The detection of wooden foreign bodies: An experimental study comparing direct digital radiography (DDR) and ultrasonography

Poor sensitivities and specificities were identified in this study. However, this study shows that ultrasound remains superior to DDR at identifying small foreign body objects. This study demonstrates that ultrasound can be a clinically effective tool for detecting suspected wooden FBs >5 mm in the foot and thus should be considered as the primary imaging modality of choice for referring clinicians.
