What is the initial imaging modality for suspected cervical infection?

• A. X-ray
• B. Ultrasound
• C. MRI of the cervical spine with contrast
• D. CT with contrast

Answer: (D)

When a cervical infection is suspected, the goal is to quickly determine if deep neck spaces are involved, whether an abscess is present, and how far the infection has spread to guide urgent management. CT with contrast provides fast, widely available imaging that vividly shows soft tissue detail, fluid collections, gas in tissues, and the boundaries between neck fascial planes. This lets you identify an abscess versus cellulitis, map the extent of infection toward the airway or mediastinum, and plan drainage or surgical intervention if needed. X-ray has limited sensitivity for soft tissue infection; ultrasound is useful mainly for superficial lesions and is highly operator-dependent; MRI offers excellent soft-tissue detail but takes longer, is less accessible in urgent settings, and may be impractical for unstable patients. Thus, CT with contrast is the best initial imaging modality to promptly evaluate suspected cervical infection.
