CT Calculator: Moscow’s healthcare system offers a new service

December 25, 2020

The city has been developing digital healthcare services more actively since the pandemic. The new CT Calculator service, for example, helps doctors diagnose patients using computerised tomography (CT) and magnetic resonance imaging (MRI), Moscow Mayor Sergei Sobyanin said in an interview for This Week in the City on Rossiya 1.

“Even without CT scans, it is already possible to diagnose pneumonia cases and determine the stage of the disease with a probability of 90 percent,” the Mayor said.

The neural network was trained using case history data, laboratory tests, saturation levels and the overall clinical picture of COVID-19 patients diagnosed with pneumonia. All this data was matched against CT scans. Moscow doctors have treated over 500,000 people since March 2020 and have accumulated a huge amount of data.

The CT Calculator will be constantly updated with new data for more accurate diagnostics. Doctors in Moscow and other Russian regions will have access to it.

The CT Calculator helps doctors predict the possibility of minor (CT 0‒1), medium (CT 2) or severe (CT 3‒4) pneumonia and choose the best treatment in each case. “This is particularly important for patients whose condition has to be monitored continuously. A patient cannot be subjected to daily CT scans as it can have an adverse effect on his or her health,” Sobyanin added.

Doctors can decide against using computerised tomography if the system suggests that the patient has a minor case of pneumonia. In more severe cases, based on the system’s data, doctors will prescribe a CT scan or an X-ray immediately as well as intensive treatment.

Other healthcare innovations include online medical records containing the results of laboratory and other tests, including COVID-19 swab and antibody tests.

A telemedicine centre opened in Moscow earlier this year. The centre proved extremely helpful during the pandemic because doctors were able to hold thousands of remote consultations for COVID-19 patients recovering at home.

Artificial intelligence is another technology that effectively assists doctors. The city is currently testing experimental services that process CT scans, mammograms and X-ray scans. AI services are incorporated into the Integrated Medical Information and Analytical System (IMIAS). The tests help diagnose lung cancer, pneumonia and other pulmonary conditions, breast cancer and COVID-19. The experiment has already produced first results: AI diagnostics is faster and more accurate. The technology prevents doctors from overlooking disorders in a large volume of patient data and helps them to identify high-risk cases.
