| Objective:To investigate the application value of conventional high frequency ultrasound and ultrasound elastography
in the identification of benign and malignant thyroid nodules.Methods:120 inpatients with thyroid nodular disease (146 thyroid nodules)
were selected. The patients were examined by conventional high frequency ultrasound and ultrasound elastography. The sensitivity,
specificity and accuracy of different methods on the diagnosis of benign and malignant thyroid nodules were calculated, with
postoperative pathologic examination as the gold standard.Results:146 nodules were confirmed by surgery pathology examination in
120 patients, including 98 benign nodules, 48 malignant nodules. Conventional high frequency ultrasound showed that the difference on
the shape, border, coated, internal echo, micro calcification and RI values between the benign nodules and malignant nodules was
statistically significant (P< 0.05). Comparing the diagnostic efficiency of conventional high frequency ultrasonography with ultrasound
elastography, there was no statistical significance (P > 0.05); Comparing the sensitivity(X2= 12.22, P < 0.01), specificity(X2 = 10.21, P <
0.01) and accuracy (X2 = 9.31, P< 0.01) of conventional high frequency ultrasonography with combined ultrasonic diagnosis, there were
statistically significant differences; Comparing the sensitivity(X2= 6.51, P < 0.01), specificity(X2= 5.82, P< 0.05) and accuracy(X2= 4.56,
P < 0.05) of ultrasound elastography with combined ultrasonic diagnosis, the differences were statistically significant.Conclusion:The
identification of conventional high frequency ultrasonography combined with ultrasonic elastography in the diagnosis of benign and
malignant thyroid nodule had high sensitivity and accuracy, worthy of further promotion of clinical application. |
