Echocardiographers can detect abnormalities accurately and rapidly from dynamic images. This is likely due to the application of cue-based associations resident in memory, a process known as cue utilization. This study investigated whether cue utilization is associated with the ability to apply within-domain capabilities (dynamic) to more degraded images (static). Fifty-eight echocardiographers completed the echocardiography edition of the Expert Intensive Skills Evaluation 2.0 (EXPERTise 2.0) to establish behavioral indicators of within-domain cue utilization. They also completed an abnormality detection and categorization task that comprised briefly presented static and moving images (50% abnormal). Behaviors consistent with higher cue utilization were associated with greater accuracy in detecting both static and dynamic images but not for categorization. This study provides important information about how experts who have the capacity to utilize cue-based strategies can rapidly and accurately detect abnormalities from domain-specific stimuli and generalize their skills to more challenging stimuli.

静态与动态医学图像：线索利用在诊断性能中的作用

超声心动图可以从动态图像中准确快速地检测异常。这可能是由于在记忆中应用了基于线索的关联，这一过程被称为线索利用。这项研究调查了线索利用是否与将域内功能（动态）应用于更退化的图像（静态）的能力相关。58 名超声心动图技师完成了专家强化技能评估 2.0 (EXPERTise 2.0) 的超声心动图版，以建立领域内线索利用的行为指标。他们还完成了一项异常检测和分类任务，其中包括简要呈现的静态和动态图像（50% 异常）。与较高线索利用率一致的行为与检测静态和动态图像的准确性更高有关，但与分类无关。这项研究提供了关于有能力利用基于线索的策略的专家如何快速准确地检测特定领域刺激的异常并将他们的技能推广到更具挑战性的刺激的重要信息。
