Change: The radiographer has used lead rubber shielding to minimise the scatter radiation fog. This approach is effective, but is untidy and can produce some undesirable confusing artifacts (arrowed). You could argue that the scatter radiation fog is preferable to the confusing artifacts!This approach can cause

Change: Beware the radiographer who insists on a particular technique but can't explain their viewpoint based on an objective and a balanced appraisal of the advantages and disadvantages of their technique (with supporting evidence). Many techniques are simply historically based (not that there is anything wrong with that per se).

Change: The scaphoid view demonstrates a radial metaphysis fracture (arrowed). This case supports the arguement for not coning teh X-ray beam too tightly when performing the scaphoid view. Interstingly, the fracture of the distal radius was demonstrated most convincingly on this view.MRI Imaging of Wrist TraumaMRI imaging

Change: Yet another consideration is whether you perform a series of tube angles in patients who have convincing clinical evidence of a scpahoid fracture but no radiographic evidence on routine views. This is arguably reasonable if there is good diagnostic yield in patients who would otherwise be referred for MRI imaging.
