Quality Scanning and Positioning for Hologic and GE Scanners
Saturday, April 25, 2026, 1:30pm - 2:30pm Eastern Time (NY/USA)
Description and Objectives
This session will provide an in-depth, technologist-focused review of DXA acquisition and analysis variability across manufacturers, with emphasis on accurate region-of-interest (ROI) placement and interpretation for spine and hip examinations. Participants will examine common sources of technologist error, including suboptimal patient positioning, inappropriate post-acquisition analysis adjustments, and incorrect scan mode selection, and will learn strategies to prevent these pitfalls. The session will underscore the critical role of immediate scan review while the patient remains present, particularly for ensuring correct bone mapping and diagnostic integrity. In addition, participants will explore challenges related to serial comparability and review manufacturer-specific software glitches that may impact longitudinal bone density assessment.
After attending this lecture, participants will be able to:
- Compare manufacturer-specific differences in region-of-interest (ROI) placement and analysis for spine and hip scans.
- Explain sources of technologist error including pitfalls of poor-quality positioning, inappropriate adjustments to the scan analysis, and improper scan mode selection.
- Recognize the importance of immediate scan review while the patient is present especially in the context of appropriate bone mapping.
- Describe serial comparability challenges and manufacturer-specific glitches.
