FIGURE 2

The Radiographic Assessment of Lung Edema (RALE) Scores by Chest-X-Ray confirmed the improvement of the lung involvement after Low Level Leaser Therapy for the patient. A score of 0-4 was assigned to each ling, depending on the extent of lung involvement by consolidation or ground glass opacities. 0 = no lung involvement; 1 = <25%; 2 = 25 - 50%; 3 = 50% - 75%; 4 = >75% involvement. The scores for each lung were summed up to calculate the final severity score. The RALE Scores for the patient were 8, before laser therapy, and 3, after laser therapy (6 days later).
