摘　　要：目的探索定量动态增强MRI(dynamic contrast-enhanced magnetic resonance imaging,DCE-MRI)鉴别诊断甲状腺良恶性病变的价值。材料与方法依据病理结果将病例分为良性、恶性及正常组,分析三组之间DCE定量参数值的差异,并进行统计分析。结果共22例患者纳入分析,良性病灶5个,恶性病灶13个,对侧正常对照组织16个,良性与恶性之间,容量转移常数(transfer constant,Ktrans)、速率常数(rate constant,Kep)表现为恶性>良性;血管外细胞外间隙容积比(volume of extravascular extra-cellular space per unit volume of tissue,Ve)表现为良性>恶性,均未见明显统计学差异。结论甲状腺良恶性病灶的DCE定量参数值差异不显著,其具体诊断价值尚需扩大样本量进一步检测。Objective:To explore the diagnosis values of quantitative dynamic contrastenhanced magnetic resonance imaging(DCE-MRI)in thyroid lesions.Materials and Methods:According to the pathological results,the cases were divided into benign,malignant and normal groups.The differences of quantitative parameters of DCE between the three groups were analyzed.Results:A total of 22 patients were included in the analysis,including 5 benign lesions,13 malignant lesions and 16 normal tissues.for transfer constant(Ktrans),rate constant(Kep),the malignant lesions showed higher values than benign lesions,volume of extravascular extra-cellular space per unit volume of tissue(Ve)takes contrary results,but no significant differences was found.Conclusions:There is no significant difference in the quantitative parameters of DCE between benign and malignant thyroid lesions.The specific diagnostic value of DCE needs to expand the sample size for further detection.
