Abstract


Objective: This pilot study reports inter-examiner agreement during analysis of the static alignment of the upper cervical spine seen on radiographic images.

 

Methods: Three interns with advanced radiographic training were asked to analyze the same digital images and the same conventional analog radiographs utilizing the HIO film marking process. Four categories were predetermined for analysis comparisons.

 

Results: Higher inter examiner agreements were observed in two of the four categories when the digital images were utilized.  Conventional analog films showed a higher inter examiner agreement in one category.

 

Conclusion: This feasibility study showed how these two radiographic technologies can be compared, how students can be involved in research as examiners, and that digital technology showed a slightly greater inter-examiner agreement.
