Abstract:
Objective:To analyze the clinical value of fine needle aspiration biopsy combined with real-time elastography in the diagnosis of thyroid nodules.Methods:From May 2018 to November 2019, 40 patients(58 nodules) with thyroid nodules who underwent fine needle aspiration biopsy and real-time elastography in Heshan People's Hospital were randomly selected, and the results were compared with surgical pathology.Fine needle aspiration biopsy, real-time elastography, and the combined diagnostic value of both were evaluated and the influencing factors were analyzed.Results:Among the 40 cases (58 nodules) of thyroid nodules, 41 nodules (41/58, 70.689%) and 17 nodules (17/58, 29.311%) were benign and malignant.The sensitivity, specificity, positive predictive value, negative predictive value, the area under the ROC curve of fine needle biopsy, real-time elastography outside the joint detection were 88.645%, 86.496%, 88.424%, 85.453% and 0.843, respectively, which were higher than the single index, the differences were statistically significant (χ 2=6.131, 5.164, 5.1427.196, 7.668, all P<0.05). The sensitivity(84.3%, 90.2%), specificity (83.4%, 97.9%) of fine needle biopsy combined with real-time ultrasound elastography in the diagnosis of thyroid nodules without merge calcification or Hashimoto's thyroiditis were significantly higher than those in the diagnosis of merged thyroid nodule calcification or Hashimoto's thyroiditis [sensitivity (80.2%, 84.2%), specificity (75.2%, 96.5%)], the differences were statistically significant (χ 2=3.154, 2.166, all P<0.05). Conclusion:Compared with the individual detection indicators, fine needle aspiration biopsy combined with real-time elastography has higher sensitivity and specificity in the diagnosis of thyroid nodules, and thyroid nodules with/without calcification or Hashimoto's thyroiditis is an important factor affecting diagnosis.
