Last Updated:

Lunit INSIGHT CXR is an 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 connections, with proven versatility among different X-ray devices.

The AI solution generates (1) location information for detected lesions in color 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.

Certification

CE-marked

Development Stage

On the market

Deployment

Online & offline

Intended Age Group

14+ years (regulatory approval)

Target Setting

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

Current Market

Asia-Pacific, Europe, Middle East/North Africa, North America, South/Central America

Input

»» 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.

Output

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.
