AI would save radiologists an hour a day in clinical practice

According to the American Journal of Roentgenology (AJR), integrating AI support into clinical practice can reduce repetitive tasks for radiologists. In particular, it saves about an hour of time spent interpreting chest CTs on a typical workday.

A study by Dr. U. Joseph Schoepf from the Medical University of South Carolina in Charleston (South Carolina – USA) proposes to evaluate the time savings possible through the use of artificial intelligence (AI) in the practice of radiologists for the reading of breast scans.

A study to evaluate time savings in AI-enabled radiology practice

“This is, to our knowledge, the first study to measure the impact of an AI-assist platform on chest CT interpretation times in a real-world clinical setting,” said Dr. About this work in the American Journal of Roentgenology. Integrating the platform into clinical workflow resulted in an average 22.1% reduction in interpretation times for three cardiothoracic radiologists who were provided with AI results. »

This prospective study included 390 patients (204 females, 186 males; mean age: 62.8 years) who underwent ambulatory chest computed tomography (CT) on January 19-28, 2021. A commercial software solution, AI-Rad Companion, provided automated analysis of cardiac, pulmonary, and musculoskeletal findings, as well as marking, segmentation, and measurement of normal structures or abnormalities. AI-annotated images and automatically generated summary results were stored in PACS. Chest CT scans were randomized using a 1:1 split between IA-assisted and non-IA arms and then clinically interpreted using a timer.

One hour of interpreting saved every day

Finally, the mean interpretation times at all three cardiothoracic radiologists were significantly shorter in the IA-assisted arm than in the non-IA arm. For all readers, the mean difference was 93 seconds (95% CI, 63 to 123 seconds), representing a 22.1% reduction in the AI-assisted arm: 20.0% and 24.2% for scans with and without, respectively contrast media.

“If supporting automated AI interpretations can save an hour of interpretation time each day, as our results show, say the authors of this article, then radiologists could spend that time on other activities, be it additional clinical tasks such as transmitting results to patients and referring physicians, or for administrative, educational, or research purposes. »
