Researchers Develop Artificial Intelligence Tool in Chest X-Rays to Predict Long Term Mortality

Each image was paired with a key piece of data: Did the person die over a 12-year period?

Researchers have developed an Artificial Intelligence (AI)-powered tool that can harvest information in chest X-rays to predict long-term mortality.

The findings of this study, published in the journal JAMA Network Open, could help to identify patients most likely to benefit from screening and preventive medicine for heart disease, lung cancer and other conditions.

“This is a new way to extract prognostic information from everyday diagnostic tests,” said one of the researchers, Michael Lu, from Massachusetts General Hospital (MGH) of Harvard Medical School. “It’s information that’s already there that we’re not using, that could improve people’s health,” Lu said. Lu and his colleagues developed a convolutional neural network – an AI tool for analysing visual information – called CXR-risk.

It was trained by having the network analyse more than 85,000 chest X-rays from 42,000 participants who took part in an earlier clinical trial. Each image was paired with a key piece of data: Did the person die over a 12-year period? The goal was for CXR-risk to learn the features or combinations of features on a chest X-ray image that best predict health and mortality.

Next, Lu and colleagues tested CXR-risk using chest X-rays for 16,000 patients from two earlier clinical trials. They found that 53 per cent of people the neural network identified as “very high risk” died over 12 years, compared to fewer than four per cent of those that CXR-risk labeled as “very low risk.”

The study found that CXR-risk provided information that predicts long-term mortality, independent of radiologists’ readings of the x-rays and other factors, such as age and smoking status. Lu believes this new tool will be even more accurate when combined with other risk factors, such as genetics and smoking status.

Samsung Electronics created an in-house technology platform unit and named a new chief for its home appliance business in the company’s latest reshuffle, corporate sources said here on Thursday.

Samsung combined its in-house tech units related with Artificial Intelligence (AI), Internet of Things (IoT) and big data solutions to set up a new tech group, tentatively named “next-generation platform centre,” Yonhap news agency reported, citing company officials.

The centre will be headed by Chung Eui-suk, an executive vice president who is best known for leading the development of Samsung’s AI-based digital assistant, Bixby. The South Korean tech giant also appointed Lee Jae-seung, former Consumer Electronics (CE) business division development team leader, to head its home appliance business.

Previously, Kim Hyun-suk, President and CEO of Samsung’s CE business division, co-held the title as home appliance business chief. It was revealed in Samsung’s senior executive reshuffle on Monday that Kim no longer heads the company’s home appliances business, although he retains his CEO position for Samsung’s CE business division.

Lee Won-jin, an executive vice president who leads the service business team at Samsung’s visual display unit, will serve the same job for the company’s mobile business unit. The move will allow Lee, former managing director at Google Korea, to focus on developing contents services for both mobile phones and TVs.

The latest reshuffle follows changes to leadership at Samsung on Monday. Earlier the company named a new mobile business chief, and promoted 162 executives.
