摘要
目的探讨CT、磁共振(MRI)检查对甲状腺结节(TN)性质的鉴别诊断价值。方法回顾分析2018年1月至2019年5月于我院就诊治疗的84例TN患者的临床、影像学资料,比较不同检查方法对TN的诊断情况及其影像学特征。结果CT与MRI检查在良性甲状腺结节中的诊断符合率比较无统计学意义(P>0.05),但对于恶性甲状腺疾病的诊断符合率CT检查显著高于MRI检查(P<0.05)。CT检查中良、恶性病灶均可表现为密度不均的低密度结节,恶性可伴有坏死区,且良性CT增强病灶可见中度强化,分界清楚,而恶性存在钙化结节。MRI良性病灶为圆形或椭圆形病灶,部分病灶边界清晰、规整且分界清楚,T1WI上为等信号或稍低信号,T2WI上为高信号,恶性病灶表现为不规则或分叶状病灶,边界模糊,分界不清,两者肿大淋巴结均可表现T2WI高信号。结论CT和MRI对甲状腺良、恶性疾病灶的诊断均具有较好的诊断准确性,均可较好地显示良、恶性病灶的组织和形态结构,二者各有优势,若临床将二者联合使用其临床价值更有优势。
Objective To explore the differential diagnosis value of CT and magnetic resonance imaging(MRI)for the nature of thyroidnodular(TN).Methods The clinical and imaging data of 84 patients with TN who were treated in our hospital from January 2018 to May 2019 were retrospectively analyzed.The diagnosis of different examination for TN and its imaging features were compared.Results There was no significant difference in the diagnostic accuracy between CT and MRI for benign thyroidnodular(P>0.05),but the accuracy of CT examination for malignant thyroid disease was significantly higher than that of MRI(P<0.05).In the CT examination,both benign and malignant lesions can be characterized by low-density nodules with irregular shaped and uneven density,malignant lesions may be associated with necrotic areas,and benign CT-enhanced lesions can show moderate enhancement with clear boundaries and malignant CT-enhanced lesions can show calcified nodules.MRI benign lesions are round or elliptical.The borders of some lesions are clear,regular and well-defined.T1WI shows equal or slightly lower signal,T2WI shows high signal,malignant lesions are irregular or lobulated.borders are blurred,and the boundaries are unclear.The swollen lymph nodes of them can show high T2WI signals.Conclusion CT and MRI have good accuracy in the diagnosis of benign and malignant thyroid lesions,and can better display the tissue and morphological structure of benign and malignant lesions.both they have their own advantages,and if they are used in combination,their clinical value is more advantageous.
