Systematic radiographic technical evaluation (mnemonic)

Dr Daniel J Bell and Andrew Murphy et al.

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:

  • PACEMAN
  • IMAACREAP

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

Mnemonics

PACEMAN
  • 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 
IMAACREAP
  • 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?
