The purpose of this study was to produce an anatomic reference for computed tomography (CT) of the head of the foal for use by radiologists, clinicians, and veterinary students. The head from each of 2 foals, euthanized for reasons unrelated to head pathology, was removed and prepared for CT scanning. Using a third-generation CT scanner, 5-mm contiguous transverse images were acquired. The heads were then frozen and sectioned using a band saw, with the cuts matched as closely as possible to the CT slices. The anatomic sections were photographed and radiographed. The radiographs and anatomic photographs were digitized and matched with the corresponding CT image. Each CT image was compared with its corresponding radiographic and anatomic section to assist in the accurate identification of specific structures. Clinically relevant structures were identified and labeled in corresponding images (CT, anatomic slice, and radiograph of slice). Only structures identified in the CT image were labeled in 1 of the other 2 images. Sagittal (reference) images of the horse's head were reconstructed from the transverse CT scans, and were used to indicate the level from which each of the transverse images was obtained. Corresponding labeled images were then formatted together with a legend for identification of specific anatomic structures.
本研究的目的是为放射科医生、临床医生和兽医专业学生提供一份用于马驹头部计算机断层扫描（CT）的解剖学参考资料。选取2匹因与头部病变无关的原因实施安乐死的马驹，取下其头部并准备进行CT扫描。使用第三代CT扫描仪获取5毫米连续的横向图像。然后将头部冷冻，用带锯切片，切片尽可能与CT切片匹配。对解剖切片进行拍照和放射摄影。将放射照片和解剖照片数字化，并与相应的CT图像匹配。将每张CT图像与其相应的放射照片和解剖切片进行比较，以帮助准确识别特定结构。在相应图像（CT、解剖切片和切片放射照片）中识别并标记临床相关结构。仅在CT图像中识别出的结构会在其他两张图像中的一张上进行标记。从横向CT扫描重建马头部的矢状（参考）图像，用于指示获取每张横向图像的层面。然后将相应的标记图像与图例一起格式化，以识别特定的解剖结构。
