Key Points

The study aims to assess the effectiveness of scatter correction in emergency lateral cervical spine radiography.
Used water-equivalent phantoms with lead disks or aluminum plates to test exposures.
Varying air gap distances were implemented during imaging.
Measured scatter rates and post-processing metrics like SDNR and contrast for different image types.
Conducted visual evaluations comparing scatter correction images with grid and non-grid images.
Scatter correction images showed lower scatter rates as air gaps increased, especially at 20 cm.
SDNR and contrast in scatter correction images were significantly higher than grid images at air gaps of 15 cm and 20 cm.
Visual evaluations rated scatter correction images significantly higher for quality, except for granularity.

Answers are grounded in this paper and cite their sources.

Examination reveals enhanced image quality in emergency cervical spine radiography, suggesting scatter correction is beneficial.
