摘　　要：目的:探讨彩色多普勒超声在亚急性甲状腺炎(SAT)诊断中的应用价值。方法:选取2023年5月—2024年5月宁夏回族自治区人民医院收治的100例疑似SAT患者作为研究对象,患者均进行彩色多普勒超声和磁共振成像(MRI)检查,以临床综合诊断结果作为“金标准”,分析两种检查方式诊断SAT的诊断效能及图像特征。结果:100例受检者经临床综合诊断确诊SAT 88例;彩色多普勒超声检查诊断为阳性84例,阴性16例;MRI诊断为阳性75例,阴性25例。彩色多普勒超声检查诊断SAT的灵敏度、特异度、准确度、阳性预测值和阴性预测值均高于MRI(P<0.05)。SAT患者彩色多普勒超声图像特征:甲状腺实质呈低回声,病灶形态呈现不规则,边缘模糊,边缘成角占90.48%;多数患者回声分布不均匀,病灶部分血流阻力明显增加,血流信号减少,周边血流丰富。SAT患者MRI图像特征:患者病灶均呈现低或稍低信号,T2加权像受累区域呈高信号,伴有水肿,且高信号区域与低信号正常甲状腺组织边界模糊。结论:彩色多普勒超声在SAT诊断中的应用价值较高,其图像特征明显,诊断效能较高,能够为临床诊治工作提供科学依据。Objective:To investigate the value of color Doppler ultrasound in the diagnosis of subacute thyroiditis(SAT).Methods:A total of 100 suspected SAT patients admitted to the People's Hospital of Ningxia Hui Autonomous Region from May 2023 to May 2024 were selected as the study subjects.All patients underwent color Doppler ultrasound and magnetic resonance imaging(MRI).The clinical comprehensive diagnosis results were used as the"gold standard"to analyze the diagnostic efficiency and image features of the two diagnostic methods for the diagnosis of SAT.Results:88 of 100 suspected SAT patients were confirmed positive by clinical comprehensive diagnosis.Color Doppler ultrasonography was positive in 84 cases and negative in 16 cases.MRI diagnosis was positive in 75 cases and negative in 25 cases.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of color Doppler ultrasound were higher than those of MRI(P<0.05).Features of color Doppler ultrasound images of SAT patients:thyroid parenchyma was hypoechoic,lesion shape was irregular,edges blurred,and edge angulation accounted for 90.48%.In most patients,the echo distribution is uneven,the blood flow resistance in the lesion part is obviously increased,the blood flow signal is reduced,and the peripheral blood flow is abundant.Features of MRI images of SAT patients:the lesions of all patients showed low or slightly low signal,the affected area of T2-weighted images showed high signal,accompanied by edema,and the boundary between the high-signal area and the low-signal normal thyroid tissue was blurred.Conclusion:The application value of color Doppler ultrasound in SAT diagnosis is high,its image features are obvious,the diagnostic efficiency is high,and it can provide scientific basis for clinical diagnosis and treatment.
