The application of anatomical side markers during abdominal and IVU examinations: An investigation of practice prior to and post-installation of computed radiography (CR)

Abstract 

Professionally, radiographers are accountable for their practice. Available literature highlights the ramifications of not using anatomical side markers within the primary beam. It was thought by the authors that the installation of a computed radiography (CR) system could potentially cause a change in practice due to the ease of adding anatomical side markers manually/electronically during post-processing. This study assessed anatomical marker use within the primary beam at a district general hospital in East Anglia, one-year pre-CR installation and one-year post-CR installation. 100 abdominal images were evaluated from each time period and the presence of anatomical side markers was recorded and compared to establish any significant change. The study showed that although there was a decline in use of anatomical side markers used within the primary beam post-CR installation (from 32% to 25%), the changes were not statistically significant (p>0.05). However, the agreed standard of 100% images having the primary beam side marker present was not met. There is a conflict of opinion about the necessity for anatomical side markers to be used within the primary beam. However, the researchers believe there is a case for recommending alterations and improvements to practice to comply with ‘best practice’ requirements.
