Abstract

Abstract: The relationship between blood flow distribution pattern, lesion volume and benign and malignant diagnosis of thyroid nodules and patient efficacy prediction was analyzed by SMI technique. 60 patients with thyroid nodules admitted to our hospital from January 2017 to February 2019 were divided into benign group and malignant group according to the postoperative pathological results. Microwave ablation was used to treat patients and SMI was used before and after treatment. And CEUS technology was used to assess the patient's condition. The results showed that the sensitivity, specificity, accuracy and AUC of the patients were significantly higher than those of CEUS by SMI, and the difference was statistically significant (P<0.05). The lesions were not completely ablated and participated by SMI scan. The microvessel rate was significantly higher than that of CEUS, and the difference was statistically significant (P<0.05). The size, the length and the width of the lesion by SMI scan were significantly higher than those of the CEUS scan, and the difference was statistically significant(P<0.05). The results show that SMI technology has a high application value in the diagnosis of benign and malignant thyroid nodules, and can be effectively used to evaluate the clinical efficacy of patients.

Key words: superb microvascular imaging (SMI), blood flow distribution pattern, volume of lesions, thyroid nodules, benign and malignant, contrast-enhanced ultrasound(CEUS)
