摘要
目的观察甲状腺良恶性结节的三维彩色血管能量成像(3D-CPA)特点,探讨3D-CPA在诊断甲状腺良恶性结节中的价值。资料与方法选择甲状腺结节患者46例,共67个结节,术前行3D-CPA超声检查,依据术后病理结果将结节划分为结节性甲状腺肿、甲状腺腺瘤和甲状腺癌3组,分析良恶性结节的血流分布、走行规律及其周围腺体的血供情况。结果 46例患者中,良性37例,包括结节性甲状腺肿33例共48个结节,甲状腺腺瘤4例共6个结节,恶性9例共13个结节。3D-CPA显示良性结节血流分布以外周为主,走行自然,周围腺体血供相对不多,结节性甲状腺肿均未构成球形网状结构;甲状腺腺瘤瘤体血流灌注呈球形网状结构。恶性结节血管明显增粗,走行扭曲,且粗大杂乱,血运分布以内部为主。结论 3D-CPA可直观地显示甲状腺良恶性结节的立体形态、与周围组织的关系及血管的分布特点,有助于提高甲状腺良恶性结节的诊断水平,对其鉴别诊断具有一定价值。
Purpose To evaluate the application of three-dimensional color power angiography （3D-CPA） in the diagnosis of benign and malignant thyroid nodules. Materials and Methods Sixty-seven thyroid nodules in 46 patients were examined with 3D-CPA before operation. All the nodules were divided into three groups including nodular goiters, thyroid adenomas and thyroid cancers according to pathological results. The blood distribution, the traveling course, and the difference of the blood supply around glands of benign and malignant nodules were analyzed. Re, suits In 46 patients, 37 cases were diagnosed as benign and 9 cases （13 nodules） as malignant. There were 33 cases of nodular goiters with 48 thyroid nodules, and 4 cases of thyroid adenoma with 6 nodules. In benign nodules, the blood vessels were commonly surrounding the mass withnatural course, and relatively small blood supply. The perfusion of thyroid adenoma was bulb-shaped with reticulation, which was not seen in nodular goiter. Malignant nodules demonstrated dilated, distorted and irregular blood vessel distribution, which was more abundant in the mass. Conclusion 3D-CPA can visually demonstrate the solid shape, relationship with adjacent tissue, and the vascularity of benign and malignant thyroid nodules, and is beneficial to differential diagnosis.
