摘　　要：目的：探讨磁共振弥散加权成像（DWI）与动态增强扫描（DCE-MRI）在甲状腺良、恶性结节的鉴别诊断价值。方法术前分别对123例甲状腺结节病变患者（共169个病灶）行MR常规平扫及动态增强扫描（DCE-MRI）、DWI（b值为150、300、500s/mm^2）检查，观察各组常规、DWI图的信号表现，测量病灶的表观扩散系数（ADC）值，绘制及比较TIC曲线，作出诊断，最后与病理对照分析。结果平扫T1WI良性结节呈等或略低信号，恶性结节多呈不均匀稍低或等信号；Objective To investigate the magnetic resonance diffusion weighted imaging（DWI）and dynamic enhanced scan （DCE）MRI value in the differential diagnosis of benign and malignant thyroid nodules. Methods 123 cases of thyroid nodule lesions, a total of 169 lesions,49 cases of men,women,74 cases. By 1.5 T MR routine scan and dynamic enhanced scan（DCE）MRI,DWI （b value is 150,300,500s/mm^2）were divided into examination group and observation group routine,DWI figure signal,can measure the lesion of the apparent diffusion coefficient（ADC）value,and comparison of TIC curve drawing. According to the combined diagnosis and pathology. Results The scan T1WI benign nodules are isointense or slightly low signal,such as malignant nodules more uneven slightly low or equal signal;T2^＊
