The most appropriate imaging modalities for evaluating a suspected pneumothorax are a chest X-ray or CT scan. A chest X-ray is often the first-line imaging technique used in emergency settings because it is quick, readily available, and effective for visualizing the presence of air in the pleural space. It can also help in assessing the size of the pneumothorax and any potential mediastinal shift or associated injuries.

A CT scan provides a more detailed view and may be utilized in cases where the diagnosis is uncertain or when evaluating more complex thoracic injuries. It can also detect smaller pneumothoraces that may not be visible on a standard chest X-ray and is useful for assessing additional thoracic abnormalities.

While other imaging options and methods exist, such as ultrasound for certain scenarios or advanced imaging like PET scans, they are not standard practice for pneumothorax evaluation. MRI is not typically used due to its limitations in assessing air and the time required for scanning, making it impractical in acute settings for this specific condition.
