Abstract

Objective: To describe some imaging characteristics of ultrasound elastography (UE) and determine the value of tissue UE in diagnosing thyroid nodules. Subjects and Methods: This cross-sectional descriptive study was conducted on 46 patients at Can Tho University of Medicine and Pharmacy Hospital and Can Tho Central General Hospital. Patients underwent 2D ultrasound to detect thyroid nodules and then had tissue elastography ultrasound (UE) performed, with pathological or cytological results of thyroid nodules available. Results: The average age of the patients was 49.65 ± 12.97 years, with the disease being more common in females than males at a ratio of 93.3%. The Tsukuba scoring system for UE images showed a majority at score 3 with a rate of 39.1% (18/46). Malignant thyroid nodules according to the Tsukuba score of 4 and 5 accounted for 55%, while scores of 1, 2, and 3 accounted for 3.8% (p < 0.01), with a sensitivity of 91.66%, specificity of 73.52%, positive predictive value of 55%, negative predictive value of 96.15%, and accuracy of 78.26%. For malignant thyroid nodules as determined by fine-needle aspiration (FNA), malignant UE results were 75%, higher than benign at 8.8% (p < 0.01), with a sensitivity of 75%, specificity of 91.17%, positive predictive value of 75%, negative predictive value of 91.17%, and accuracy of 86.95%. Conclusion: Cryotherapy is a simple, effective treatment method for cervical lesions, with few complications and a high satisfaction rate.
