Abstract

Dual-energy X-ray absorptiometry is the gold standard for evaluating Bone Mineral Density (BMD); however, a typical BMD report is generated in a time-inefficient manner and is prone to error. We developed a rule-based automated reporting system, BatchBMD, that accelerates DXA reporting while improving its accuracy over current systems. BatchBMD generates a structured report, customized to the specific clinical purpose. To compare BatchBMD to a Web-based Reporting (WBR) system for efficiency and accuracy, 500 examinations were randomly chosen from those performed at the Taipei Municipal Wanfang Hospital from January to March 2021. The final assessment included all 2326 examinations conducted from September 2020 to March 2021. The average reporting times were 6.7 and 10.8 min for BatchBMD and the WBR system, respectively, while accuracy was 99.4% and 98.2%, respectively. Most of the errors made by BatchBMD were digit errors in the appendicular skeletal muscle index. After correcting this, 100% accuracy across all 2326 examinations was validated. This automated and accurate BMD reporting system significantly reduces report production workload for radiologists and technicians while increasing productivity and quality. Additionally, the portable software, which employs a simple framework, can reduce deployment costs in clinical practice.

Summary

Introduction

Mineral Density (BMD) at the lumbar spine, hip, and forearm, for those with osteoporosis [1], a metabolic disease characterized by increased risks of bone fragility and compression fractures. DXA is the gold standard for diagnosing osteoporosis, predicting fragility fracture, and monitoring treatment [2,3]. Osteoporosis becomes much more prevalent; a more efficient means of generating BMD reports will be necessary as the demand for DXA examinations increases [4–7]. The risk level of osteoporosis is categorized using the DXA images and the 2019 International Society for Clinical Densitometry (ISCD) Official Positions for Adults [8]. Manual data entry of the BMD data (lumbar spine, hip, and femur) requires a couple of minutes; the T- and Z-scores are automatically calculated using young adult and age-matched reference populations, respectively [9,10]
