What imaging modality is best method for identifying rib fractures in a foal?

• A. Radiography
• B. Ultrasonography
• C. MRI
• D. CT

Answer: (B)

Ultrasonography is the most useful bedside imaging method for identifying rib fractures in foals because it lets you directly evaluate the rib cortex and surrounding soft tissues in real time, without moving the patient to a different room. The thin, sometimes cartilaginous ribs of foals and the proximity of soft tissues mean that subtle cortical disruptions or periosteal reactions are more readily visualized with ultrasound along the chest wall, and you can also assess for associated swelling or hematoma. This approach is fast, noninvasive, and can be performed at the stall side, which is especially important for fragile foals that can’t be easily transported. In contrast, plain radiography often misses fractures due to overlapping structures; CT provides superior bone detail but is less accessible, more costly, and usually requires anesthesia or sedation; MRI is impractical for acute rib injuries because of time, availability, and cost.
