of benign lesions

and the relative mean transit time (mTT) of malignant lesions was longher than that of benign lesions. The differences were statistically significant (

P

0.05). DVP parametric images of benign and malignant tumors were significantly different. There were 72 malignant lesions (81.8%) filled with confused and irregular or patchy red/yellow

and 59 benign lesions (84.3%) filled with single red/yellow.

Conclusion:

The quantitative parameters and DVP parametric images provided by SonoLiver software are valuable for the diagnosis of thyroid tumors.
