M4CXR and DEEP:CHEST

DEEPNOID is a Seoul-based AI company listed on KOSDAQ since 2021 that develops generative AI for medical image reading and reporting, alongside industrial AI for security screening and factories. Its medical line targets radiologist shortages and reporting backlogs in hospitals.

M4CXR is a generative AI medical device that analyzes chest X-rays and automatically writes a preliminary report describing normal and abnormal findings across the lungs, heart, mediastinum, bones and abdomen, including pneumonia, tuberculosis, pneumothorax, nodules, cardiomegaly and fractures. Trained on 10 million chest X-rays, it generates a report in about 2.3 seconds. DEEP:CHEST supports multi-disease lung reading, and DEEP:NEURO detects cerebral aneurysms on MRA. Customers are Korean university and general hospitals and reading centers.

• Generative reporting: M4CXR writes preliminary reports with normal and abnormal chest X-ray findings.
• Whole-image coverage: lungs, heart, mediastinum, skeleton and abdominal cavity are described.
• Broad finding list: pneumonia, tuberculosis, pneumothorax, effusion, nodules, cardiomegaly, aortic changes and fractures.
• Speed: an average of 2.3 seconds per report, trained on 10 million chest X-rays.
• Lung reading aid: DEEP:CHEST supports detection of multiple lung diseases.
• Neuro modules: DEEP:NEURO for cerebral aneurysm reading and BrainSeg for quantitative brain MRI.

Teleradiology centers in Vietnam could use draft reports to speed up overnight chest X-ray reading for partner hospitals. Tuberculosis and lung screening campaigns could pre-screen large volumes of films and route abnormal ones to radiologists. Corporate health check-up providers could shorten turnaround time for chest X-ray results.

Produces a draft chest X-ray report in about 2.3 seconds, so radiologists edit rather than write from scratch. Covers findings across the whole radiograph, not just the lungs, reducing missed incidental abnormalities. Helps reading centers and hospitals handle large X-ray volumes with the same staff. Holds Korean MFDS approval with innovative medical device designation, supporting clinical adoption.

Generative AI is moving radiology tools from single-finding detection to full draft reports, which matters most where radiologists are scarce. Southeast Asian countries carry a high tuberculosis burden and growing chest X-ray volumes, and teleradiology hubs serving many hospitals are emerging in Vietnam and the region.

DEEPNOID Inc. is headquartered at Daeryung Post Tower 7 in Guro-gu, Seoul, and listed on KOSDAQ in August 2021. It opened a branch in Dubai in 2024. M4CXR holds MFDS approval with innovative medical device designation, and DEEP:NEURO and DEEP:CHEST have MFDS approval and temporary national health insurance listing. A core technology paper, RadZero, was accepted at NeurIPS 2025.
