Radiologists at The University of Innsbruck Rely on SEARCH Lung CT From Contextflow

Almost every second computed tomography (CT) scan of the lung shows abnormal findings. Most of the time these are pulmonary nodules, one possible indicator of cancer. But which findings are harmless and which need to be checked and treated? Assessing lung CTs is no simple task, but radiologists are increasingly finding support in new technologies. Contextflow SEARCH Lung CT is a clinical decision support system that detects, visualizes, and quantifies lung anomalies and pulmonary nodules. "In detail, it provides location and extent of changes and heat maps for six image patterns, as well as visualizations and measurements of detected pulmonary nodules. In addition, the tool analyzes and classifies 19 image patterns in selected regions of a scan; retrieves visually-similar, expert-verified reference cases; and provides relevant links to literature, guidelines, and differential diagnoses," explains Markus Krenn, Chief Product Officer at Contextflow.

A deep learning-based solution to simplify daily work

Since October 2021, a team of radiologists led by PD Mag. Dr. Med. Univ. Gerlig Widmann, Managing Senior Physician at the University Department of Radiology at the Medical University of Innsbruck, has been using SEARCH Lung CT. "We expect significant added value for our work and the patients, particularly on account of the system’s ability to quantify lung anomalies. The software provides us with percentages of pathological changes, visualizes the dynamics of these changes over time, and suggests reference cases with similar findings and diagnostic literature for differential diagnosis," says Dr. Widmann. The University Department of Radiology at the Medical University of Innsbruck is one of the largest institutions for radiological diagnostics in Austria and treats the vast majority of lung patients in Tyrol in close cooperation with the departments of oncology, thoracic surgery, pneumology, and the lung department of Natters Hospital. The first experiences with SEARCH Lung CT have been thoroughly positive, as the managing senior physician continues: "The segmentation of abnormalities such as shadows, reticular patterns or emphysema works extremely well. The platform is very clearly structured with references to current literature, including pattern descriptions and a list of possible differential diagnoses. You can clearly see that there is a valid reference data set behind the AI."

Last but not least, Dr. Widmann also expects to be able to establish a diagnosis more quickly: in a recent study at the Medical University of Vienna, the average report reading time was 31% shorter when SEARCH Lung CT was available for use*. These findings were true for both young and experienced radiologists.

Integration with Dedalus DeepUnity PACS ensures smooth workflow

"The implementation of SEARCH Lung CT was simple, quick, and straightforward. The cooperation between our IT and Contextflow was exemplary," says Dr. Widmann happily.

The clinical decision support software is seamlessly integrated into the hospital's Dedalus DeepUnity PACS. A radiologist wishing to use SEARCH Lung CT only has to click one button to seamlessly continue working with the tool. The images are then automatically evaluated and transferred to the report. "It's all very simple. So far we are very satisfied with SEARCH Lung CT," concludes Dr. Widmann.
