Lunit INSIGHT CXR is an artificial intelligence (AI) solution that detects 10 different radiologic findings on chest X-rays including tuberculosis (TB). It is designed to provide a quick analysis in hard-to-reach areas regardless of internet connection, with proven versatility among different X-ray devices.

The AI solution generates (1) location information for detected lesions in colour or outline, (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.


CE-marked Class I, Korea MFDS

Development Stage

On the market


Online & offline

Intended Age Group

6+ years

Target Setting

Primary health centres, general hospital (above primary level), teleradiology companies, government/public sector, e.g. national TB programme, private sector

Current Market

Currently being used in over 80 countries


»» Can be used to read images from any kind of chest X-ray machine (vendor neutral)

»» Chest X-ray image format: DICOM

»» Chest X-ray type: posterior-anterior chest X-ray, anterior-posterior chest X-ray, portable

»» Other requirements: product requires upload of an original image in the standard DICOM-format which contains appropriate DICOM metadata information in specific DICOM tags


Structured report including: 

» Heat map 

» Probability score as well as dichotomous output indicating whether each abnormality is present or absent 

» Probability score as well as dichotomous output indicating whether TB is likely present or likely absent 

» Specification of the location of each abnormality 

Default threshold probability score is set at 15% for all abnormalities including TB. 

Chest abnormalities detected by the product for which a separate abnormality score is given include: atelectasis, calcification, cardiomegaly, consolidation, fibrosis, mediastinal widening, nodule, pleural effusion, pneumoperitoneum, pneumothorax, and TB.
