Computed Tomography (CT)

C.

X-ray (Radiography)

D.

Ultrasound

Answer and Explanation

The Correct Answer is C

X-ray (radiography) is the most common imaging modality used to diagnose fractures in the emergency department. X-rays can visualize the bone's structure and detect fractures, bone displacement, or other abnormalities.

  
a. Magnetic Resonance Imaging (MRI): MRI is useful for soft tissue evaluation but is not routinely used for initial fracture diagnosis in the emergency department.
b. Computed Tomography (CT): CT scans provide detailed cross-sectional images of bones and soft tissues, but they are not typically the first-line imaging for initial fracture assessment in the emergency department.
d. Ultrasound: Ultrasound is useful for certain soft tissue evaluations but is not commonly used for diagnosing fractures.
