Fluoroscopy vs fluorography

Last revised by Andrew Murphy on 01 Feb 2021

Fluoroscopy and fluorography are very similar imaging techniques and, in many instances, can be performed on the same equipment.

Fluoroscopy vs fluorography

  • low current (0.5-5 mA), continuous or near-continuous x-ray exposures
  • relatively low signal to noise ratio (SNR)
  • prioritises temporal resolution for procedures
  • 512 x 512 pixel matrix with 8-bit greyscale
  • real-time imaging viewed on a display monitor in the clinical room
  • relatively intense (50-1000 mA), pulsed x-ray exposure (pulses are of short duration and applied at 1-12 pulses/second)
  • relatively high SNR
  • prioritises spatial resolution for diagnostic purposes
  • 1024 x 1024 pixel matrix with 10-bit greyscale
  • images usually viewed after acquisition
