Summary
# Editorial Summary Understanding the normal thoracic anatomy of neonatal foals is essential for interpreting diagnostic imaging in sick or compromised newborns, yet detailed reference material has been limited. Researchers obtained contrast-enhanced CT angiography scans of three neonatal foals using a helical scanner with bone, mediastinal, and lung window settings, then directly correlated these images with gross dissections and anatomical sections from the same individuals to establish a precise anatomical reference standard. The multi-modal approach revealed distinct CT density patterns for different thoracic tissues and provided clear visualisation of intrathoracic cardiovascular structures, creating a validated anatomical template against which future neonatal thoracic pathology can be interpreted. For practitioners involved in managing foal health—particularly vets performing diagnostic imaging—this work offers crucial baseline data for recognising normal anatomical variants and detecting abnormalities in the mediastinal and cardiac structures during the critical neonatal period. The combination of CTA imaging with direct anatomical correlation establishes a reliable framework that should improve diagnostic accuracy in young foals presenting with thoracic or cardiovascular concerns.

Practical Takeaways
- •CTA provides a reliable imaging method for detailed assessment of thoracic and cardiovascular anatomy in neonatal foals with normal reference anatomy now established
- •Understanding CT density patterns in bone, mediastinal, and lung windows is essential for accurate interpretation of foal thoracic imaging
- •This anatomic reference can guide clinical diagnosis and assessment of thoracic abnormalities in neonatal foals presenting with cardiopulmonary concerns
Key Findings
- •CTA imaging successfully correlated with anatomical sections and gross dissections in three neonatal foals, establishing a valid anatomic pattern for thoracic structures
- •CT density characteristics of different organic tissues (bone, mediastinal, and lung windows) provided reliable identification of intrathoracic cardiovascular structures in neonatal foals
- •Volume-rendered cardiac reconstructions from CTA provided detailed visualization of cardiac anatomy in neonates
- •CTA technique and anatomic reference data established utility for clinical interpretation of thoracic imaging in neonatal foals
