Contrast-enhanced ultrasound (CEUS) is an imaging modality applied in a broad field of medical specialties for diagnostic uses, guidance during biopsy procedures and ablation therapies and sonoporation therapy. Appropriate training and assessment of theoretical and practical competencies are recommended before practicing CEUS, but no validated assessment tools exist. This study was aimed at developing a theoretical multiple-choice question-based test for core CEUS competencies and gathering validity evidence for the test. An expert team developed the test via a Delphi process. The test was administered to medical doctors with varying CEUS experience, and the results were used to evaluate test items, internal-consistency reliability, ability to distinguish between different proficiency levels and to establish a pass/fail score. Validity evidence was gathered according to Messick's framework. The final test with 47 test items could distinguish between operators with and without CEUS experience with acceptable reliability. The pass/fail score led to considerable risk of false positives and negatives. The test may be used as an entry test before learning practical CEUS competencies but is not recommended for certification purposes because of the risk of false positives and negatives.
对比增强超声（CEUS）是一种在广泛的医学专业领域中应用的成像方式，用于诊断、活检程序和消融治疗以及声孔治疗的引导。在进行 CEUS 操作之前，建议进行适当的培训和理论与实践能力评估，但目前还没有经过验证的评估工具。本研究旨在开发一种基于核心 CEUS 能力的理论多选题测试，并为该测试收集有效性证据。一个专家团队通过 Delphi 流程开发了该测试。该测试被应用于具有不同 CEUS 经验的医生，结果用于评估测试项目、内部一致性可靠性、区分不同熟练水平的能力以及建立通过/失败分数。根据 Messick 的框架收集了有效性证据。最终的测试包含 47 个测试项目，能够区分有和没有 CEUS 经验的操作者，具有可接受的可靠性。通过/失败分数导致假阳性和假阴性的风险相当大。该测试可用于学习实际 CEUS 能力之前的入门测试，但不建议用于认证目的，因为存在假阳性和假阴性的风险。
