Abstract
Objective: To determine the diagnostic value of papillary thyroid cancer through the combination of thyroid ultrasound elastography and thyroid doppler ultrasound.
Patients and methods: 102 patients (50 patients with benign thyroid nodules and 52 patients with papillary thyroid cancer underwent thyroid doppler ultrasound and thyroid ultrasound elastography from 4/2018 to 7/2020.
Results: In the patients with papillary thyroid cancer, thyroid doppler ultrasound recorded the rate of TIRADS 4 as 5.8% and TIRADS 5 was 94.2% and had a diagnostic value for papillary thyroid cancer. Through thyroid ultrasound elastography, the rate of Rago’s score 4 was 42.3%, Rago‘s score 5 was 40.4% and Rago’s score ≥ 4 was 82.7%. The strain ratio at the cut-off point of 3.92 and the shear wave velocity at the cut-off point of 3.1 m/s had predictive values for papillary thyroid cancer Combining the Rago‘s score 4 with the strain ratio (cut-off point of 3.17), the 2D shear wave velocity (cut-off point of 2.9 m/s) both had a sensitivity of 100.0%. Combining thyroid doppler ultrasound and thyroid ultrasound elastography recorded that when combining TIRADS score‘s 5 with strain ratio (cutoff point 3.8), shear wave velocity (cutoff point 3.05 m/s) had sensitivities of 95.2% and 100.0%, respectively. When combining TIRADS 5 with Rago‘s score ≥ 4, the diagnostic value of thyroid cancer with specificity and positive predictive value both increased to 100%.
Conclusion: Combination of Thyroid ultrasound elastography and Thyroid Doppler ultrasound increases the accuracy in diagnosing papillary thyroid cancer.
