Osteoporosis is a major health problem that affects more than 28 million people in the U.S. Ongoing research advances have created optimism and treatment options for those who have been diagnosed with the disease. An early assessment of bone health with accurate and precise measurements is critical to the prevention and diagnosis of osteoporosis. This webinar will help you obtain a foundation in clinical bone densitometry as well as provide an in-depth understanding of the appropriate use and interpretation of dual x-ray absorptiometry (DEXA) scans. In addition, it will also be a valuable guide for those preparing for the ARRT or ISCD Bone Densitometry Certification Examinations. This webinar will be presented in two two-hour sessions.

![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
