摘　　要：目的探讨实时超声造影增强模式对良、恶性甲状腺单发结节的鉴别诊断价值。方法 78例甲状腺单发结节患者(恶性37例、良性41例)均接受超声造影检查,观察造影增强模式,并从以下6方面进行评价:①增强程度;②增强方式;③是否均匀增强;④是否完全增强;⑤增强时病灶边界是否清晰;⑥增强时病灶形态是否规则。结果除增强方式外,甲状腺良、恶性结节的其他增强模式差异均有统计学意义(P均<0.05)。恶性病灶增强时形态多不规则(94.59%),边界不清(86.49%),无明显增强(78.38%),恶性病灶中不均匀增强、不完全增强的病灶占多数,分别为78.38%和70.27%。结论甲状腺良、恶性结节超声造影增强模式存在显著差异,具有重要的临床意义。Objective To study the enhanced patterns of solitary thyroid nodule with real-time contrast-enhanced ultrasound and assess its value in differentiating between malignant and benign thyroid nodules.Methods Seventy-eight patients with solitary thyroid nodule（37 malignant,41 benign）underwent real-time contrast-enhanced ultrasound.The patterns of their enhancement were assessed from six aspects：Degree of enhancement,process of enhancement,homogeneity of enhancement,completeness of enhancement,boundary of the enhanced lesions,shape of the enhanced lesions.Results Contrast-enhanced patterns were significantly different between benign and malignant thyroid nodules（all P0.05）,except for process of enhancement.The shape of most malignant lesions was irregular（94.59%）,the boundary was unclear（86.49%）and had no significantly enhanced（78.38%）.Most malignant lesions were inhomogeneously（78.38%）and incompletely enhanced（70.27%）.Conclusion The patterns of real-time contrast-enhanced ultrasonography are significantly different between benign and malignant thyroid nodules,and have important clinical value.
