Through a recent blog, Facebook has revealed its decision to partner with New York University’s School of Medicine’s radiology department to transform the traditional MRI process.

Harnessing digital tools such as AI, MRI’s have the potential to be undertaken up to 10 times faster, reducing scans to just five minutes. This would be highly advantageous for those who are uncomfortable lying down for long periods of time, those who have a fear of enclosed spaces, as well as young children who can be frightened by such an experience.

Additionally, with rural areas and a global ageing population, wait times, particularly in rural areas, continue to grow as a result of such a time-consuming process.

With increased demands for MRI scans, medical professionals are provided with detailed information of soft tissues through the creation of cross-sectional images. However, the larger the area, the longer the process will take. Amplifying the speed will therefore deliver increased accessibility and reduce the risk of ionizing radiation for patients, delivering a more positive patient experience with enhanced results.

By effectively training artificial neural networks to recognise all structures within the body, high quality images will be produced with less data used.

“It is similar to how humans process sensory information. When we experience the world, our brains often receive an incomplete picture — as in the case of obscured or dimly lit objects — that we need to turn into actionable information. 

Early work performed at NYU School of Medicine shows that artificial neural networks can accomplish a similar task, generating high-quality images from far less data than was previously thought to be necessary,” explained Larry Zitnick, Facebook Artificial Intelligence Research (FAIR), Dr Daniel Sodickson and Michael Recht, MDs, NYU School of Medicine.

"We have some great physicists here and even some hot-stuff mathematicians, but Facebook and FAIR have some of the leading AI scientists in the world," added Dr Sodickson.

Utilising three million, anonymised magnetic resonance images in up 10,000 clinical cases, in adherence with HIPAA, the partners will implement machine learning technology and data mining to overhaul the entire process, which will be fully supported through the use of AI.

With the aim to provide breakthroughs and advance medical imaging as quickly as possible, the duo has also embraced open-source to enable the wider research community to support its development further.

Such advances will not only seek to transform the MRI process, but also other medical imaging tools, such as X-rays and computed tomography (CT).

NHS opens 8 clinical trial sites to assess cancer treatment

NHS and OncoHost to launch clinical trials analysing cancer patients response to immunotherapy

The UK's National Health Service (NHS) is opening eight clinical trial sites to assess patients' responses to personalised cancer therapy. 

The trials will analyse how patients diagnosed with advanced melanoma or non-small cell lung cancer respond to immunotherapy, to help predict their response to treatment.  They will be hosted at Gloucestershire Hospitals NHS Foundation Trust facilities. 

Immunotherapy helps the body's own immune system fight cancer, but while it has achieved good results for some cancer patients, it is not successful for everyone. Finding ways to predict which people will respond to the treatment is a major area of research.

OncoHost, an oncology startup,  will provide advanced machine learning technology to develop personalised strategies aiming to improve the success rate of the cancer therapy. The trials will contribute to OncoHost’s ongoing PROPHETIC study, which uses the company’s host response profiling platform, PROphet®

“Immunotherapy has achieved excellent results in certain situations for several cancers, allowing patients to achieve longer control of their cancer with maintained quality of life and longer survival,” said Dr David Farrugia, Consultant Medical Oncologist at NHS, and chief investigator of all eight NHS clinical trial sites.

“However, success with immunotherapy is not guaranteed in every patient, so this PROPHETIC study is seeking to identify changes in proteins circulating in the blood which may help doctors to choose the best treatment for each patient." 

"I am excited that Gloucestershire Oncology Centre and its research department have this opportunity to contribute to this growing field of research and I am determined that our centre will make a leading national contribution in patient recruitment.”

Previous studies in the US and Israel have shown that PROphet® has high accuracy in predicting how patients with cancer will respond to various therapies.
