Figure 3. Radiographic Assessment of Lung Edema (RALE) by CXR showed reduced ground-glass opacities and consolidation following PBMT. Lung radiographic score is dependent on extent of involvement based on consolidation or ground-glass opacities for each lung. Total score is the sum of both lungs. Scores classification: 0 – no involvement; 1 – <25% of lung involved; 2 – 25–50% of lung involved; 3 – 50–75% of lung involved; 4 – >75% of lung involved. RALE score before laser therapy (04-27-2020)=8. Laser therapy started on (04-29-2020). RALE score after laser therapy (05-03-2020)=5.
