高频超声显像与彩色多普勒血流显像对甲状腺癌的诊断价值

Diagnosis Value of High-frequency Ultrasonography and Colour Doppler Flow Imaging on Thyroid Carcinoma

目的探讨高频超声显像和彩色多普勒血流显像对甲状腺癌的诊断价值。方法对118例经手术病理证实为甲状腺癌病人的声像图和彩色多普勒表现进行回顾性分析,并与甲状腺腺瘤和结节性甲状腺肿的超声表现进行对照。结果甲状腺癌多数为单发(72.9%)、实质性(79.7%)、低和中等回声的(86.2%)甲状腺结节;内部回声均匀占25.4%,不均匀占62.9%;边界不规整占88.1%,规整11.9%;少数结节伴有液化、钙化或声晕。结论高频超声显像能早期发现癌性甲状腺结节,使甲状腺癌获得早期诊断;对良性肿瘤的判断,具有一定的临床价值。

Objective To explore the value of high-frequency ultrasonography and eolour Doppler flow imaging on thyroid carcinoma. Methods Uhrasonograms of 118 thyroid carcinoma patients who had been confirmed by postoperatively pathological examination were analyzed retrospectively, and were compared with that of those with thyroid adenoma and nodular goiter. Results The major sonographic appearance of thyroid carcinoma was single （72.9%）, solid （ 79.7% ）, lowly or medially echoic （ 86.2% ）. About 25.4% of the carcinous thyroid nodes showed homogeneous echo, and 62.9% showed unhomogeneous echo. Furthermore, 88.1% showed irregular borders and 11.9% showed regular borders. Several nodes were accompanied by liquefaction, calcification or acoustic halos. Conclusion High-frequency ultrasonography can find carcinous nodes early, and make thyroid carcinoma early diagnosed. It may be of value on identification of benign and malignant thyroid tumors in clinical practice.
