Standing X-Ray vs. lying MRI: which shows your true neck curve?
NCT ID NCT07541586
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at how the natural curve of the neck (cervical lordosis) differs when measured on a standing X-ray versus a lying-down MRI. Researchers will compare images from 58 adults without neck problems to see if body position changes the measurement. The goal is to help doctors better understand and interpret these common spine images.
