RADS (Radiologists Score) for Smoke Inhalation Injury

Description

Calculates the RADS score to stratify the severity of smoke inhalation injury based on chest CT findings. The chest CT slice is divided into four quadrants, and each quadrant is scored based on the worst finding present. The total score for the slice ranges from 0 to 12. High scores (>8) are associated with a significantly increased risk of pneumonia, ARDS, and death.

Usage

rads_smoke_inhalation_score(quadrant1_finding, quadrant2_finding,
                            quadrant3_finding, quadrant4_finding)

Arguments

quadrant1_finding	String. Finding in the 1st quadrant. Options: "normal" (0 pts), "interstitial" (Increased interstitial markings, 1 pt), "ground_glass" (Ground glass opacification, 2 pts), "consolidation" (3 pts).
quadrant2_finding	String. Finding in the 2nd quadrant. Options: "normal", "interstitial", "ground_glass", "consolidation".
quadrant3_finding	String. Finding in the 3rd quadrant. Options: "normal", "interstitial", "ground_glass", "consolidation".
quadrant4_finding	String. Finding in the 4th quadrant. Options: "normal", "interstitial", "ground_glass", "consolidation".

Value

A list containing:

RADS_Score	The calculated total score (Range 0-12).
Risk_Category	Interpretation ("Lower Risk" <= 8, "High Risk" > 8).
