Conventional ultrasound (US) is time-consuming, and results are subjected to high interobserver variability. In this study, the reliability of a novel thyroid US cine loop standard operating procedure (SOP) applied by non-physicians (Medical Technical Assistant, MTA) is investigated. Thirty-three consecutive patients (22 females, 11 males) were enrolled. Patients underwent conventional thyroid US performed by a nuclear medicine physician and additional MTA US cine loop according to a local SOP that includes transversal and sagittal cine loops covering the entire thyroid. The video sequences were transferred to the Picture Archiving and Communication System (PACS) for second reading purposes. MTA US data were not considered for medical reports but for blinded second reading review of the PACS images. The results of conventional physician US reports and reviewed MTA US cine loops were compared regarding size determinations of the thyroid and its nodules, as well as Thyroid Imaging Reporting and Data Systems (TIRADS) classification of all identified lesions. The results revealed very high concordance between conventional physician US and MTA US cine loop review for both size measurements and TIRADS classifications (r = 0.84-0.99, < 0.0001 each). Minor technical impairments were identified. The evaluated thyroid US cine loop SOP enables reliable second reading results and can be applied by non-physicians.
传统超声检查耗时，且结果在不同观察者之间差异较大。本研究旨在调查非医生（医学技术助理，MTA）应用的一种新型甲状腺超声动态环标准操作规程（SOP）的可靠性。连续纳入33例患者（22例女性，11例男性）。患者接受了由核医学医生进行的传统甲状腺超声检查，并根据当地的SOP由MTA进行额外的超声动态环检查，该SOP包括覆盖整个甲状腺的横向和纵向动态环。视频序列被传输到图像存档与通信系统（PACS）进行二次阅读。MTA的超声数据不用于医学报告，而是用于对PACS图像进行盲法二次阅读审查。比较了传统医生超声报告和审查后的MTA超声动态环在甲状腺及其结节大小测定以及所有已识别病变的甲状腺影像报告和数据系统（TIRADS）分类方面的结果。结果显示，在大小测量和TIRADS分类方面，传统医生超声和MTA超声动态环审查之间具有非常高的一致性（r = 0.84 - 0.99，P均< 0.0001）。发现了一些轻微的技术缺陷。所评估的甲状腺超声动态环SOP能够产生可靠的二次阅读结果，并且可以由非医生应用。
