摘要
【ABSTRACT】Knowledge of the radiographic anatomy of rodent skulls is essential for accurately interpreting extra‐oral radiographs, a non‐invasive diagnostic tool commonly used in veterinary practice. Due to the complexity of the skull and the potential for distortion in two‐dimensional views, a systematic evaluation of anatomical structures is necessary. This study identifies the most clinically relevant anatomical landmarks on standard extra‐oral radiographic views of the skull and mandible in various rodent species, including a cane rat, two woodchucks, and seven common mole rats. Specimens were evaluated with bone and soft tissue intact, as well as dried skulls, to identify key anatomical features. The findings highlight distinct species‐specific variations despite general similarities in skull structure. These landmarks were catalogued to aid veterinary professionals in interpreting rodent radiographs. Improved recognition of these structures enhances diagnostic accuracy, enabling better assessment of normal anatomy and potential pathological conditions in rodent patients.

【摘要】了解啮齿动物头骨的放射学解剖学对于准确解释射线照相仪是必不可少的，这是一种非侵入性诊断工具，通常用于兽医实践。由于头骨的复杂性和在二维视图中的变形潜力，需要对解剖结构进行系统评估。这项研究确定了各种啮齿动物物种中标准的颅骨和下颌骨视角上临床上最相关的解剖标志物，包括甘蔗大鼠，两只木木和七个常见的摩尔大鼠。用骨骼和软组织完整以及干燥的头骨评估样品，以识别关键的解剖特征。尽管头骨结构一般相似，但这些发现突出了不同的物种特异性变化。这些地标被分类以帮助兽医专业人员解释啮齿动物X光片。对这些结构的改善识别提高了诊断准确性，从而可以更好地评估啮齿动物患者正常解剖结构和潜在病理状况。
