These systems can prioritize scans with critical findings, reducing the radiologist's workload and speeding up turnaround times.
The goal is not to replace human experts but to augment their capabilities, making them more efficient and precise. Startups are developing sophisticated AI platforms that can analyze a chest X-ray in a matter of seconds, providing a critical "second opinion" to radiologists.
AI systems are being trained to analyze digital pathology slides and blood samples to automate the detection of abnormalities. In cancer diagnosis, for example, AI algorithms can identify and quantify cancer cells in biopsy images with high accuracy. This not only makes the process faster and more scalable but also reduces the risk of human error. India's Neuberg Diagnostics has already embraced this technology, integrating AI and digital pathology into its operations.
AI's predictive capabilities are a game-changer for managing chronic diseases. By analyzing historical patient data, including genetic information, lifestyle, and lab results, AI models can predict the progression of diseases and identify individuals at high risk.
This enables doctors to intervene earlier and create personalized treatment plans that are more effective and have fewer side effects. This approach is particularly valuable for conditions like diabetes and cardiovascular ailments, which are prevalent in India.
AI is making healthcare more mobile and accessible. AI-powered mobile apps and portable diagnostic devices allow healthcare workers to perform basic screenings in remote and rural areas. For instance, AI-driven retinal imaging devices can screen for diabetic retinopathy, a leading cause of blindness, without the need for a specialist. These tools enable remote specialists to interpret results and provide diagnoses, significantly reducing wait times and travel burdens for patients.
