The Russian company launched a disease diagnosis service for MRI images

As it became known at the end of May 2021, the American company Remedy Logic launched a diagnostic system that allows you to detect central, lateral and foraminal stenoses of the lumbar spine, arthrosis and hernia on MRI images. Artificial intelligence, which determines pathology and offers treatment options, was developed by the Russian company Nanosemantika.

According to Kommersant, the service was launched on the Remedy Logic website. To use it, the patient first undergoes a questionnaire to make a more accurate diagnosis.

Suppose our system sees a large hernia in the picture, but the patient does not feel severe pain, moves normally. Without a questionnaire, the system would not take into account the patient's feelings and offered surgery, although in fact you can do with physical therapy or drug treatment, "explained Vladislav Tumko, lead developer of Nanosemantika Data Science, project manager for the creation of a diagnostic system.

After completing the questionnaire, the user downloads MRI images to the system. The system analyzes them and issues a detailed diagnosis along with treatment recommendations based on statistics of similar cases.

Each MRI image passes through two neural networks: a classifier and a segmentator. A classifier is an algorithm that assigns each object to a predetermined class based on the characteristics of the object. A segmenter is an algorithm for selecting objects and their boundaries in a snapshot. For segmentation of physiological objects, the images use a publicly available U-Net neural network, adapted for the purpose of the project.

By the end of May 2021, Nanosemantika is working to expand the functionality of the service. In particular, it is planned to organize the diagnosis of all lumbar pathologies, then go to the cervical and thoracic parts of the spine and to the limbs.^[1][2]
