Positive area (intercostal spaces with ≥5B-line) and B-line score were correlated with total score on HRCT, FVC, DLCO, arterial blood gases, Borg Dyspneea Scale Score and 6MWT results. The mean value of HRCT score was 23 for IPF patients and 2.1 for control group. LUS score was 96.35 in IPF group, respectively 18.20 for control group. The number of chest positive areas was 8.57 for IPF and 0.80 in the control group. LUS score was correlated with HRCT score (r=0.88, p<0.001). Chest positive areas were also very good correlated with HRCT score (r=0.88, p<0.001). First textile for CT score was 3. Area under the ROC curve for LUS score using 9 as a HRCT score cut-off was 0.90, 95%CI (0.82-0.97), p<0.001, respectively for positive chest areas was 0.92, 95%CI (0.85-0.99), p<0.001. The sensitivity (Se) was 77.3% and the specificity (Sp) was 100.0% for the cut-off 52.5 thoracic ultrasound score, obtained with ROC curve procedure; as for positive chest areas with intercostal space with ≥5 B-line the Se=81.8% and Sp=100.0% for the cut-off 5.5 positive intercostal spaces. LUS is a noninvasive, radiation-free imagining technique that can become an important tool to screen IPF patients but further studies are warranted on this topicFootnotesCite this article as: European Respiratory Journal 2019; 54: Suppl. 63, PA4696.This is an ERS International Congress abstract.
