Systematic radiographic technical evaluation (mnemonic)

Last revised by Andrew Murphy on 23 Mar 2023

Systematic radiographic technical evaluation is an important aspect to evaluative, effective radiography. It is the process of assessing a radiographic image to ensure it meets a high level of diagnostic standard. Two mnemonics are commonly used when assessing a radiographic image:


Although the use of plain radiographic technical evaluation seems overtly academic, radiographers will subconsciously go over a checklist like this after every examination.


  • P: positioning
  • A: is the anatomical area covered adequately
  • C: collimation present
  • E: exposure is within range
  • M: marker present and correct
  • A: aesthetics
  • N: name is correct 
  • I: identification, ensuring correct patient was imaged
  • M: markers are present and correct
  • A: anatomy of interest is assessed and adequately covered  
  • A: artifacts are noted/assessed for  
  • C: collimation present
  • R: relative position to the central beam (centering)
  • E: exposure is within range
  • A: any additional imaging required? (repeat, supplementary views)
  • P: pathology present that requires specialized projections i.e. horizontal beam hip?
