SMI技术测定血流分布模式、消融灶体积与甲状腺结节良恶性诊断及患者疗效预测的关系研究

分析SMI（微血管成像技术）测定血流分布模式、消融灶体积与甲状腺结节良恶性诊断及患者疗效预测的关系。将我院2017年1月～2019年2月期间收治的60例甲状腺结节患者依照患者术后病理检测结果分为良性组及恶性组；采用微波消融术对患者进行治疗，并在治疗前后采用SMI及CEUS（超声造影）对患者病情进行评估。结果显示，采用SMI对患者进行评估的敏感度、特异度、准确度及AUC，均明显高于CEUS，且差异存统计学意义（P<0.05）；采用SMI扫描检查的病灶未完全消融率、参与微血管率均明显高于CEUS检查，且差异存统计学意义（P<0.05），采用SMI扫描检查的消融灶体积、消融灶长及消融灶宽均明显高于CEUS扫描检查，且差异存统计学意义（P<0.05）。证明采用SMI技术对甲状腺结节良恶性进行诊断具有较高的应用价值，并可有效用于评估临床疗效。

Study on the Relationship Between Blood Flow Distribution Pattern,Lesion Volume and Benign and Malignant Diagnosis of Thyroid Nodules and Patient’s Efficacy Prediction by SMI Technique

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.
