Application of Ultrasound Combined with CT in Preoperative Diagnosis of Thyroid Cancer

Objective To observe the application value of ultrasound combined with computed tomography(CT)in preoperative diagnosis of thyroid cancer.Methods The study o bjects were 200 patients with thyroid cancer who underwent surgery in the hospital from January 2016 to January 2019.Their ultrasound and CT imaging data were retrospectively analyzed.The lymph node metastasis was recorded.Ta king surgical pathology as controls,the clinical value of ultrasound,CT,and their combination in lymph node metastasis of thyroid cancer was determined.Results Compared with pathology,sensitivity,specificity,accuracy,positive predictive valu e,negative predictive valu e,and Ka ppa value of ult rasound for the diagnosis of lymph node metastasis of thyroid cancer were 84.95%,90.80%,87.50%,92.30%,82.29%,and 0.748,respectively.The above 6 indexes of CT were 90.26%,90.80%,90.50%,92.72%,87.77%,and 0.807,respectively.The above 6 indexes of ultrasound combined with CT were 93.80%.93.10%,93.50%,94.64%,92.04%,a nd 0.867,respectively.The sensitivity,accuracy,positive predictive value and negative predictive value of CT were slightly higher than those of ultrasound(P>0.05).The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of ultrasound combined with CT were higher than ultrasound or CT(P>0.05).Conclusion Both ultrasound and CT can play diagnostic value in preoperative lymph node metastasis of thyroid cancer.The combined application may further improve diagnostic efficiency.
