【摘要】：目的探讨微血流成像技术(SMI)在甲状腺良恶性鉴别中的应用价值。方法对161个甲状腺结节术前行彩色多普勒超声(CDFI)及SMI检查。结果 CDFI、cSMI和mSMI对甲状腺结节内血流显示率分别为62.7%、67.0%和77.6%,mSMI与CDFI及cSMI间差异有统计学意义(P0.05)。0级血供丰富程度更多见于直径≤1cm的甲状腺恶性病变(P0.05,特异度为90.2%);对于直径1cm的甲状腺结节来说,结节内血供丰富程度在良恶性之间无明显差异(P0.05);Ⅰ、Ⅳ型血供分布模式多见于直径≤1cm的恶性病变(P0.05,特异度分别为90.2%和88.9%),Ⅲ型血供分布模式多见于良性病变(P0.05);微细血管团、中断征及聚集征多见于恶性病变(P0.05,特异度分别为93.1%、91.7%和88.9%)。结论 SMI技术可提高甲状腺结节内血流的显示率,可清晰的显示出甲状腺良、恶性结节性病变内血管的走行及分布特点,对甲状腺结节良、恶性的鉴别有一定的价值。
[Abstract]:Objective to evaluate the value of microflow imaging (SMI) in the differential diagnosis of thyroid benign and malignant. Methods color Doppler ultrasound (CDFI) and SMI examination were performed on 161 thyroid nodules. Results the blood flow rates of CDFI, cSMI and mSMI in thyroid nodules were 62.7%, 67% and 77.6% respectively. There was significant difference between mSMI and CDFI and cSMI (P0.05). The richness of the blood level 0 for more than 1cm in diameter of thyroid malignant lesions (P0.05, 90.2%; specificity) for thyroid nodules with the diameter of 1cm, the blood supply of nodules had no significant difference in abundance between benign and malignant lesions (P0.05); I, IV for blood type distribution pattern is more common in less than 1cm in diameter (P0.05, the specificity were respectively 90.2% and 88.9%), type III blood supply distribution patterns found in benign lesions (P0.05); micro vascular group, interruption syndrome and aggregation sign was seen in malignant lesions (P0.05, specificity were 93.1%, 91.7% and 88.9%). Conclusion SMI technology can improve the display rate of blood flow in thyroid nodules, clearly show the distribution and distribution of blood vessels in benign and malignant thyroid nodules, and is valuable for differentiating benign and malignant thyroid nodules.
