Oh et al evaluated the importance of the admission chest CT scan for a patient with a thermal burn. The radiologist can score each slice of the CT for the changes seen. The authors are from Fort Sam Houston in Texas.
Patient selection: thermal burn
Analysis: chest CT scan
Each slice is scored separately.
For each slice the left lung is divided into 4 quadrants and the right lung is divided into 4 quadrants.
Each quadrant is scored based on the most severe finding.

score for the slice =
= SUM(points for all 8 quadrants)
final score =
= SUM(RADS for all slices)
average RADS per slice =
= (final score) / (number of slices)
