Emory Healthcare Researcher Wins Two Awards Using Konica Minolta’s AI Analysis Tool with Dynamic Digital X-Ray in Shoulder Pathology

October 17, 2022 — Konica Minolta Healthcare Americas, Inc., congratulates Emory Healthcare researchers who won two awards at 2022 Orthopedic Research and Education Foundation (OREF) Eastern Region Resident Research Symposium for the presentation, “Automated Artificial Intelligence Analysis of Scapula Dynamics Using Dynamic Digital Radiography: An Initial Reliability Study.” Zaamin B. HussainMD, an orthopedic surgery resident working with Eric WagnerMD, MSc, Director of Upper Extremity Research and Adjunct Professor at Emory Health, received a Second Place Award and the Presenter’s Choice Award. Then, he will present his research to the OREF National Colloquium Later this year.

Dr. Hussain’s research evaluated a prototype artificial intelligence (AI) tool developed by Konica Minolta Healthcare to characterize shoulder dynamics. Seventy-three shoulders (23 normal controls, 41 rotator cuff tears, and nine adhesive capsulitis) were imaged using Dynamic Digital Radiography (DDR) and reviewed by two trained readers.

With DDR image data, Dr. Hussain was able to visualize changes in shoulder pathology and, using proof of concept AI tool, acquire measurements to calculate the scapulohumeral rhythm (SHR). The SHR measurement is a manual and time-consuming process to calculate the glenohumeral ratio and assess the function of the shoulder joint. The new AI tool uses a machine learning algorithm using a convolutional neural network architecture to automate this analysis. Dr. Hussain’s research demonstrated that the AI ​​tool has good reliability (ICC 0.58 (95% confidence interval 0.4-0.71)) between manual and AI measurements of SHR.

“We have demonstrated early promise for this AI tool, which can enable faster measurement of SHR and enable automated image analysis and diagnosis in shoulder pathology,” says Dr. Hussain. “DDR offers the best of both worlds: it allows us to dynamically visualize the shoulder while it is in motion and allows a quantitative measurement of the anatomy of the shoulder in motion, the gold standard for discerning changes in joint anatomy. Further improvement of the prototype AI tool could lead to more efficient integration of SHR measurements into the clinical workflow and increase the clinical utility of DDR in a clinical setting.

Konica Minolta has partnered with Emory Healthcare, one of the nation’s most comprehensive academic healthcare systems, and its physicians at Orthopedics & Spine Hospital, including Drs. Wagner and Hussain, to assess the clinical value of DDR in an orthopedic setting. The AI ​​prototype tool for SHR measurements is the achievement of research and development at Konica Minolta in AI-assisted image analysis and diagnosis with DDR. This is a new imaging application to assess the two critical shoulder joints allowing physicians to better understand the patient’s injury. As institutions adopt DDR into clinical practice, Konica Minolta continues to work with these centers to provide the technical and technological support needed to evaluate new and existing uses of this new technology.

“One of the most exciting aspects of DDR is the ability to see what’s going on in a patient’s joints in a way we’ve never been able to see before,” says Dr. Wagner. “In patients with limited range of motion, I can pinpoint where the patient is having difficulty and see the source of the limitations. This information is particularly useful in treatment decisions and pre-surgical planning. For example, in the shoulder, using DDR, we can differentiate motion limitations of the shoulder versus the scapula, potentially improving our diagnostic and therapeutic algorithms. New tools that help quantify how structures move relative to each other only add to our knowledge of the individual patient so we can deliver the best possible outcome. Although this work and collaboration has already resulted in national and international presentations, publications and research awards, we are only seeing the tip of the iceberg with this technology.

“Konica Minolta is committed to listening to the needs of its customers and providing solutions that help them answer a clinical question so they can continue to make a difference in patient care,” said John Sabol, PhD, Head of Clinical Research at Konica Minolta Healthcare. “Together with our academic and clinical users, we can advance the science behind DDR, whether thoracic, orthopedic or anatomical imaging, enabling them to improve radiography with the goal of reducing costs and taking better decisions, sooner.”
