CT imaging is indicated to evaluate which structures, especially with a history of trauma?

• A. Lungs and Airways
• B. Sinuses and Ethmoids
• C. Gastrointestinal Tract
• D. Hoof Capsule

Answer: (B)

CT imaging is especially useful for assessing the facial bone region after trauma because it provides detailed, cross-sectional, high-resolution views of the complex sinus and ethmoid anatomy. The paranasal sinuses and ethmoid area are a maze of thin bones and air-filled spaces, and plain X-rays can miss subtle or displaced fractures. CT clearly shows fracture lines, bone fragments, and whether surrounding structures like the nasal passages or orbital walls are involved, which is crucial for accurate diagnosis and planning treatment. While CT can image other areas such as the chest or abdomen in trauma, the greatest diagnostic yield in this context is for the sinuses and ethmoids.
