The Vetscan Imagyst system (Zoetis) is a novel, artificial intelligence-driven detection tool that can assist veterinarians in the identification of enteric parasites in dogs and cats. This system consists of a sample preparation device, an automated digital microscope scanner, and a deep-learning algorithm. The EasyScan One scanner (Motic) has had good diagnostic performance compared with manual examinations by experts; however, there are drawbacks when used in veterinary practices in which space for equipment is often limited. To improve the usability of this system, we evaluated an additional scanner, the Ocus 40 (Grundium). Our objectives were to 1) qualitatively evaluate the performance of the Vetscan Imagyst system with the Ocus 40 scanner for identifying Ancylostoma, Toxocara, and Trichuris eggs, Cystoisospora oocysts, and Giardia cysts in canine and feline fecal samples, and 2) expand the assessment of the performance of the Vetscan Imagyst system paired with either the Ocus 40 or EasyScan One scanner to include a larger dataset of 2,191 fecal samples obtained from 4 geographic regions of the United States. When tested with 852 canine and feline fecal samples collected from different geographic regions, the performance of the Vetscan Imagyst system combined with the Ocus 40 scanner was correlated closely with manual evaluations by experts. Sensitivities were 80.0‒97.0% and specificities were 93.7‒100.0% across the targeted parasites. When tested with 1,339 fecal samples, the Vetscan Imagyst system paired with the EasyScan One scanner successfully identified the targeted parasite stages; sensitivities were 73.6‒96.4% and specificities were 79.7‒100.0%.

使用 Ocus 40 和 EasyScan One 扫描仪对 Vetscan Imagyst 系统进行多中心评估，以检测狗和猫粪便中的胃肠道寄生虫。

Vetscan Imagyst系统（Zoetis）是一种新颖的人工智能驱动的检测工具，可以帮助兽医识别狗和猫的肠道寄生虫。该系统由样品制备装置、自动数字显微镜扫描仪和深度学习算法组成。EasyScan One扫描仪（Motic）与专家手动检查相比具有良好的诊断性能；然而，在兽医实践中使用时也存在一些缺点，因为设备的空间通常有限。为了提高该系统的可用性，我们评估了另一台扫描仪 Ocus 40 (Grundium)。我们的目标是 1) 定性评估 Vetscan Imagyst 系统与 Ocus 40 扫描仪在犬和猫粪便样本中识别钩口虫、弓蛔虫和鞭虫卵、等孢球虫卵囊和贾第鞭毛虫包囊的性能，以及 2) 扩大对Vetscan Imagyst 系统与 Ocus 40 或 EasyScan One 扫描仪配合使用，可包含从美国 4 个地理区域获得的 2,191 个粪便样本的更大数据集。当对从不同地理区域收集的 852 个犬科动物和猫科动物粪便样本进行测试时，Vetscan Imagyst 系统与 Ocus 40 扫描仪相结合的性能与专家的手动评估密切相关。目标寄生虫的敏感性为 80.0-97.0%，特异性为 93.7-100.0%。当使用 1,339 个粪便样本进行测试时，Vetscan Imagyst 系统与 EasyScan One 扫描仪配对成功识别出目标寄生虫阶段；敏感性为 73.6-96.4%，特异性为 79.7-100.0%。
