Abstract
Aim To compare image quality of lateral skull radiographs using computerised radiography (CR) with or without the use of secondary radiation grids. Methods and materials 100 adult patients referred for lateral skull radiography from the accident and emergency department were randomised so 50 were examined using a secondary radiation grid and 50 without. Three consultant radiologists blinded to the randomisation then individually reviewed the image quality depending on a set of pre-determined criteria. Results There is no statistical difference in image quality between lateral skulls exposed with or without the use of a secondary radiation grid when applied to computerised radiography. Conclusion Secondary radiation grids can be removed for lateral skull radiography, using CR with no deterioration in image quality.
