摘要
采用ＨＤＩ３０００超宽频全数字彩色声像仪检查了９１例甲状腺结节性病变的彩色多普勒血流图及多普勒频谱，同时与病变的核素扫描结果对比分析。结果显示结节内ＲＩ＞０．７有助于良恶性的鉴别，其敏感性为７３．７％，特异性为９２．８％，准确性为８９％；峰值流速及血流信号的丰富与否对良恶性无鉴别意义；血流丰富的凉结节或冷结节多提示腺瘤或癌。初步发现恶性肿瘤血流信号的多少似乎与肿瘤的组织类型有关。
Using ATL HDI 3000 digital color ultrasound modality with L10 5 MHz broadband scanhead we investigated color duplex sonography of 91 consecutive patients with thyroid nodular lesions.The appearance of the thyroid lesions with color Doppler was also compared with nuclear scintigraphy.Results showed that in Doppler parameters a resistance index(RI)was helpful in differentiation malignant from benign.RI>0.7 would give the best discrimination with a sensitivity of 73.7%,a specificity of 92.8%,an accuracy of 89%.Peak flow velocity and color Doppler signals had no differential significance between two groups.The simultaneous presence of hypocapture at scintigraphy and abundant color signals in a nodule was highly suggestive of thyroid neoplasm.It seemed that level of color signals have some relation with certain tissue type of malignant tumors.
