Finger (PA view)

Dr Aditya Shetty et al.

Finger PA view is a standard projection for radiographic assessment of the fingers; it is one of three views of the finger series

  • patient is seated alongside the table (similar to the projection of hand)
  • palmar aspect of pronated hand is placed over detector and extended fingers are kept in its contact with little separation, allowing interphalangeal joint spaces to appear open.
  • posteroanterior projection
  • centring point
    • approximately over the proximal interphalangeal joint
  • collimation
    • laterally to the adjacent fingers 
    • proximal to include the carpometacarpal joint
    • distal to the tips of the distal phalanges 
  • orientation  
    • portrait
  • detector size
    • 18 cm x 24 cm
  • exposure
    • 50-60 kVp
    • 1-5 mAs
  • SID
    • 100 cm
  • grid
    • no

Digit is visualised to include the carpometacarpal joint. Alongside finger is included to ensure the correct finger identified. The concavity of the metacarpal shafts is equal.

The PA finger is not a technically challenging radiograph, always ensure the fingers are equal distance apart and either label or include adjacent fingers to prevent any diagnostic errors 2
