During the novel Coronavirus emergency, operations and workflows in all Italian hospitals were disrupted, which significantly increased workloads. As a consolidated partner of Vimercate, Fujifilm wanted to ensure its cutting-edge tools were available to reduce the impact caused by the rapid spread of COVID-19 and to give a timely response to the spread of the pandemic.

In November 2019, a collaboration agreement between ASST of Vimercate and Fujifilm was signed with a view to exploring new approaches to the treatment of patients, with benefits both to the clinical services and to healthcare operators.

“REiLI’s support,” says Marcello Intotero, Head of Radiology Structure and Diagnostic Services Department, “has allowed our radiologists to report examinations with greater speed and efficiency. In numerical terms, their workloads have not particularly increased, as other causes for non-urgent examinations were limited to avoid an excess flow of patients. This new technology has given great support to the workflow; all images that artificial intelligence identified as suspected COVID-19 were subjected to processing by the radiologist in a faster and more urgent manner than other images which, instead, the system analyzed as corresponding to a healthy lung.”

REiLI’s processing of CT scans and chest x-rays provides important support for radiologists, offering them an extremely rapid, quantitative and objective assessment of the various zones of the lungs. The chest x-ray, in particular, is the best example of applying the new AI technology, in that it is a quick and simple examination which provides a large amount of useful information for evaluating the presence of the pulmonary parenchymal consolidation caused by the virus.

The data obtained from artificial intelligence does not replace the molecular diagnoses performed using the nasopharyngeal swab (RT-PCR) and, above all, nor does it replace the precious analyses and diagnoses performed by the radiologist. The data, however, does provide support in reporting on daily examinations conducted to monitor and study the development of the disease, and constitute a second opinion for the operators.

REiLI, Fujifilm’s Artificial Intelligence platform, is integrated with the Lunit Insight CXR module for the analysis and detection of the main types of pulmonary disease (nodules, atelectasis, fibrosis, calcifications, cardiomegaly, etc.). In fact, the Lunit Insight CXR3 module has been updated to provide support in specifically identifying the pulmonary parenchymal consolidation caused by the virus.

REiLI has been installed at ASST Vimercate in just two weeks, by installing a parallel PACS to avoid interrupting the daily workflow. On 30 March, REiLI was already operating and during its first five days it had worked on more than 600 images. During the emergency, more than 900 positive cases of COVID-19 were found, with an average of 80 chest x-rays per day, allowing precise and punctual data collection.
