高频超声联合PSV、RI、Adler血流分级在甲状腺良恶性结节中的诊断价值

本研究探讨高频超声联合彩色多普勒超声参数在诊断甲状腺良恶性结节中的价值。选取40例甲状腺癌患者作为观察组,42例甲状腺良性结节患者作为对照组,比较两组、不同N和T分期患者高频超声联合彩色多普勒超声参数,并对数据进行统计分析。两组结节形态、边界、回声、钙化超声征象比较,差异具有统计学意义(P<0.05)。观察组A/T_C、A/T_L、TI-RADS分级评分、PSV、RI、Adler血流分级评分高于对照组(P<0.05)。各参数联合诊断恶性甲状腺结节的AUC为0.902,诊断N1分期的AUC为0.879,诊断Ⅲ+Ⅳ分期的AUC为0.915,均大于任一单一参数(P<0.05)。可见采用高频超声、彩色多普勒超声联合观测甲状腺结节征象与A/T_C、A/T_L、TI-RADS分级、PSV、RI、Adler分级,可诊断结节性质,并能评估恶性结节患者术前肿瘤分期,为临床治疗、决策提供量化参考。

Diagnostic Value of High-frequency Ultrasound Combined with PSV,RI and Adler Blood Flow Classification in Benign and Malignant Thyroid Nodules

The value of high-frequency ultrasound combined with color Doppler ultrasound parameters in the diagnosis of benign and malignant thyroid nodules was explored.Forty patients with thyroid cancer were selected as the observation group and 42 patients with benign thyroid nodules were selected as the control group.The parameters of high-frequency ultrasound combined with color Doppler ultrasound in patients with different N and T stages were compared between the two groups,and the data were statistically analyzed.The comparison of nodule morphology,boundary,echo and calcification ultrasound signs between the two groups was statistically significant(P<0.05).The A/T_C,A/T_L,TI-RADS classification scores,PSV,RI,and Adler blood flow classification scores of the observation group were higher than those of the control group(P<0.05).The AUC of each parameter combined diagnosis of malignant thyroid nodules was 0.902.The AUC of diagnosis N1 staging was 0.879,and the AUC of diagnosisⅢ+Ⅳstaging was 0.915.All of which were greater than any single parameter(P<0.05).It can be seen that the combination of high-frequency ultrasound and color Doppler ultrasound to observe the signs of thyroid nodules and A/T_C,A/T_L,TI-RADS grades,PSV,RI,and Adler grades can diagnose the nature of nodules.It can also assess the preoperative tumor stage of patients with malignant nodules,and provide a quantitative reference for clinical treatment and decision-making.
