To report on the feasibility, indications, and diagnostic yield of cone beam computed tomography (CBCT) of horses' extremities performed under standing sedation.
Retrospective clinical case series.
Fifty-nine CBCT examinations in 58 horses.
Examinations were categorized for indications for CBCT dependent on a suspicion, presence, or absence of a diagnosis prior to CBCT. The number of acquisitions per examination, total time for the examination, diagnostic score of each acquisition (diagnostic, diagnostic-compromised, nondiagnostic), and additional diagnostic information regarding preexisting diagnostic information were recorded.
Three (median) acquisitions were performed per examination in a median study time of 14 minutes. In 24 of 33 cases with a suspected diagnosis, this diagnosis was confirmed or definitively refuted; in seven of 33 cases, the suspected diagnosis was refuted without a new diagnosis; and, in two of 33 cases, the suspected diagnosis could not be confirmed nor could a new diagnosis be made. In five of nine cases without a preexisting diagnosis, a diagnosis was established. In 16 cases with a diagnosis prior to CBCT, additional information was recorded, or a surgical plan was prepared. In 14 of 18 cases in which additional contrast techniques were used, additional information was gained.
Standing CBCT of the horses' extremities is feasible and can produce diagnostic information in a timely fashion.
The results provide evidence of the practicality and diagnostic potential of standing CBCT of horses' extremities.
报告在站立镇静下进行马四肢锥形束计算机断层扫描（CBCT）的可行性、适应证和诊断率。
回顾性临床病例系列。
58 匹马的 59 次 CBCT 检查。
根据 CBCT 前的怀疑、存在或不存在诊断，将检查分为 CBCT 的适应证类别。记录每次检查的采集次数、检查总时间、每次采集的诊断评分（诊断、诊断受限、无诊断），以及关于先前存在的诊断信息的其他诊断信息。
每次检查平均进行 3 次（中位数）采集，平均检查时间为 14 分钟。在 33 例有可疑诊断的病例中，24 例证实或明确排除了该诊断；在 33 例中，7 例排除了可疑诊断而没有新的诊断；在 33 例中，2 例可疑诊断既不能确认也不能做出新的诊断。在 9 例无先前诊断的病例中，建立了诊断。在 16 例 CBCT 前有诊断的病例中，记录了额外的信息，或制定了手术计划。在 18 例使用了额外对比技术的病例中，有 14 例获得了额外的信息。
马四肢站立 CBCT 是可行的，可以及时提供诊断信息。
结果为马四肢站立 CBCT 的实用性和诊断潜力提供了证据。
