目的通过对桥本甲状腺炎的超声二维图象及彩色多普勒血流显像(CDFI)分析,提高诊断符合率。方法应用二维超声观察甲状腺及病灶的大小、形态、边界、内部回声以及CDFI观察腺体内及病灶区的血流分布。结果超声显示52例桥本甲状腺炎均有甲状腺弥漫性非均匀性肿大,回声不均,38例检出有结节,且结节形态不规则,边界不清,无包膜,内部多为均匀低回声,CDFI显示腺体内血流无明显改变,结节周边血流低或无。超声诊断符合率为69.2%。结论利用高频探头和彩色多普勒技术,可提高对桥本甲状腺炎超声诊断的敏感性。
Objective To improve the diagnostic coincidence rate by using two-dimensional ultrasound images and color Doppler flow imaging (CDFI) analysis of Hashimoto’s thyroiditis. Methods The size, shape, boundary, internal echo and CDFI of thyroid gland and lesion were observed by two-dimensional ultrasonography to observe the distribution of blood flow in the gland and lesion area. Results Ultrasound showed that diffuse heterogeneity of thyroid in 52 cases of Hashimoto’s thyroiditis was enlarged and the echoes were not uniform. The nodules were found in 38 cases, the nodules were irregular in shape, the boundary was unclear, Uniform hypoechoic, CDFI showed no significant changes in the glandular blood flow, peripheral nodules, low or no blood flow. The coincidence rate of ultrasonic diagnosis was 69.2%. Conclusion The use of high-frequency probe and color Doppler ultrasound technology can enhance the sensitivity of Hashimoto’s thyroiditis ultrasound diagnosis.
