概括
美国放射学学院甲状腺成像报告和数据系统 (ACR TIRADS) 的分类可以帮助在PET/CT扫描上检测到的偶然甲状腺结节的风险分层. 低TIRADS评分 (1或2) 或没有可疑特征的结节具有0%的恶性瘤风险,可能不需要精细针吸收 (FNA).
科学领域:
- 核医学是一种核医学.
- 放射学 放射学是一门学科.
- 内分泌学 在内分泌学.
背景情况:
- pozitron发射断层扫描/计算机断层扫描 (PET/CT) 扫描越来越多地检测出偶然的甲状腺结节.
- 2-[18F]--2-脱氧-d-葡萄糖 (FDG) 激发性结节带有恶性瘤的高风险,需要进一步调查.
- 有限的研究存在于FDG-avid甲状腺偶发性瘤的风险分层.
研究的目的:
- 评估美国放射学学院 (ACR) 甲状腺成像报告和数据系统 (TIRADS) 风险分层分类的有效性.
- 评估在偶然检测到的FDG-avid甲状腺结节中需要精细针吸入细胞学 (FNA).
主要方法:
- 过去10年来FDG-avid甲状腺偶发性瘤的回顾性数据收集.
- 使用ACR TIRADS分类来表征结节.
- 进行细针吸入细胞学 (FNAC),结果使用贝塞斯达系统进行分类 (不包括非诊断样本).
主要成果:
- 恶性瘤的发病率为低风险瘤的36%,高风险瘤的45% (P=0.516).
- 对恶性瘤检测的ACR TIRADS灵敏度和特异性分别为56%和54%.
- 在TIRADS 1或2类别中没有发现恶性结节;缺乏可疑的超声波特征具有1.0负预测值.
结论:
- 被归类为TIRADS 1或2的FDG-avid结节或缺乏可疑超声波特征的结节,恶性瘤发生率为0%,可能不需要FNA.
- 由于高恶性瘤风险和TIRADS系统的敏感性有限,被归类为TIRADS 3或更高的FDG-avid结节保证了FNA.
