AI solution for radiology that detects 10 radiologic findings with high accuracy on chest x-rays

Developed using Lunit’s cutting-edge deep learning technology, Lunit INSIGHT CXR accurately detects 10 of the most common findings in a chest x-ray, which includes atelectasis, calcification, cardiomegaly, consolidation, fibrosis, mediastinal widening, nodule, pleural effusion, pneumoperitoneum, and pneumothorax. The AI (Artificial Intelligence) solution generates (1) location information of detected lesions in the form of heatmaps, (2) abnormality scores reflecting the probability that the detected lesion is abnormal, and (3) an AI “case report” that summarizes the analysis result by each finding. The solution is indicated to be directly involved in the primary interpretation process of radiologists or clinicians.
