METHODS: The study period was from 2017 to 2023. The institutional database was searched for histologically proven NIFTPs with preoperative ultrasound images. NIFTPs were re-assessed according to the American College of Radiology (ACR), European (EU), and Korean (K) TIRADSs. The indication for biopsy was defined according to TIRADS category-specific size threshold.
RESULTS: Twenty NIFTPs from 19 patients were included. The median size of the NIFTPs was 23 mm. According to ultrasound, 80-85% of NIFTPs were at low-intermediate risk and 5-15% at high risk without significant difference among the tree TIRADSs (p = 0.91). The indication for FNA, according to three TIRADSs, was found in 52-58% of cases with no significant difference among systems (p = 0.96).
CONCLUSIONS: NIFTPs have heterogeneous presentation according to TIRADSs with very low indication rate for FNA.
方法:研究期为2017年至2023年。在机构数据库中搜索经组织学证实的具有术前超声图像的NIFTP。根据美国放射学会(ACR)重新评估NIFTP,欧洲(欧盟),和韩国(K)TIRADS。根据TIRADS类别特异性大小阈值定义活检指征。
结果:纳入19例患者的20个NIFTP。NIFTP的中值尺寸为23mm。根据超声波,80-85%的NIFTP处于低-中等风险,5-15%处于高风险,在树TIRADS之间没有显着差异(p=0.91)。FNA指示,根据三个TIRADS,在52-58%的病例中发现,系统之间没有显着差异(p=0.96)。
结论:根据TIRADS,NIFTP具有异质性表现,FNA适应症率非常低。
