摘要
目的:探讨彩色多普勒在甲状腺单发结节良恶性诊断与鉴别诊断中的价值。方法:对经手术及病理证实的74例甲状腺单发结节的二维及彩色多普勒声像图进行比较分析。结果:74例中良性53例,恶性21例。恶性病灶表现为:低回声,边界模糊,形态不规整,周边无声晕,内可见微小钙化,血流信号丰富。良性病灶表现为:边界规则并可见声晕,内部回声相对均质,少有沙砾样钙化。病灶内部血流较少。结论:彩色多普勒超声在甲状腺单发结节良恶性诊断与鉴别诊断中有重要价值。
Objective： To investigate the effectiveness of color Doppler flow imaging （CDFI） in differentiation of malignant and benign thyroid solitary nodules. Methods：The two-dimensional and color Doppler ultrasound images of 74 cases of solitary thyroid nodules, which were all pathologically confirmed, were analyzed and compared. Results： On histology,53 cases were diagnosed as benign and 21 cases as malignant. Malignant nodules were more often ill defined, hypoechogenic, irregular, absent of halo sign and contain microcalcification and rich blood flow signals in the lesions. Benign nodules were regular and homogeneous echo, rarely with gravel calcification. There were poor blood flow signals. Conclusion：Color Doppler ultrasound is valuable in the differential diagnosis of malignant and benign nodule of solitarythyroid nodules.
