Lyonnais Imadis is betting on AI to improve the efficiency of care offers

“We’ve quickly realized the interest in artificial intelligence to improve our services. We’ve started experimenting with technologically mature solutions as proposed. Results? Today, AI has become one of our strengths of difference.”Alexander Benn, co-founder of the Leon-based Medtech company Imadis, exhibits checks.

Created in 2008 by five young radiologists graduating from Hospices Civils de Lyon (HCL), Imadis has created an innovative remote emergency radiology offer. Its model is based on an organization inspired by SAMU, which covers the French territory and where the team comes to work, is a medical radiologist (also a generous or hospital doctor).

With an observation:

“Partner organizations, hospital emergency services do not always have the resources, especially at night, for patients to have their radio interpreted by a radiologist. They can then call tele-radiology. , So that the patient can be treated as soon as possible. “Alexander Ben Czech explains.

An offer consistent with the strong trend of establishing telemedicine in France, ensuring that all patients receive permanent care regardless of their place of residence.

One significant difference, however, is that compared to many players in the sector: on-call radiologists from Imadis do not conduct their missions from their home, as is usually the practice, but in several centers specially equipped for this activity and where they work as a team. (Lyon, Bordeaux, Marseille and, for a few months, Renaissance and Saint-Etienne).

Five AI algorithms to detect inconsistencies

The company thus facilitates the installation of state-of-the-art equipment and especially artificial intelligence (AI) in child care centers. “A large part of the radiology activity is concerned with inconsistency detection. AI makes these detections secure and reliable.”Alexander the Great observed.

Imadis now relies on five algorithms. He has been working with Israeli Aidoc since 2019 to detect intracranial hemorrhage, pulmonary embolism, rib fractures and cervical spine fractures during CT and MRI interpretations (90% of Imadis activity) and for several months X-ray fractures and fractures with French Medtech. Glimmer for displacement detection “Glamor solutions are being tested since 2020. We are now deploying it more widely.”.

Alexander the Great, however, insisted: “There is always a humanistic analysis, nothing is completely sub-contracted with AI. Artificial intelligence does not replace the radiologist, let’s be very clear on this point. On the other hand, it can highlight points that can be avoided by professionals. Let’s compare. The internal AI of the hospital, to which the head of the department has handed over a pile of files for examination. This may identify a new inconsistency. “.

According to an internal study by Aidoc, its algorithms thus make it possible to correct the diagnosis in 0.5% of cases for internal bleeding and 1% for pulmonary embolism. “It may seem like a relatively low price, but with Emadis caring for about 800 patients per day, the benefits for the patient are significant.”Leon notes SME.

“We are also gaining momentum, because the negative predictive value of AI is very strong.”Alexander Benn continues to check, noting that the performance of the algorithm has greatly improved since its debut in this area in 2018. “The detection spectrum has been expanded and false positives have been significantly reduced”.

80 recruitments to the 2022 program

Imadis relies on a team of 90 staff (support teams) and more than 300 radiologists, of whom more than a hundred are associated with the capital. In 2021, 114 Imadis joined the team and 80 should do so by 2022. Emadis Childcare Centers has interpreted more than a million tests for the hospital’s nearly 100 customer hospitals (including 40 new ones since the health crisis) since the company was formed.

The company has achieved a turnover of 18 million euros in 2021 and expects significant growth in 2022, having already opened two new centers (Disney and Clermont-Ferrand). The 2022 game plan thus targets a turnover of 23 million euros.

In its market, Imadis comes up against competitors like Télédiag, Nehs Digital and even Medin +, but is already emerging as the French leader in remote emergency radiology.
