Value of thyroid nodule ultrasonic strain elastography quantitative analysis in judging benignancy or malignancy of nodules

摘要

Objective:To analyze the value of thyroid nodule ultrasonic strain elastography quantitative analysis in judging benignancy or malignancy of nodules.Methods: Patients diagnosed with thyroid nodule and receiving ultrasonic strain elastography quantitative analysis in our hospital were selected for study and divided into benign group and malignant group according to fine needle biopsy or the pathological results after surgical resection; mean strain values of quantitative indicators, blue region area and disorder of ultrasonic strain elastography, expression levels of malignant biological molecules in nodule tissue as well as the contents of serum tumor markers were detected.Results:Mean strain value of malignant group was lower than that of benign group, blue region area and disorder were higher than those of benign group, and standard deviation, complexity, kurtosis, skewness, contrast, equality, consistency and correlation were without significant differences; mRNA contents ofFascin-1, S100A4, STAT3, TC-1, MUC1 andMUC15 in thyroid nodules as well as serum Midkine, Galectin-3, CEACAM1 and TFF3 contents of malignant group were significantly higher than those of benign group, negatively correlated with mean strain value and positively correlated with blue region area and disorder.Conclusions:Mean strain values of quantitative indicators, blue region area and disorder of thyroid nodule ultrasonic strain elastography can judge benign or malignant nodules and assess the malignant degree.
