We read with interest the paper by Nguyen et al. reporting a series from 2001 to 2003 on CT-imaging clinically suspected scaphoid fractures. We have two concerns regarding the conclusions of this study. First, we suggest that the findings of this historic study may have been superseded in the era of multi-detector computerised tomography. Second, we would be interested to know what the false negative rate was for CT in this study and how this might have been established. We suggest that limited sequence acquisition with magnetic resonance (Coronal T1 and STIR) would have had a lower false negative rate and greater positive and negative predictive power, without exposure to ionising radiation - particularly important in dealing with a potentially disabling pathology in young people.1 This has been shown to be a cost-effective strategy.2-3
