Abstract

Objectives: To evaluate the effects and benefits of training radiology residents on contrast-enhanced ultrasound (CEUS) according to the Liver Imaging Reporting and Data System (LI-RADS).

Methods: In total, 234 patients at high risk of hepatocellular carcinoma (HCC) who underwent CEUS were enrolled, including 27 lesions in the education set and 207 lesions in the test sets (a-d). Forty-five radiology residents and 4 radiology experts involved in CEUS LI-RADS training individually reviewed the test sets before, immediately after, and 3-months after training. The consistency with kappa values of the description of CEUS features, the classification of focal liver lesions (FLLs), and the diagnostic performance were evaluated.

Results: The level of agreement between the radiology experts and residents improved after training (all p < 0.05), while there were no significant differences between the post-training and 3-months post-training results (all p > 0.05). The sensitivity, specificity, positive predictive value, and area under the curve (AUC) based on the CEUS LI-RADS classification of the radiology experts in the diagnosis of HCC were 62.9%, 96.4%, 96.3%, and 0.796, respectively. The diagnostic performance of the radiology residents significantly improved after training (all p < 0.05). Misunderstanding of definitions and subjective interpretation of images were the main reasons for disagreement with multiple responses.

Conclusion: Dedicated CEUS LI-RADS training improved the performance of radiology residents in diagnosing FLLs and their agreement with radiology experts on CEUS features. Images and videos to explain typical features of the training were essential to improve agreement between the radiology experts and residents.

Critical relevance statement: Agreement on lesion descriptors between radiology experts and residents can improve with training.

Key points: The diagnostic performance of less experienced radiologists for diagnosing HCC could be improved by training. Images and videos to explain typical features during training were essential. Agreement on lesion descriptors between radiology experts and residents improved after training.

对放射科住院医生进行造影剂增强超声 LI-RADS 分类培训：培训后表现的回顾性比较。

目的评估根据肝脏成像报告和数据系统（LI-RADS）对放射科住院医师进行对比增强超声（CEUS）培训的效果和益处：共234例接受CEUS检查的肝细胞癌（HCC）高风险患者，其中27例病变为教育集，207例病变为测试集（a-d）。45 名放射科住院医师和 4 名参与 CEUS LI-RADS 培训的放射科专家分别在培训前、培训后和培训 3 个月后对测试集进行了审查。对 CEUS 特征描述、局灶性肝脏病变 (FLL) 分类和诊断结果的一致性进行了 kappa 值评估：结果：培训后，放射科专家与住院医师之间的一致性水平有所提高（均为 P 0.05）。根据 CEUS LI-RADS 分级，放射科专家诊断 HCC 的敏感性、特异性、阳性预测值和曲线下面积（AUC）分别为 62.9%、96.4%、96.3% 和 0.796。经过培训后，放射科住院医师的诊断能力明显提高（均为 p 结论：放射科住院医师的诊断能力明显提高：专门的 CEUS LI-RADS 培训提高了放射科住院医师诊断 FLL 的能力以及他们与放射科专家在 CEUS 特征上的一致性。培训中解释典型特征的图像和视频对于提高放射科专家和住院医师之间的一致性至关重要：关键相关性声明：放射学专家和住院医师在病变描述上的一致性可以通过培训得到改善：要点：经验不足的放射科医师诊断 HCC 的能力可通过培训得到提高。在培训过程中解释典型特征的图片和视频至关重要。培训后，放射科专家和住院医师在病灶描述上的一致性有所提高。

期刊介绍： Insights into Imaging (I³) is a peer-reviewed open access journal published under the brand SpringerOpen. All content published in the journal is freely available online to anyone, anywhere! I³ continuously updates scientific knowledge and progress in best-practice standards in radiology through the publication of original articles and state-of-the-art reviews and opinions, along with recommendations and statements from the leading radiological societies in Europe. Founded by the European Society of Radiology (ESR), I³ creates a platform for educational material, guidelines and recommendations, and a forum for topics of controversy. A balanced combination of review articles, original papers, short communications from European radiological congresses and information on society matters makes I³ an indispensable source for current information in this field.
