Study on the Clinical Value of Quantitative Parameters of Ultrasonography Combined with Shear Wave Ultrasound Elastography in the Assessment of Cervical Lymph Node Metastasis in Patients with Thyroid Cancer
Objective:To investigate the clinical value of quantitative ultrasonography parameters combined with shear wave ultrasound elastography in the assessment of cervical lymph node metastasis in patients with thyroid cancer.Methods:80 cases of thyroid cancer patients admitted to the hospital for surgical treatment from January 2020 to February 2022 were selected as the study subjects.Ultrasonography and shear wave ultrasound elastography were performed on the patients 2～3 d before the surgical procedures,and pathologic examination was performed after surgical treatment.The patients were divided into metastasis and no metastasis groups according to their postoperative pathological results,and the quantitative ultrasonography parameters and shear wave ultrasound elastography indices were recorded and the effect of quantitative ultrasonography parameters combined with shear wave ultrasound elastography in evaluating the metastasis of cervical lymph nodes in thyroid cancer patients was analyzed.Results:After postoperative pathological examination,42 out of 80 thyroid cancer patients had lymph node metastasis.The peak intensity values of patients in the metastasis group were higher than those in the no metastasis group,and the difference was statistically significant(t=4.130,P＜0.05).The mean value of Young's modulus,the maximum value of Young's modulus,and the minimum value of Young's modulus of the patients in the metastasis group were higher than those in the no-metastasis group,and the differences were statistically significant(t=14.054,9.253,10.489;P＜0.05).The sensitivity of quantitative parameters of ultrasonography combined with shear wave ultrasound elastography to assess cervical lymph node metastasis in patients with thyroid cancer was 89.8％,and the specificity was 86.0％.Conclusion:Quantitative parameters of ultrasonography combined with shear-wave ultrasound elastography for the assessment of cervical lymph node metastasis in patients with thyroid cancer is definitive and can accurately diagnose cervical lymph node metastasis in patients with thyroid cancer.
