ACR TI-RADS危险分级结合多模态超声影像技术对甲状腺良恶性病变的诊断价值

Diagnostic value of ACR TI-RADS risk grading combined with multimodal ultrasonography in benign and malignant thyroid lesions

摘要

摘要:
目的探讨美国放射学会（ACR）甲状腺TI-RADS风险分层与多模态超声对甲状腺病变的诊断价值。
方法对61例病人进行超微血管（SMI）及剪切波弹性成像扫查（SWE）。最终根据手术获取的病理报告将结节分成良性和恶性组，比较TI-RADS风险分层及定量评分，并对2组的SMI血流分类和SWE弹性参数进行检测并分析。
结果2组TI-RADS均分为2~5类，危险分级差异有统计学意义（P＜0.01）；恶性组量化评分高于良性组（P＜0.01）。2组SMI血流分级、SWE弹性参数比较差异均有统计学意义（P＜0.01）。联合诊断恶性结节的敏感性、特异性均强于单独诊断。
结论ACR TI-RADS风险分层、SMI和SWE单独诊断甲状腺病变均有价值，联合诊断的效能显著提高。

Abstract:
ObjectiveTo analyze diagnostic value of American College of radiology thyroid imaging reporting and data system(ACR TI-RADS) risk grading combined with multimodal ultrasonography in benign and malignant thyroid lesions.
MethodsSixty-one patients were detected using superb microvascular imaging(SMI) and shear wave elastography(SWE), and divided into benign group and malignant group according to the pathological results.The ACR TI-RADS risk grading and quantitative scoring in two groups were implemented, and the SMI blood flow grading and SWE elastic parameters in two groups were detected and analyzed.
ResultsThe ACR TI-RADS risk grading in two groups were divided into 2-5 classes, and the difference of risk grading was statistically significant(P < 0.01).The quantitative scores in malignant group were higher than those in benign group(P < 0.01).The differences of the SMI blood flow grading and SWE elastic parameters between two groups were statistically significant(P < 0.01).The sensitivity and specificity of combined diagnosis of malignant nodules were better than that of single diagnosis.
ConclusionsThe risk stratification of ACR TI-RADS, SMI and SWE are all valuable in the diagnosis of thyroid lesions alone, and the efficacy of combined diagnosis can be significantly improved.
