The purpose of this study was to evaluate the diagnostic equivalence, radiation dose, clinical usefulness and radiographic aspects of a low-dose, full-body digital X-ray machine in a busy trauma unit. A digital trauma X-ray machine known as "LODOX" was compared with conventional radiography between June 1999 and November 2001 in the Groote Schuur Hospital Trauma Unit, Cape Town. Digital images of a variety of body regions commonly imaged in trauma were compared for diagnostic image quality in a number of categories with equivalent conventional radiographs. ⋯ FDA approval is awaited. Projected cost is similar to that of flat-panel digital units. This digital unit was felt to be diagnostically substantially equivalent to conventional radiographs, with low-dose full-body imaging, improved workflow, digital technology and long-term cost benefits as potentially favourable contributions to trauma imaging.
