During the workup for hypothermia, which imaging is used to assess for infection or aspiration?

• A. Chest X-ray
• B. Abdominal CT
• C. Head MRI
• D. Doppler ultrasound

Answer: (A)

When evaluating hypothermia, it’s important to look for sources like infection or aspiration that could have precipitated it. A chest radiograph is the best initial imaging because it quickly screens the lungs for signs of pneumonia or aspiration pneumonitis, which are common contributors in hypothermic patients. It’s fast, widely available, and can guide management decisions such as antibiotic therapy or airway concerns. If suspicion remains high despite a normal chest X-ray, more advanced imaging (like CT) can be considered, but the chest X-ray is the most appropriate first step. Abdominal CT, head MRI, and Doppler ultrasound serve other purposes—abdominal pathology, CNS issues, and vascular problems, respectively—and aren’t as directly useful for assessing infection or aspiration in this context.
