Change: fracture of the sternum is, ipso facto, unimportant- the potential associated mediastinal trauma can be life-threatening. The radiographer proceeded to perform a lateral chest X-ray bearing in mind that a good visualisation of the sternum would be to great advantage. The radiographer has positioned the   View changes from previous version. (Word count: 711)

Change:  Compare the visualisation of the lateral sternum in this patient with the case above- it comes down to a question of how you are going to utilise the oblique rays- what's more important ... lateral posterior ribs or lateral sternum. In this case the decision is clear. The radiographer   View changes from previous version. (Word count: 719)

However, limitations of the technique should be appreciated.Case Study This patient presented to the Emergency   View changes from previous version. (Word count: 387)

Change: The possibility of extracting two images from a single exposure should always be considered. The limitations of the technique should be balanced against all of the relevant considerations at the time of the examination.

Whilst this image has some shortcomings, it does demonstrate that the lateral chest image above does not demonstrate the patient's sternum in the lateral position.   View changes from previous version.

Change:  With the introduction of digital radiography, radiographers are able to potentially create 2 images from a single exposure. One example of this digital double dipping is to create a lateral sternum image from a lateral chest image. Is this a legitimate approach and what are its limitations.Technique There   View changes from previous version. (Word count: 106)
