AiAi.care code-charity is working to reduce Tuberculosis πŸ‘Ύ and Lung Cancer screening time by 90%, reduce screening cost by 90%, and supercharge survival probability by 5XπŸš€ through early detection.

We are using Machine Learning + 250,000 Chest X-Rays to build an FDA πŸ’Š approved, open-source screening CAD (Computer Aided Detection) tool. After an MRMC clinical trial, AiAi CAD will be distributed for free to developing 🌏 countries (Vietnam, India, Belarus), charitable hospitals, and organizations like WHO. ETA Q2 2018

Why Lung Cancer Algorithm

When it comes to cancer, early detection delivers a huge delta in survival rates compared to late detection. Unfortunately, Lung Cancer is mostly asymptomatic in earlier stages so detections in developing countries happen around Stage (III A). This late detection causes more people to die of lung cancer than of colon, breast, and prostate cancers combined.

Cancer Stage:


5-Yr Survival:


71% of lung cancers detected in chest X-Rays were visible in retrospect on previous imaging studies. Furthermore, a 1999 NIH long-term study of American Radiologists found that 19% missed lung cancers present in current chest X-Rays. These numbers may be more stark for developing nations where X-Rays are read by Primary Care Physians (PCP) instead of Radiologists.

Herein lies a 5X life-saving opportunity for early detection: We propose that a Machine-Learning screening tool with class leading sensitivity and specificity can help reduce missed-diagnose opportunities, and as a result improve survival rates 5X through early detection.

Baseline Sensitivity and Specificity Targets

According to a JDI paper, commercial CAD algorithm OnGuard v5.2 for lung cancer detection in CXR images provided 77.78% sensitivity with 32% false-positives and 55.7% test efficiency (Ref: Journal of Digital Imaging (2013) 26:651–656 DOI 10.1007/s10278-012-9565-4). I am aiming to beat all three numbers with our project by applying latest breakthroughs in Artificial Intelligence and Deep Learning.

For reference, experienced Radiologist’s Lung Cancer sensitivity is 67.5% and specificity is 91% according to (Ref: PLOS ONE | DOI:10.1371/journal.pone.0136624)

Price of Commercial πŸ’Έ CADs

An FDA-approved commercial CADe / CADx package costs $50,000 per year for low volume radiology facilities that consult <20 patients per day. A typical large hospital license with hundreds of studies per day costs $500,000🧐 per year or more.

These costs are entirely out of reach for developing countries and charitable hospitals. This is why we are building AiAi to provide a free πŸ—½ FDA-approved, open-source alternative to the world.

CAD algorithms from GE, Philips, Siemens are too expensive for charitable hospitals in developing countries.
